[03] The ability of Clostridial toxins, such as, e.g., Botulinum neurotoxins (BoNTs), BoNT/A, BoNT/B, BoNT/C1, BoNT/D, BoNT/E, BoNT/F and BoNT/G, and Tetanus neurotoxin (TeNT), to inhibit neuronal transmission are being exploited in a wide variety of therapeutic and cosmetic applications, see e.g., William J. Lipham, COSMETIC AND CLINICAL APPLICATIONS OF BOTULINUM TOXIN
(Slack, Inc., 2004).
Clostridial toxins commercially available as pharmaceutical compositions include, BoNT/A preparations, such as, e.g., BOTOX (Allergan, Inc., Irvine, CA), Dysport /Reloxin , (Beaufour Ipsen, Porton Down, England), Linurase (Prollenium, Inc., Ontario, Canada), Neuronox (Medy-Tox, Inc., Ochang-myeon, South Korea) BTX-A (Lanzhou Institute Biological Products, China) and Xeomin (Merz Pharmaceuticals, GmbH., Frankfurt, Germany); and BoNT/B preparations, such as, e.g., MyoBlocT"'/NeuroBlocT"' (Elan Pharmaceuticals, San Francisco, CA).

[04] A Clostridial toxin treatment inhibits neurotransmitter release by disrupting the exocytotic process used to secret the neurotransmitter into the synaptic cleft. There is a great desire by the pharmaceutical industry to expand the use of Clostridial toxin therapies beyond its current myo-relaxant applications to treat sensory-based ailment, such as, e.g., various kinds of chronic pain, as well as non-neuronal based disorders, such as, e.g., pancreatitis. One approach that is currently being exploited to expand Clostridial toxin-based therapies involves modifying a Clostridial toxin so that the modified toxin has an altered cell targeting capability for a non-Clostridial toxin target cell. This re-targeted capability is achieved by replacing a naturally-occurring targeting domain of a Clostridial toxin with a targeting domain showing a selective binding activity for a non-Clostridial toxin receptor present in a non-Clostridial toxin target cell.
Such modifications to a targeting domain result in a modified toxin that is able to selectively bind to a non-Clostridial toxin receptor (target receptor) present on a non-Clostridial toxin target cell (re-targeted). A
modified Clostridial toxin with an altered targeting activity for a non-Clostridial toxin target cell can bind to a target receptor, translocate into the cytoplasm, and exert its proteolytic effect on the SNARE complex of the non-Clostridial toxin target cell.

Steward et al., Multivalent Clostridial Toxin Derivatives and Methods of Their Use, U.S. Patent Application No. 11/376,696 (Mar. 15, 2006).

As a non-limiting example, modified Clostridial toxins retargeted to sensory neurons are useful in treating various kinds of chronic pain, such as, e.g., hyperalgesia and allodynia, neuropathic pain and inflammatory pain, see, e.g., Foster, supra, (1999); and Donovan, supra, (2002); and Stephan Donovan, Method For Treating Neurogenic Inflammation Pain with Botulinum Toxin and Substance P
Components, U.S. Patent 7,022,329 (Apr. 4, 2006). As another non-limiting example, modified Clostridial toxins retargeted to pancreatic cells are useful in treating pancreatitis, see, e.g., Steward, supra, (2005).

[06] The present invention provides novel Clostridial toxins that greatly extended the number of therapeutic applications that can exploit the advantages offered by current Clostridial toxin therapies.
These modified Clostridial toxins comprise, in part, a translocation facilitating domain that enhances the process by which a light chain from a modified toxin translocates into the cytoplasm of a target cell and enzymatically modify its target SNARE substrate. Thus modified Clostridial toxins with an altered targeting activity for a non-Clostridial toxin target cell, such as those disclosed in, e.g., Foster, supra, (1999), Dolly, supra, (2001), Donovan, supra, (2002), Shone, supra, (2002), Foster, supar, (2003), Quinn, supra, (2003), Foster, supra, (2005), Steward, supra, (2005) and Steward, supra, (2006) comprising a translocation facilitating domain disclosed in the present specification, exhibit increased potency at the non-Clostridial toxin target cell. These and related advantages are useful for various clinical, therapeutic and cosmetic applications, such as, e.g., the treatment of neuropathic disorders, eye disorders, pain, muscle injuries, headache, cardiovascular diseases, neuropsychiatric disorders, endocrine disorders, cancers, otic disorders, as well as, other disorders where administration of a modified Clostridial toxin with an altered targeting activity for a non-Clostridial toxin target cell to an individual can produce a beneficial effect.

BRIEF DESCRIPTION OF THE DRAWINGS
[07] FIG. 1 shows a schematic of the current paradigm of neurotransmitter release and Clostridial toxin intoxication in a central and peripheral neuron. FIG. 1A shows a schematic for the neurotransmitter release mechanism of a central and peripheral neuron. The release process can be described as comprising two steps: 1) vesicle docking, where the vesicle-bound SNARE
protein of a vesicle containing neurotransmitter molecules associates with the membrane-bound SNARE proteins located at the plasma membrane; and 2) neurotransmitter release, where the vesicle fuses with the plasma membrane and the neurotransmitter molecules are exocytosed. FIG. 1 B shows a schematic of the intoxication mechanism for tetanus and botulinum toxin activity in a central and peripheral neuron.
This intoxication process can be described as comprising four steps: 1) receptor binding, where a Clostridial toxin binds to a Clostridial receptor and initiates the intoxication process; 2) complex internalization, where after toxin binding, a vesicle containing the toxin/receptor complex is endocytosed into the cell; 3) light chain translocation, where multiple events result in the release of the active light chain into the cytoplasm; and 4) enzymatic target modification, where the active light chain of Clostridial toxin proteolytically cleaves its target SNARE
substrate, such as, e.g., SNAP-25, VAMP or Syntaxin, thereby preventing vesicle docking and neurotransmitter release.

As depicted above the single-chain form, the Hcc targeting domain comprises the (3-trefoil domain which comprises in an amino to carboxyl linear organization of an a-fold, a(34/(35 hairpin turn, a(3-fold, a(38/(39 hairpin turn and a y-fold.

DETAILED DESCRIPTION
[014] Clostridia toxins produced by Clostridium botulinum, Clostridium tetani, Clostridium baratii and Clostridium butyricum are the most widely used in therapeutic and cosmetic treatments of humans and other mammals. Strains of C. botulinum produce seven antigenically-distinct types of Botulinum toxins (BoNTs), which have been identified by investigating botulism outbreaks in man (BoNT/A, /B, /E and /F), animals (BoNT/C1 and /D), or isolated from soil (BoNT/G). While all seven botulinum toxins (BoNT) serotypes have similar structure and pharmacological properties, each also displays heterogeneous bacteriological characteristics. In contrast, tetanus toxin (TeNT) is produced by a uniform group of C.
tetani. Two other species of Clostridia, C. baratii and C. butyricum, also produce toxins similar to BoNT/F
and BoNT/E, respectively.
tetani. Two other species of Clostridia, C. baratii and C. butyricum, also produce toxins similar to BoNT/F
and BoNT/E, respectively.
[015] Clostridia toxins possess approximately 35% amino acid identity with each other and share the same functional domain organization and overall structural architecture.
Clostridial toxins are each translated as a single chain polypeptide of approximately 150 kDa that is subsequently cleaved by proteolytic scission within a disulfide loop by a naturally-occurring protease, such as, e.g., an endogenous Clostridial toxin protease or a naturally-occurring protease produced in the environment (see FIG. 2).
This posttranslational processing yields a di-chain molecule comprising an approximately 50 kDa light chain (LC) and an approximately 100 kDa heavy chain (HC) held together by a single disulfide bond and noncovalent interactions. It is widely held that the mature di-chain molecule comprises three functionally distinct domains: 1) an enzymatic domain located in the LC that includes a metalloprotease region containing a zinc-dependent endopeptidase activity which specifically targets core components of the neurotransmitter release apparatus (Table 1); 2) a translocation domain contained within the amino-terminal half of the heavy chain (HN domain) that facilitates release of the LC from intracellular vesicles into the cytoplasm of the target cell (Table 1); and 3) a binding domain found within the carboxyl-terminal half of the heavy chain (Hc domain) that determines the binding activity and binding specificity of the toxin to the receptor complex located at the surface of the target cell (Table 1), see, e.g., Kathryn Turton et al., Botulinum and Tetanus Neurotoxins: Structure, Function and Therapeutic Utility, 27(11) Trends Biochem.

The current paradigm describes the intoxication mechanism as comprising at least four steps: 1) receptor binding, 2) complex internalization, 3) light chain translocation, and 4) enzymatic target modification (see FIG. 1). The process is initiated when the Hc domain of a Clostridial toxin binds to a toxin-specific receptor located on the plasma membrane surface of a target cell. The binding specificity of a receptor complex is thought to be achieved, in part, by specific combinations of gangliosides and protein receptors that appear to distinctly comprise each Clostridial toxin receptor complex. Once bound, the toxin/receptor complexes are internalized by endocytosis and the internalized vesicles are sorted to specific intracellular routes.
The translocation step, now thought to be mediated by the HN domain and further facilitated by the HCN
domain, appears to be triggered by the acidification of the vesicle compartment. This process seems to initiate two important pH-dependent structural rearrangements that increase hydrophobicity and promote separation of the light chain from the heavy chain of the toxin. Once activated, light chain endopeptidase of the toxin is released from the intracellular vesicle into the cytosol where it appears to specifically target one of three known core components of the neurotransmitter release apparatus.
These core proteins, vesicle-associated membrane protein (VAMP)/synaptobrevin, synaptosomal-associated protein of 25 kDa (SNAP-25) and Syntaxin, are necessary for synaptic vesicle docking and fusion at the nerve terminal and constitute members of the soluble N-ethylmaleimide-sensitive factor-attachment protein-receptor (SNARE) family. BoNT/A and BoNT/E cleave SNAP-25 in the carboxyl-terminal region, releasing a nine or twenty-six amino acid segment, respectively, and BoNT/C1 also cleaves SNAP-25 near the carboxyl-terminus. The botulinum serotypes BoNT/B, BoNT/D, BoNT/F and BoNT/G, and tetanus toxin, act on the conserved central portion of VAMP, and release the amino-terminal portion of VAMP into the cytosol. BoNT/C1 cleaves syntaxin at a single site near the cytosolic membrane surface. The selective proteolysis of synaptic SNAREs accounts for the block of neurotransmitter release caused by Clostridial toxins in vivo. The SNARE protein targets of Clostridial toxins are common to exocytosis in a variety of non-neuronal types; in these cells, as in neurons, light chain peptidase activity inhibits exocytosis, see, e.g., Yann Humeau et al., How Botulinum and Tetanus Neurotoxins Block Neurotransmitter Release, 82(5) Biochimie. 427-446 (2000); and Giovanna Lalli et al., The Journey of Tetanus and Botulinum Neurotoxins in Neurons, 11(9) Trends Microbiol. 431-437, (2003).
Clostridial toxins are each translated as a single chain polypeptide of approximately 150 kDa that is subsequently cleaved by proteolytic scission within a disulfide loop by a naturally-occurring protease, such as, e.g., an endogenous Clostridial toxin protease or a naturally-occurring protease produced in the environment (see FIG. 2).
This posttranslational processing yields a di-chain molecule comprising an approximately 50 kDa light chain (LC) and an approximately 100 kDa heavy chain (HC) held together by a single disulfide bond and noncovalent interactions. It is widely held that the mature di-chain molecule comprises three functionally distinct domains: 1) an enzymatic domain located in the LC that includes a metalloprotease region containing a zinc-dependent endopeptidase activity which specifically targets core components of the neurotransmitter release apparatus (Table 1); 2) a translocation domain contained within the amino-terminal half of the heavy chain (HN domain) that facilitates release of the LC from intracellular vesicles into the cytoplasm of the target cell (Table 1); and 3) a binding domain found within the carboxyl-terminal half of the heavy chain (Hc domain) that determines the binding activity and binding specificity of the toxin to the receptor complex located at the surface of the target cell (Table 1), see, e.g., Kathryn Turton et al., Botulinum and Tetanus Neurotoxins: Structure, Function and Therapeutic Utility, 27(11) Trends Biochem.

[017] The three-dimensional crystal structures of BoNT/A, BoNT/B and the Hc domain of TeNT indicate that the three functional domains of Clostridial neurotoxins are structurally distinct (see FIG. 3). The HEXXH consensus motif of the light chain forms the tetrahedral zinc binding pocket of the catalytic site located in a deep cleft on the protein surface that is accessible by a channel. The structure of the HN and Hc domains consists primarily of (3-sheet topologies that are linked by a single a-helix. The cylindrical-shaped HN domain comprises two long amphipathic a-helices that resemble the coiled-coil motif found in some viral proteins. The HN domain also forms a long unstructured loop called the `translocation belt,' which wraps around a large negatively charged cleft of the light chain that blocks access of the zinc atom to the catalytic-binding pocket of active site. The Hc domain comprises two distinct structural features of roughly equal size that indicate function. The first, designated the HCN
domain, is located in the amino half of the Hc domain. The HCN domain forms a(3-barrel, jelly-roll fold. The Hcc domain is the second domain that comprises the Hc domain. This carboxyl-terminal domain comprises a modified (3-trefoil domain which forms three distinct carbohydrate binding regions that resembles the carbohydrate binding moiety found in many sugar-binding proteins, such as, e.g., serum amyloid P, sialidase, cryia, insecticidal a-endotoxin and lectins. Biochemical studies indicate that the (3-trefoil domain structure of the Hcc domain appears to mediate the binding to specific carbohydrate containing components of the Clostridial toxin receptor on the cell surface, see, e.g., Krzysztof Ginalski et al., Structure-based Sequence Alignment for the Beta-Trefoil Subdomain of the Clostridial Neurotoxin Family Provides Residue Level Information About the Putative Ganglioside Binding Site, 482(1-2) FEBS Lett.

[018] We know that only the Hcc domain participates in receptor binding because the (3-trefoil domains are restricted to this domain. Proteins containing the structural (3-trefoil domain represents a diverse group of proteins organized into at least eight superfamilies including the cytokines, MIR domain proteins, Ricin B-like lectins, agglutinins, Soybean trypsin inhibitor like proteins, Actin-crosslinking proteins, LAG-1 proteins and AbfB domain proteins, see, e.g., C. A. Orengo et al., Protein Superfamilies and Domain Superfolds, 372 Nature 631-634 (1994); and Alexey G. Murzin et al., SCOP: A

Mol. Biol. 536-540 (1995).
While having diverse cellular roles, members of these superfamilies mechanistically function via protein-protein associations through the (3-trefoil domain. Of particular interest is the fact that many of these members are specifically involved in receptor interactions, including, e.g., the cytokine superfamily members Fibroblast Growth Factors (FGFs) and the Interleukin-1s (IL-1s); the Ricin B-like lectins; the agglutinins; and STI-like members the Kunitz inhibitors and Clostridium neurotoxins. That only the Hcc domain alone mediates the cell binding step of intoxication is further supported by the finding that mutations that disrupt the receptor binding activity of Clostridial toxins have been confined to the Hcc domain, see, e.g., Andreas Rummel et al., The Hcc-Domain of Botulinum Neurotoxins A and B Exhibits a Singular Ganglioside Binding Site Displaying Serotype Specific Carbohydrate Interaction, 51(3) Mol.

[019] Because the Hcc domain appears not only necessary, but sufficient for selective binding of a Clostridial toxin to its receptor, we have deduced that the primary function of the HCN domain of Clostridial toxins is involved in the translocation step of the intoxication process, and not in the cell binding step, because the lack of HCN domain appears to reduce intoxication efficiency. For example, a modified BoNT/A comprising a Substance P targeting domain was inefficient in intoxicating its corresponding target cells. In this modified toxin, the entire BoNT/A Hc domain, comprising both the BoNT/A Hcc domain and the BoNT/A HCN domain, was replaced by the Substance P targeting domain.
Likewise, we have determined that several other modified Clostridial toxins that have replaced the entire BoNT/A Hc domain with an exogenous targeting domain have exhibited reduced intoxication capabilities. Thus, the HCN
domain possess a translocation facilitating function because 1) Hcc domain primarily mediates the receptor binding step of the intoxication process; 2) modified Clostridial toxins lacking the HCN domain exhibit a reduced ability to translocate into the cytoplasm as evident by such modified toxins exhibiting decreased proteolysis of their SNARE substrates; and 3) the LC domain mediates the enzymatic activity of the toxin. While the exact translocation facilitating mechanism of the HCN
domain is currently not understood, the HCN domain may 1) participate in the formation of an endosomal pore; 2) mediate the insertion of the pore into a vesicle membrane; 3) assist in the delivery of LC
across the endosomal membrane and/or 4) serve as a structural scaffold or spacer that facilitates the appropriate orientation a the targeting domain in relationship to the translocation domain. In this last point, the HCN domain would serve to orient the translocation domain to facilitate the proper presentation of the translocation domain for insertion into the membrane following binding of the ligand by the receptor. This novel role of teh HCN
domain in the translocation step is contrary to the widely accepted view that the Clostridial toxin HCN
domain played an integral role in the cell binding step of the intoxication process.

[020] Thus, the present invention discloses modified Clostridial toxins that exhibit 1) an enhanced translocation capability; and 2) an altered targeting capability for a naturally-occurring Clostridial toxin target cell. The enhanced translocation capability is mediated by a translocation facilitating domain comprising, e.g., a HCN region of Clostridial toxins. The HCN domain enhances the process by which the HN domain mediates the release of the light chain from internalized intracellular vesicles into the cytoplasm of the target cell during the translocation step. Enhanced translocation capability is obtained by including or maintaining a Clostridial toxin HCN domain in a modified Clostridial toxin disclosed in the present specification. The altered targeting capability for a naturally-occurring Clostridial toxin target cell is mediated by an altered targeting domain comprising a modified Hcc targeting domain of Clostridial toxins. The Hcc domain primarily determines the binding activity and binding specificity of the toxin to the receptor complex located at the surface of the target cell. Altered targeting activity is achieved by replacing a naturally-occurring Hcc targeting domain of a Clostridial toxin with a binding domain for a non-Clostridial toxin receptor present on a Clostridial toxin target cell [021] Thus modified Clostridial toxins with an enhanced translocation capability will reduce the undesirable dispersal of the toxin to areas not targeted for treatment, due to the lower dose requirement, thereby reducing or preventing the undesirable side-effects associated with diffusion of a Clostridial toxin to an unwanted location. Furthermore, an altered binding activity will provide novel Clostridial toxins that greatly extended the number of therapeutic applications that can exploit the advantages offered by current Clostridial toxin therapies.
[022] Thus, aspects of the present invention provide modified Clostridial toxins comprising a Clostridial toxin enzymatic domain, a Clostridial toxin translocation domain, a translocation facilitating domain and an altered targeting domain, wherein the modified Clostridial toxin exhibits a binding activity for a non-Clostridial toxin receptor present on a non-Clostridial toxin target cell. It is envisioned that any translocation facilitating domain capable of further facilitating the translocation step of the intoxication process where the light chain is released from intracellular vesicles into the cytoplasm of the target cell will be useful to practice aspects of the present invention, including, without limitation, a Clostridial toxin translocation facilitating domain and an enveloped virus fusogenic peptide domain. Likewise, a multitude of altered targeting domains are envisioned, including, without limitation, opioids, melanocortin peptides, galanins, granins, tachykinin peptides, cholecystokinins, Neuropeptide Y
related peptides, kinin peptides, PAR peptides, corticotropin-releasing hormones, thyrotropin-releasing hormones and somatostatins. It is also envisioned that the location of the altered targeting domain in the modified Clostridial toxins of the present specification can be located at the amino terminus of the toxin, between the enzymatic and translocation domains or at the carboxyl terminus of the toxin. Thus, a modified Clostridial toxins disclosed in the present specification can comprise an amino to carboxyl domain arrangement of, e.g., an altered targeting domain, a Clostridial toxin translocation domain, a translocation facilitating domain and a Clostridial toxin enzymatic domain; an altered targeting domain, a Clostridial toxin enzymatic domain, a Clostridial toxin translocation domain and a translocation facilitating domain; a Clostridial toxin enzymatic domain, an altered targeting domain, a Clostridial toxin translocation domain and a translocation facilitating domain; a Clostridial toxin translocation domain, a translocation facilitating domain, an altered targeting domain and a Clostridial toxin enzymatic domain; a Clostridial toxin enzymatic domain, a Clostridial toxin translocation domain, a translocation facilitating domain and an altered targeting domain;

[025] Aspects of the present invention provide, in part, a modified Clostridial toxin. As used herein, the term "modified Clostridial toxin" means any polypeptide that can execute the overall cellular mechanism whereby a Clostridial toxin enters a neuron and inhibits neurotransmitter release and encompasses the binding of a Clostridial toxin to a low or high affinity receptor complex, the internalization of the toxin, the translocation of the Clostridial toxin light chain into the cytoplasm and the enzymatic modification of a Clostridial toxin substrate. A modified Clostridial toxin disclosed in the present specification is distinguished from a naturally-occurring Clostridial toxin by the fact that a modified Clostridial toxin comprises a translocation facilitating domain that enhances the process by which a light chain from a modified toxin translocates into the cytoplasm of a target cell and a modified Clostridial toxin lacks the cell binding activity of a naturally-occurring binding domain found in a Clostridial toxin. Instead, a modified Clostridial toxin disclosed in the present specification comprises an altered targeting domain that determines the binding activity of the modified Clostridial toxin to a non-Clostridial toxin receptor located at the surface of the target cell. By definition, a naturally-occurring Clostridial toxin lacks an altered targeting domain. Examples of modified Clostridial toxin are described in, e.g., Keith A.

[036] As used herein, the term "active Clostridial toxin light chain fragment"
means any of a variety of Clostridial toxin fragments comprising the light chain can be useful in aspects of the present invention with the proviso that these light chain fragments can specifically target the core components of the neurotransmitter release apparatus and thus participate in executing the overall cellular mechanism whereby a Clostridial toxin proteolytically cleaves a substrate. The light chains of Clostridial toxins are approximately 420-460 amino acids in length and comprise an enzymatic domain (Table 1). Research has shown that the entire length of a Clostridial toxin light chain is not necessary for the enzymatic activity of the enzymatic domain. As a non-limiting example, the first eight amino acids of the BoNT/A light chain (residues 1-8 of SEQ ID NO: 1) are not required for enzymatic activity. As another non-limiting example, the first eight amino acids of the TeNT light chain (residues 1-8 of SEQ ID
NO: 8) are not required for enzymatic activity. Likewise, the carboxyl-terminus of the light chain is not necessary for activity. As a non-limiting example, the last 32 amino acids of the BoNT/A light chain (residues 417-448 of SEQ ID NO:
1) are not required for enzymatic activity. As another non-limiting example, the last 31 amino acids of the TeNT light chain (residues 427-457 of SEQ ID NO: 8) are not required for enzymatic activity. Thus, aspects of this embodiment can include Clostridial toxin light chains comprising an enzymatic domain having a length of, e.g., at least 350 amino acids, at least 375 amino acids, at least 400 amino acids, at least 425 amino acids and at least 450 amino acids.

A

[0128] As used herein, the term "non-conservative Clostridial toxin HCN region variant" means a Clostridial toxin HCN region in which 1) at least one amino acid is deleted from the reference Clostridial toxin HCN region on which the non-conservative Clostridial toxin HCN region variant is based; 2) at least one amino acid added to the reference Clostridial toxin HCN region on which the non-conservative Clostridial toxin HCN region is based; or 3) at least one amino acid is substituted by another amino acid or an amino acid analog that does not share any property similar to that of the original amino acid from the reference Clostridial toxin HCN region sequence (Table 1).

[0129] As used herein, the term "Clostridial toxin HCN region chimeric" means a polypeptide comprising at least a portion of a Clostridial toxin HCN region and at least a portion of at least one other polypeptide to form a toxin HCN region with at least one property different from the reference Clostridial toxin HCN regions of Table 1, with the proviso that this Clostridial toxin HCN region chimeric is still capable of further facilitating the translocation step of the intoxication process where the LC
is released from intracellular vesicles into the cytoplasm of the target cell and thus participate in executing the overall cellular mechanism whereby a Clostridial toxin proteolytically cleaves a substrate.
is released from intracellular vesicles into the cytoplasm of the target cell and thus participate in executing the overall cellular mechanism whereby a Clostridial toxin proteolytically cleaves a substrate.
[0130] As used herein, the term "active Clostridial toxin HCN region fragment"
means any of a variety of Clostridial toxin fragments comprising the HcN region can be useful in aspects of the present invention with the proviso that these active fragments can further facilitate the translocation step of the intoxication process where the LC is released from intracellular vesicles into the cytoplasm of the target cell and thus participate in executing the overall cellular mechanism whereby a Clostridial toxin proteolytically cleaves a substrate. The HCN domains from the heavy chains of Clostridial toxins are approximately 230-250 amino acids in length and comprise a translocation domain (Table 1). Additionally, while a specific amino acid positions have been identified to delineate the boundaries of the Clostridial toxin HCN region (Table 1), it is well known in the art that the functional boundaries are not definitive. For example, amino-terminus of the HCN domain for all naturally-occurring Clostridial toxins is the HN domain (translocation domain). In examining the structure for BoNT/A, a random coil linker region forms a boundary between the HN and HCN domains (see FIG. 7A). The BoNT/A HN domain appears to end with an a-helix comprising amino acids N859 to 1873. Following the a-helix there is a random coil (1873 to 1878) that leads into the HCN
domain where a(3-sheet begins at position 1878. The above residues define boundaries at the beginning or end of defined secondary structures and do not imply that there are not significant interactions (i.e., hydrophobic, H-bond, etc.) between residues in the random coil region and one or both of the domains that it links together. Thus, minimally an amino acid that defines the amino-terminal boundary of the BoNT/A HCN domain comprises can be any amino acid present in the amino acid region Y869 to L879.
Similar analysis indicates that minimally, the amino acid that defines the amino-terminal boundary of the BoNT/B HCN domain can be any amino acid present in the amino acid region Y856 to L866; the amino acid that defines the amino-terminal boundary of the BoNT/C1 HCN domain can be any amino acid present in the amino acid region Y864 to L874; the amino acid that defines the amino-terminal boundary of the BoNT/D HCN domain can be any amino acid present in the amino acid region Y860 to L870; the amino acid that defines the amino-terminal boundary of the BoNT/E HCN domain can be any amino acid present in the amino acid region F843 to L853; the amino acid that defines the amino-terminal boundary of the BoNT/F HCN domain can be any amino acid present in the amino acid region L862 to L872; the amino acid that defines the amino-terminal boundary of the BoNT/G HCN domain can be any amino acid present in the amino acid region Y861 to L871; and the amino acid that defines the amino-terminal boundary of the TeNT HCN domain can be any amino acid present in the amino acid region 1877 to L887.
means any of a variety of Clostridial toxin fragments comprising the HcN region can be useful in aspects of the present invention with the proviso that these active fragments can further facilitate the translocation step of the intoxication process where the LC is released from intracellular vesicles into the cytoplasm of the target cell and thus participate in executing the overall cellular mechanism whereby a Clostridial toxin proteolytically cleaves a substrate. The HCN domains from the heavy chains of Clostridial toxins are approximately 230-250 amino acids in length and comprise a translocation domain (Table 1).

Thus, minimally an amino acid that defines the amino-terminal boundary of the BoNT/A HCN domain comprises can be any amino acid present in the amino acid region Y869 to L879.
Similar analysis indicates that minimally, the amino acid that defines the amino-terminal boundary of the BoNT/B HCN domain can be any amino acid present in the amino acid region Y856 to L866; the amino acid that defines the amino-terminal boundary of the BoNT/C1 HCN domain can be any amino acid present in the amino acid region Y864 to L874; the amino acid that defines the amino-terminal boundary of the BoNT/D HCN domain can be any amino acid present in the amino acid region Y860 to L870; the amino acid that defines the amino-terminal boundary of the BoNT/E HCN domain can be any amino acid present in the amino acid region F843 to L853; the amino acid that defines the amino-terminal boundary of the BoNT/F HCN domain can be any amino acid present in the amino acid region L862 to L872; the amino acid that defines the amino-terminal boundary of the BoNT/G HCN domain can be any amino acid present in the amino acid region Y861 to L871; and the amino acid that defines the amino-terminal boundary of the TeNT HCN domain can be any amino acid present in the amino acid region 1877 to L887.
[0131] Similarly, the carboxyl-terminal portion of the HCN domain (i.e., the fusion point between the HCN
and Hcc domains) all naturally-occurring Clostridial toxins comprises a range of amino acids. In defining the boundary of the BoNT/A HCN domain as the beginning or the end of ordered secondary structure, the HCN domain could end at Q1091 of an a-helix and the Hcc domain could begin at K1109 of a(3-strand (see FIG. 7B). The intervening amino acid sequence between these two domains comprises a longer random coil but, this does not imply that the random coil is not structurally important. In fact, this random coil has a great deal of interaction with both the HCN and Hcc domains (i.e., hydrophobic and H-bonding).
Thus, minimally an amino acid that defines the carboxyl-terminal boundary of the BoNT/A HCN domain comprises can be any amino acid present in the amino acid region D1089 to Y1111. Similar analysis indicates that minimally, the amino acid that defines the carboxyl-terminal boundary of the BoNT/B HCN
domain can be any amino acid present in the amino acid region K1076 to Y1098;
the amino acid that defines the carboxyl-terminal boundary of the BoNT/C1 HCN domain can be any amino acid present in the amino acid region N1090 to Y1112; the amino acid that defines the carboxyl-terminal boundary of the BoNT/D HCN domain can be any amino acid present in the amino acid region E1077 to Y1099; the amino acid that defines the carboxyl-terminal boundary of the BoNT/E HCN domain can be any amino acid present in the amino acid region S1064 to Y1086; the amino acid that defines the carboxyl-terminal boundary of the BoNT/F HCN domain can be any amino acid present in the amino acid region S1084 to Y1106; the amino acid that defines the carboxyl-terminal boundary of the BoNT/G HCN domain can be any amino acid present in the amino acid region W1084 to Y1106; and the amino acid that defines the carboxyl-terminal boundary of the TeNT HCN domain can be any amino acid present in the amino acid region T1106 to Y1128.
and Hcc domains) all naturally-occurring Clostridial toxins comprises a range of amino acids. In defining the boundary of the BoNT/A HCN domain as the beginning or the end of ordered secondary structure, the HCN domain could end at Q1091 of an a-helix and the Hcc domain could begin at K1109 of a(3-strand (see FIG. 7B).

Thus, minimally an amino acid that defines the carboxyl-terminal boundary of the BoNT/A HCN domain comprises can be any amino acid present in the amino acid region D1089 to Y1111. Similar analysis indicates that minimally, the amino acid that defines the carboxyl-terminal boundary of the BoNT/B HCN
domain can be any amino acid present in the amino acid region K1076 to Y1098;
the amino acid that defines the carboxyl-terminal boundary of the BoNT/C1 HCN domain can be any amino acid present in the amino acid region N1090 to Y1112; the amino acid that defines the carboxyl-terminal boundary of the BoNT/D HCN domain can be any amino acid present in the amino acid region E1077 to Y1099; the amino acid that defines the carboxyl-terminal boundary of the BoNT/E HCN domain can be any amino acid present in the amino acid region S1064 to Y1086; the amino acid that defines the carboxyl-terminal boundary of the BoNT/F HCN domain can be any amino acid present in the amino acid region S1084 to Y1106; the amino acid that defines the carboxyl-terminal boundary of the BoNT/G HCN domain can be any amino acid present in the amino acid region W1084 to Y1106; and the amino acid that defines the carboxyl-terminal boundary of the TeNT HCN domain can be any amino acid present in the amino acid region T1106 to Y1128.

[0212] Aspects of the present invention provide, in part, an altered targeting domain. As used herein, the term "altered targeting domain" means any polypeptide that can selectively bind to a non-Clostridial toxin receptor present on a non-Clostridial toxin target cell and initiate the overall internalization mechanism whereby the modified Clostridial toxin disclosed in the present specification intoxicates a target cell. As used herein, the term "selectively" means having a highly preferred activity or effect. As used herein, the term "selectively bind" means a molecule is able to bind its target receptor under physiological conditions, or in vitro conditions substantially approximating physiological conditions, to a statistically significantly greater degree relative to other, non-target receptors. Thus, with reference to an altered targeting domain of the present specification, there is a discriminatory binding of the altered targeting domain to a non-Clostridial toxin receptor presence in a non-Clostridial toxin target cell.
[0213] An altered targeting domain disclosed in the present specification facilitates the binding activity of the modified Clostridial toxins disclosed in the present specification to a non-Clostridial toxin receptor located at the surface of a Clostridial toxin target cell. As used herein, the term "binding activity" means that one molecule is directly or indirectly contacting another molecule via at least one intermolecular or intramolecular force, including, without limitation, a covalent bond, an ionic bond, a metallic bond, a hydrogen bond, a hydrophobic interaction, a van der Waals interaction, and the like, or any combination thereof. "Bound" and "bind" are considered terms for binding.
[0214] As used herein, the term "binding affinity" means how strong a molecule's binding activity is for a particular receptor. In general, high binding affinity results from greater intermolecular force between a binding domain and its receptor while low binding affinity involves less intermolecular force between the ligand and its receptor. High binding affinity involves a longer residence time for the binding domain at its receptor binding site than is the case for low binding affinity. As such, a molecule with a high binding affinity means a lower concentration of that molecule is required to maximally occupy the binding sites of a receptor and trigger a physiological response. Conversely, low binding affinity means a relatively high concentration of a molecule is required before the receptor binding sites of a receptor is maximally occupied and the maximum physiological response is achieved. Thus, modified Clostridial toxins with increased binding activity due to high binding affinity will allow administration of reduced doses of the toxin, thereby reducing or preventing unwanted side-effects associated with toxin dispersal into non-targeted areas.
[0215] As used herein, the term "binding specificity" means how specific a molecule's binding activity is one particular receptor. In general, high binding specificity results in a more exclusive interaction with one particular receptor or subgroup of receptors while low binding specificity results in a more promiscuous interaction with a larger group of receptors. As such, a molecule with a high binding specificity means that molecule will occupy the binding sites of a particular receptor and trigger a physiological response. Conversely, low binding specificity means a molecule will occupy the binding sites of a many receptors and trigger a multitude of physiological responses.
Thus, modified Clostridial toxins with increased binding activity due to high binding specificity will only target non-Clostridial toxin receptors present on a subgroup of non-Clostridial toxin target cells, thereby reducing the side effects associated with the targeting of all non-Clostridial toxin target cells.
Thus, modified Clostridial toxins with increased binding activity due to high binding specificity will only target non-Clostridial toxin receptors present on a subgroup of non-Clostridial toxin target cells, thereby reducing the side effects associated with the targeting of all non-Clostridial toxin target cells.
[0216] In addition to its altered targeting activity, replacement of a naturally-occurring targeting domain with an altered target domain disclosed in the specification has an added advantage of reducing the likelihood of the modified toxin from eliciting an immunogenic response.
Regions found in the Hcc targeting domain are bound by neutralizing anti-BoNT/A antibodies, see, e.g., M. Zouhair Atassi et al., Mapping of the Antibody-binding Regions on Botulinum Neurotoxin H-chain Domain 855-1296 with Anti-toxin Antibodies from Three Host Species, 15 J. PROT. CHEM. 691-700, (1996);

Therefore, elimination of this targeting domain will reduce the likelihood of an immunogenic response because 1) the Clostridial toxin Hcc targeting domain is absent; 2) an altered targeting domain derived from a human will most likely not elicit an immunogenic response in a patient because it is a human polypeptide.

[0221] It is recognized by those of skill in the art that there can be naturally occurring altered targeting domain variants that differ somewhat in their amino acid sequence, and also in the nucleic acids encoding these proteins. As used herein, the term "naturally occurring altered targeting domain variant" means any altered targeting domain produced by a naturally-occurring process, including, without limitation, altered targeting domain isoforms produced from alternatively-spliced transcripts, altered targeting domain isoforms produced by spontaneous mutation and altered targeting domain subtypes. A naturally occurring altered targeting domain variant can function in substantially the same manner as the reference altered targeting domain on which the naturally occurring altered targeting domain variant is based, and can be substituted for the reference altered targeting domain in any aspect of the present invention.

[0224] As used herein, the term "conservative altered targeting domain variant" means an altered targeting domain that has at least one amino acid substituted by another amino acid or an amino acid analog that has at least one property similar to that of the original amino acid from the reference altered targeting domain sequence. Examples of properties include, without limitation, similar size, topography, charge, hydrophobicity, hydrophilicity, lipophilicity, covalent-bonding capacity, hydrogen-bonding capacity, a physicochemical property, of the like, or any combination thereof. A

[0225] As used herein, the term "non-conservative altered targeting domain variant" means an altered targeting domain in which 1) at least one amino acid is deleted from the reference altered targeting domain on which the non-conservative altered targeting domain variant is based; 2) at least one amino acid added to the reference altered targeting domain on which the non-conservative altered targeting domain is based; or 3) at least one amino acid is substituted by another amino acid or an amino acid analog that does not share any property similar to that of the original amino acid from the reference altered targeting domain sequence. A non-conservative altered targeting domain variant can function in substantially the same manner as the reference altered targeting domain on which the non-conservative altered targeting domain variant is based, and can be substituted for the reference altered targeting domain in any aspect of the present invention. A non-conservative altered targeting domain variant can delete one or more amino acids, two or more amino acids, three or more amino acids, four or more amino acids, five or more amino acids, and ten or more amino acids from the reference altered targeting domain on which the non-conservative altered targeting domain variant is based. A non-conservative altered targeting domain variant can add one or more amino acids, two or more amino acids, three or more amino acids, four or more amino acids, five or more amino acids, and ten or more amino acids to the reference altered targeting domain on which the non-conservative altered targeting domain variant is based. A non-conservative altered targeting domain variant may substitute one or more amino acids, two or more amino acids, three or more amino acids, four or more amino acids, five or more amino acids, ten or more amino acids, 20 or more amino acids, 30 or more amino acids, 40 or more amino acids, 50 or more amino acids, 100 or more amino acids, 200 or more amino acids, 300 or more amino acids, 400 or more amino acids, or 500 or more amino acids from the reference altered targeting domain on which the non-conservative altered targeting domain variant is based. A non-conservative altered targeting domain variant can also substitute, e.g., at least 2 contiguous amino acids, at least 3 contiguous amino acids, at least 4 contiguous amino acids, at least 5 contiguous amino acids, at least 10 contiguous amino acids, at least 15 contiguous amino acids, at least 20 contiguous amino acids, or at least 25 contiguous amino acids from the reference altered targeting domain on which the non-conservative altered targeting domain variant is based, that possess at least 50% amino acid identity, 65% amino acid identity, 75% amino acid identity, 85% amino acid identity or 95% amino acid identity to the reference altered targeting domain on which the non-conservative altered targeting domain variant is based. Non-limiting examples of a non-conservative altered targeting domain variant include, e.g., non-conservative opioid peptide variants, non-conservative melanocortin peptide variants, non-conservative galanin variants, non-conservative granin variants, non-conservative tachykinin peptide variants, non-conservative cholecystokinin variants, non-conservative Neuropeptide Y related peptide variants, non-conservative kinin peptide variants, non-conservative PAR peptide variants, non-conservative corticotropin-releasing hormone variants, non-conservative thyrotropin-releasing hormone variants and non-conservative somatostatin variants.
[0226] As used herein, the term "altered targeting domain chimeric" means a polypeptide comprising at least a portion of an altered targeting domain and at least a portion of at least one other polypeptide to form an altered targeting domain with at least one property different from the reference altered targeting domain, with the proviso that this altered targeting domain chimeric is still capable of selectively binding to a non-Clostridial toxin receptor present on a non-Clostridial toxin target cell and initiate the overall internalization mechanism whereby a modified Clostridial toxin intoxicates a target cell.
[0227] As used herein, the term "active altered targeting domain fragment"
means any of a variety of altered targeting domain fragments can be useful in aspects of the present invention with the proviso that these active fragments are still capable of selectively binding to a non-Clostridial toxin receptor present on a non-Clostridial toxin target cell and initiate the overall internalization mechanism whereby a Clostridial toxin intoxicates a target cell. Thus, aspects of this embodiment can include altered targeting domains comprising a length of, e.g., at least 5 amino acids, at least 10 amino acids, at least 20 amino acids, at least 30 amino acids, at least 40 amino acids, at least 50 amino acids, at least 100 amino acids, at least 150 amino acids, at least 200 amino acids, at least 250 amino acids, at least 300 amino acids, at least 350 amino acids, at least 400 amino acids and at least 450 amino acids. Other aspects of this embodiment can include altered targeting domains comprising a length of, e.g., at most 5 amino acids, at most 10 amino acids, at most 20 amino acids, at most 30 amino acids, at most 40 amino acids, at most 50 amino acids, at most 100 amino acids, at most 150 amino acids, at most 200 amino acids, at most 250 amino acids, at most 300 amino acids, at most 350 amino acids, at most 400 amino acids and at most 450 amino acids.

[0228] Any of a variety of sequence alignment methods can be used to determine percent identity of naturally-occurring altered targeting domain variants and non-naturally-occurring altered targeting domain variants, including, without limitation, global methods, local methods and hybrid methods, such as, e.g., segment approach methods. Protocols to determine percent identity are routine procedures within the scope of one skilled in the art and from the teaching herein.
[0229] Thus, in an embodiment, a modified Clostridial toxin disclosed in the present specification comprises an altered targeting domain. In an aspect of this embodiment, an altered targeting domain comprises a naturally occurring altered targeting domain variant, such as, e.g., an altered targeting domain isoform or an altered targeting domain subtype. In another aspect of this embodiment, a Clostridial toxin altered targeting domain comprises a non-naturally occurring altered targeting domain variant, such as, e.g., a conservative altered targeting domain variant, a non-conservative altered targeting domain variant, an altered targeting domain chimeric, an active altered targeting domain fragment, or any combination thereof.
[0230] An example of an altered targeting domain disclosed in the present specification is, e.g., a opioid peptide, such as, e.g., an enkephalin, an endomorphin, an endorphin, a dynorphin, a nociceptin or a hemorphin. Thus, in an embodiment, an altered targeting domain is derived from an opioid peptide.

[0324] An altered targeting domain disclosed in the present specification replaces the binding activity of the Clostridial toxin targeting domain found in naturally occurring Clostridial toxins. As used herein, the term "Clostridial toxin targeting domain" is synonymous with "Clostridial toxin Hcc targeting region" or "Clostridial toxin Hcc region" and means any naturally occurring Clostridial toxin polypeptide that can execute the cell binding step of the intoxication process, including, e.g., the binding of the Clostridial toxin to a Clostridial toxin-specific receptor located on the plasma membrane surface of a target cell. It is envisioned that replacement of the binding activity can be achieved by, e.g., replacing the entire Clostridial toxin Hcc targeting domain with an altered targeting domain;
replacing a portion of a Clostridial toxin Hcc targeting domain with an altered targeting domain, with the proviso that the portion of a Clostridial toxin Hcc targeting domain remaining cannot selectively bind to its Clostridial toxin receptor;
and operably-linking an altered targeting domain to a Clostridial toxin comprising a Clostridial toxin Hcc targeting domain, with the proviso that the a Clostridial toxin Hcc targeting domain is altered so that it cannot selectively bind to its Clostridial toxin receptor.

[0325] The three-dimensional crystal structures of BoNT/A, BoNT/B and the Hc domain of TeNT indicate that the three functional domains of Clostridial neurotoxins are structurally distinct. The HEXXH
consensus motif of the light chain forms the tetrahedral zinc binding pocket of the catalytic site located in a deep cleft on the protein surface that is accessible by a channel. The structure of the HN and Hc domains consists primarily of (3-sheet topologies that are linked by a single a-helix. The cylindrical-shaped HN domain comprises two long amphipathic a-helices that resemble the coiled-coil motif found in some viral proteins. The HN domain also forms a long unstructured loop called the `translocation belt,' which wraps around a large negatively charged cleft of the light chain that blocks access of the zinc atom to the catalytic-binding pocket of active site. The Hc domain comprises two distinct structural features of roughly equal size that indicate function. The first, designated the HCN
domain, is located in the amino half of the Hc domain. The HCN domain forms a(3-barrel, jelly-roll fold. The Hcc domain is the second domain that comprises the Hc domain. This carboxyl-terminal domain comprises a modified (3-trefoil domain which forms three distinct carbohydrate binding regions that resembles the carbohydrate binding moiety found in many sugar-binding proteins, such as, e.g., serum amyloid P, sialidase, cryia, insecticidal a-endotoxin and lectins. Biochemical studies indicate that the (3-trefoil domain structure of the Hcc domain appears to mediate the binding to specific carbohydrate containing components of the Clostridial toxin receptor on the cell surface, see, e.g., Krzysztof Ginalski et al., Structure-based Sequence Alignment for the Beta-Trefoil Subdomain of the Clostridial Neurotoxin Family Provides Residue Level Information About the Putative Ganglioside Binding Site, 482(1-2) FEBS Lett.
119-124 (2000). The Hc domain tilts away from the HN domain exposing the surface loops and making them accessible for binding. No contacts occur between the light chain and the Hc domain.

[0326] Proteins containing the structural (3-trefoil domain represents a diverse group of proteins, see, e.g., C. A. Orengo et al., Protein Superfamilies and Domain Superfolds, 372 Nature 631-634 (1994). The (3-trefoil domain comprises a six-stranded (3-barrel closed off at one end by three (3-hairpin structures that exhibits a characteristic pseudo-threefold axis symmetry. The monomeric structural unit of this three-fold symmetry is referred to as the (3-trefoil fold that contains four (3-sheets organized as a pair of antiparallel (3-sheets. Dividing each of these (3-trefoil folds is a(3-hairpin turn.
Therefore, in a linear fashion, a(3-trefoil domain comprises four (3-sheets of the first (3-trefoil fold, a(3-hairpin turn, four (3-sheets of the second (3-trefoil fold, a second (3-hairpin turn four (3-sheets of the third (3-trefoil fold. Because the first hairpin turn is located between the fourth and fifth (3-sheets of the (3-trefoil domain, it is designated the (34/(35 (3-hairpin turn. Likewise, since the second hairpin turn is located between the eight and ninth (3-sheets of the (3-trefoil domain, it is designated the (38/(39 (3-hairpin turn.
Therefore, in a linear fashion, a(3-trefoil domain comprises four (3-sheets of the first (3-trefoil fold, a(3-hairpin turn, four (3-sheets of the second (3-trefoil fold, a second (3-hairpin turn four (3-sheets of the third (3-trefoil fold. Because the first hairpin turn is located between the fourth and fifth (3-sheets of the (3-trefoil domain, it is designated the (34/(35 (3-hairpin turn. Likewise, since the second hairpin turn is located between the eight and ninth (3-sheets of the (3-trefoil domain, it is designated the (38/(39 (3-hairpin turn.
[0327] As is typical for proteins containing a(3-trefoil fold, the overall amino acid sequence identity of the Hcc domain between Clostridial toxins is low. However, key residues essential for binding activity have been identified by structural analysis and mutagenesis experiments, see, e.g., Krzysztof Ginalski et al., Structure-based Sequence Alignment for the Beta-Trefoil Subdomain of the Clostridial Neurotoxin Family Provides Residue Level Information About the Putative Ganglioside Binding Site, 482(1-2) FEBS Lett.

Microbiol. 631-643 (2004). Additionally, research has elucidated that (34/(35 and (38/(39 (3-hairpin turns are important in conferring the proper pseudo-threefold axis symmetry observed in the (3-trefoil domain and that these turns are important for (3-trefoil domain stability, see, e.g., Stephen R. Brych et al., Structure and Stability Effects of Mutations Designed to Increase the Primary Sequence Symmetry Within the Core Region of aP-trefoil, 10 Protein Sci. 2587-2599 (2001); Jaewon Kim et al., Alternative Type l and 1' Turn Conformations in the P81P9 P-hairpin of Human Acidic Fibroblast Growth Factor, 11 Protein Sci. 459-466 (2002); Jaewon Kim et al., Sequence swapping Does Not Result in Conformation Swapping for the P41P5 and P81P9 P-hairpin Turns in Human Acidic Fibroblast Growth Factor, 14 Protein Sci. 351-359 (2005).

[0335] In is envisioned that any and all protease cleavage sites can be used to convert the single-chain polypeptide form of a Clostridial toxin into the di-chain form, including, without limitation, endogenous di-chain loop protease cleavage sites and exogenous protease cleavage sites. The location and kind of protease cleavage site may be critical because certain targeting domains require a free amino-terminal or carboxyl-terminal amino acid. For example, when a targeting domain is placed between two other domains, e.g., see FIG. 5, a criteria for selection of a protease cleavage site could be whether the protease that cleaves its site leaves a flush cut, exposing the free amino-terminal or carboxyl-terminal of the altered targeting domain necessary for selective binding of the targeting domain to its receptor. The selection and placement of a protease cleavage site is well known in the art.
[0336] As used herein, the term "endogenous di-chain loop protease cleavage site" is synonymous with a "naturally occurring di-chain loop protease cleavage site" and means a naturally occurring protease cleavage site found within the di-chain loop region of a naturally occurring Clostridial toxin and includes, without limitation, naturally occurring Clostridial toxin di-chain loop protease cleavage site variants, such as, e.g., Clostridial toxin di-chain loop protease cleavage site isoforms and Clostridial toxin di-chain loop protease cleavage site subtypes. Non-limiting examples of an endogenous protease cleavage site, include, e.g., a BoNT/A di-chain loop protease cleavage site, a BoNT/B di-chain loop protease cleavage site, a BoNT/C1 di-chain loop protease cleavage site, a BoNT/D di-chain loop protease cleavage site, a BoNT/E di-chain loop protease cleavage site, a BoNT/F di-chain loop protease cleavage site, a BoNT/G
di-chain loop protease cleavage site and a TeNT di-chain loop protease cleavage site.
di-chain loop protease cleavage site and a TeNT di-chain loop protease cleavage site.
[0337] As mentioned above, Clostridial toxins are translated as a single-chain polypeptide of approximately 150 kDa that is subsequently cleaved by proteolytic scission within a disulfide loop by a naturally-occurring protease. This posttranslational processing yields a di-chain molecule comprising an approximately 50 kDa light chain (LC) and an approximately 100 kDa heavy chain (HC) held together by a single disulphide bond and noncovalent interactions. While the identity of the protease is currently unknown, the di-chain loop protease cleavage site for many Clostridial toxins has been proposed. In BoNTs, cleavage at K448-A449 converts the single polypeptide form of BoNT/A
into the di-chain form;
cleavage at K441-A442 converts the single polypeptide form of BoNT/B into the di-chain form; cleavage at K449-T450 converts the single polypeptide form of BoNT/C1 into the di-chain form; cleavage at R445-D446 converts the single polypeptide form of BoNT/D into the di-chain form;
cleavage at R422-K423 converts the single polypeptide form of BoNT/E into the di-chain form;
cleavage at K439-A440 converts the single polypeptide form of BoNT/F into the di-chain form; and cleavage at K446-S447 converts the single polypeptide form of BoNT/G into the di-chain form. Proteolytic cleavage of the single polypeptide form of TeNT at A457-S458 results in the di-chain form. Such a di-chain loop protease cleavage site is operably-linked in-frame to a modified Clostridial toxin as a fusion protein.
into the di-chain form;
cleavage at K441-A442 converts the single polypeptide form of BoNT/B into the di-chain form; cleavage at K449-T450 converts the single polypeptide form of BoNT/C1 into the di-chain form; cleavage at R445-D446 converts the single polypeptide form of BoNT/D into the di-chain form;
cleavage at R422-K423 converts the single polypeptide form of BoNT/E into the di-chain form;
cleavage at K439-A440 converts the single polypeptide form of BoNT/F into the di-chain form; and cleavage at K446-S447 converts the single polypeptide form of BoNT/G into the di-chain form. Proteolytic cleavage of the single polypeptide form of TeNT at A457-S458 results in the di-chain form. Such a di-chain loop protease cleavage site is operably-linked in-frame to a modified Clostridial toxin as a fusion protein.
[0338] However, it should also be noted that additional cleavage sites within the di-chain loop also appear to be cleaved resulting in the generation of a small peptide fragment being lost. As a non-limiting example, BoNT/A single-chain polypeptide cleave ultimately results in the loss of a ten amino acid fragment within the di-chain loop. Thus, in BoNTs, cleavage at S441-L442 converts the single polypeptide form of BoNT/A into the di-chain form; cleavage at G444-1445 converts the single polypeptide form of BoNT/B into the di-chain form; cleavage at S445-L446 converts the single polypeptide form of BoNT/C1 into the di-chain form; cleavage at K442-N443 converts the single polypeptide form of BoNT/D
into the di-chain form; cleavage at K419-G420 converts the single polypeptide form of BoNT/E into the di-chain form; cleavage at K423-S424 converts the single polypeptide form of BoNT/E into the di-chain form;
cleavage at K436-G437 converts the single polypeptide form of BoNT/F into the di-chain form; cleavage at T444-G445 converts the single polypeptide form of BoNT/G into the di-chain form; and cleavage at E448-Q449 converts the single polypeptide form of BoNT/G into the di-chain form.
into the di-chain form; cleavage at K419-G420 converts the single polypeptide form of BoNT/E into the di-chain form; cleavage at K423-S424 converts the single polypeptide form of BoNT/E into the di-chain form;
cleavage at K436-G437 converts the single polypeptide form of BoNT/F into the di-chain form; cleavage at T444-G445 converts the single polypeptide form of BoNT/G into the di-chain form; and cleavage at E448-Q449 converts the single polypeptide form of BoNT/G into the di-chain form.
[0339] Thus, in an embodiment, a protease cleavage site comprising an endogenous Clostridial toxin di-chain loop protease cleavage site is used to convert the single-chain toxin into the di-chain form. In aspects of this embodiment, conversion into the di-chain form by proteolytic cleavage occurs from a site comprising, e.g., a BoNT/A di-chain loop protease cleavage site, a BoNT/B di-chain loop protease cleavage site, a BoNT/C1 di-chain loop protease cleavage site, a BoNT/D di-chain loop protease cleavage site, a BoNT/E di-chain loop protease cleavage site, a BoNT/F di-chain loop protease cleavage site, a BoNT/G di-chain loop protease cleavage site or a TeNT di-chain loop protease cleavage site.
[0340] In other aspects of this embodiment, conversion into the di-chain form by proteolytic cleavage occurs from a site comprising, e.g., a di-chain loop region of BoNT/A
comprising amino acids 430-454 of SEQ ID NO: 1; a di-chain loop region of BoNT/B comprising amino acids 437-446 of SEQ ID NO: 2; a di-chain loop region of BoNT/C1 comprising amino acids 437-453 of SEQ ID NO: 3; a di-chain loop region of BoNT/D comprising amino acids 437-450 of SEQ ID NO: 4; a di-chain loop region of BoNT/E comprising amino acids 412-426 of SEQ ID NO: 5; a di-chain loop region of BoNT/F
comprising amino acids 429-445 of SEQ ID NO: 6; a di-chain loop region of BoNT/G comprising amino acids 436-450 of SEQ ID NO: 7; or a di-chain loop region of TeNT comprising amino acids 439-467 of SEQ ID NO: 8.
comprising amino acids 430-454 of SEQ ID NO: 1; a di-chain loop region of BoNT/B comprising amino acids 437-446 of SEQ ID NO: 2; a di-chain loop region of BoNT/C1 comprising amino acids 437-453 of SEQ ID NO: 3; a di-chain loop region of BoNT/D comprising amino acids 437-450 of SEQ ID NO: 4; a di-chain loop region of BoNT/E comprising amino acids 412-426 of SEQ ID NO: 5; a di-chain loop region of BoNT/F

[0341] It is also envisioned that an exogenous protease cleavage site can be used to convert the single-chain polypeptide form of a modified Clostridial toxin disclosed in the present specification into the di-chain form. As used herein, the term "exogenous protease cleavage site" is synonymous with a "non-naturally occurring protease cleavage site" and means a protease cleavage site that is not normally present in a di-chain loop region from a naturally occurring Clostridial toxin. Non-limiting examples of exogenous protease cleavage sites include, e.g., an enterokinase cleavage site (Table 4); a Thrombin cleavage site (Table 4); a Factor Xa cleavage site (Table 4); a human rhinovirus 3C protease cleavage site (Table 4); a tobacco etch virus (TEV) protease cleavage site (Table 4); a dipeptidyl aminopeptidase cleavage site; a small ubiquitin-like modifier (SUMO)/ubiquitin-like protein-1(ULP-1) protease cleavage site, such as, e.g., MADSEVNQEAKPEVKPEVKPETHINLKVSDGSSEIFFKIKKTTPLRRLMEAFAKRQGK
EMDSLRFLYDGIRIQADQTPEDLDMEDNDIIEAHREQIGG (SEQ ID. NO: 142); and a Clostridial toxin substrate cleavage site.
EMDSLRFLYDGIRIQADQTPEDLDMEDNDIIEAHREQIGG (SEQ ID. NO: 142); and a Clostridial toxin substrate cleavage site.
[0342] As mentioned above, a Clostridial toxin is converted from a single polypeptide form into a di-chain molecule by proteolytic cleavage. While the naturally-occurring protease is currently not known, cleavage occurs within the di-chain loop region between the two cysteine residues that form the disulfide bridge (see Table 3). Replacement of an endogenous protease cleavage site with an exogenous protease cleavage site will enable cleavage of a modified Clostridial toxin disclosed in the present specification when expressed in an organism that does not produce the naturally-occurring protease used to cleave the di-chain loop region of a toxin. Similarly, an addition of an exogenous protease cleavage site in the di-chain loop region will also enable cleavage of a modified Clostridial toxin disclosed in the present specification when expressed in an organism that does not produce the naturally-occurring protease used to cleave the di-chain loop region of a toxin.

[0343] It is envisioned that an exogenous protease cleavage site of any and all lengths can be useful in aspects of the present invention with the proviso that the exogenous protease cleavage site is capable of being cleaved by its respective protease. Thus, in aspects of this embodiment, an exogenous protease cleavage site can be, e.g., at least 6 amino acids in length, at least 7 amino acids in length, at least 8 amino acids in length, at least 9 amino acids in length, at least 10 amino acids in length, at least 15 amino acids in length, at least 20 amino acids in length, at least 25 amino acids in length, at least 30 amino acids in length, at least 40 amino acids in length, at least 50 amino acids in length or at least 60 amino acids in length. In other aspects of this embodiment, an exogenous protease cleavage site can be, e.g., at most 6 amino acids in length, at most 7 amino acids in length, at most 8 amino acids in length, at most 9 amino acids in length, at most 10 amino acids in length, at most 15 amino acids in length, at most 20 amino acids in length, at most 25 amino acids in length, at most 30 amino acids in length, at most 40 amino acids in length, at most 50 amino acids in length or at most 60 amino acids in length.
[0344] In aspects of this embodiment, a di-chain loop region can be modified to substitute a naturally-occurring protease cleavage site for an exogenous protease cleavage site. In this type of modification, the naturally-occurring protease cleavage site is made inoperable and thus can not be cleaved by its protease. Only the exogenous protease cleavage site can be cleaved by its corresponding exogenous protease. In this type of modification, the exogenous protease site is operably-linked in-frame to a modified Clostridial toxin as a fusion protein and the site can be cleaved by its respective exogenous protease. As a non-limiting example, a single-chain modified BoNT/A comprising an exogenous protease cleavage site in the di-chain loop region can be cleaved by its respective exogenous protease to produce the di-chain form of the toxin.
[0345] In other aspects of this embodiment, a di-chain loop region can be modified to include an exogenous protease cleavage site in addition to the naturally-occurring protease cleavage site. In this type of modification, both cleavage sites are operably-linked in-frame to a modified Clostridial toxin as a fusion protein and both sites can be cleaved by their respective proteases. As a non-limiting example, a single-chain modified BoNT/A that comprises a di-chain loop containing both the naturally-occurring BoNT/A di-chain loop protease cleavage site and an exogenous protease cleavage site can be cleaved by either the naturally occurring di-chain loop protease or by the appropriate exogenous protease to produce the di-chain form of the toxin.
[0346] A naturally-occurring protease cleavage site can be made inoperable by altering at least the two amino acids flanking the peptide bond cleaved by the naturally-occurring di-chain loop protease. More extensive alterations can be made, with the proviso that the two cysteine residues of the di-chain loop region remain intact and can still form the disulfide bridge. Non-limiting examples of an amino acid alteration include deletion of an amino acid or replacement of the original amino acid with a different amino acid. Thus, in one embodiment, a naturally-occurring protease cleavage site is made inoperable by altering the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease. In other aspects of this embodiment, a naturally-occurring protease cleavage site is made inoperable by altering, e.g., at least three amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at least four amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at least five amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at least six amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at least seven amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at least eight amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at least nine amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at least ten amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at least 15 amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease;
or at least 20 amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease.
or at least 20 amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease.
[0347] In still other aspects of this embodiment, a naturally-occurring di-chain protease cleavage site is made inoperable by altering, e.g., at most three amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at most four amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at most five amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at most six amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at most seven amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at most eight amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at most nine amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at most ten amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; at most 15 amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease; or at most 20 amino acids including the two amino acids flanking the peptide bond cleaved by a naturally-occurring protease.
[0348] In an embodiment, an exogenous protease cleavage site is located within the di-chain loop of a modified Clostridial toxin. In aspects of this embodiment, a modified Clostridial toxin comprises an exogenous protease cleavage site comprises, e.g., a bovine enterokinase protease cleavage site, a Tobacco Etch Virus protease cleavage site, a Human Rhinovirus 3C protease cleavage site, a SUMO/ULP-1 protease cleavage site, a Thrombin protease cleavage site or a Factor Xa protease cleavage site. In other aspects of this embodiment, an exogenous protease cleavage site is located within the di-chain loop of, e.g., a modified BoNT/A, a modified BoNT/B, a modified BoNT/C1, a modified BoNT/D, a modified BoNT/E, a modified BoNT/F, a modified BoNT/G or a modified TeNT.

[0356] It is understood that a modified Clostridial toxin disclosed in the present specification can optionally include one or more additional components. As a non-limiting example of an optional component, a modified Clostridial toxin can further comprise a flexible region comprising a flexible spacer.
Non-limiting examples of a flexible spacer include, e.g., a G-spacer GGGGS
(SEQ ID NO: 160) or an A-spacer EAAAK (SEQ ID NO: 161). A flexible region comprising flexible spacers can be used to adjust the length of a polypeptide region in order to optimize a characteristic, attribute or property of a polypeptide.
Such a flexible region is operably-linked in-frame to the modified Clostridial toxin as a fusion protein. As a non-limiting example, a polypeptide region comprising one or more flexible spacers in tandem can be use to better expose a protease cleavage site thereby facilitating cleavage of that site by a protease. As another non-limiting example, a polypeptide region comprising one or more flexible spacers in tandem can be use to better present an altered targeting domain, thereby facilitating the binding of that altered targeting domain to its receptor.
Non-limiting examples of a flexible spacer include, e.g., a G-spacer GGGGS
(SEQ ID NO: 160) or an A-spacer EAAAK (SEQ ID NO: 161). A flexible region comprising flexible spacers can be used to adjust the length of a polypeptide region in order to optimize a characteristic, attribute or property of a polypeptide.

In another embodiment, a modified Clostridial toxin disclosed in the present specification can further comprise flexible region comprising a plurality of flexible spacers in tandem. In aspects of this embodiment, a flexible region can comprise in tandem, e.g., at least 1 G-spacer, at least 2 G-spacers, at least 3 G-spacers, at least 4 G-spacers or at least 5 G-spacers. In other aspects of this embodiment, a flexible region can comprise in tandem, e.g., at most 1 G-spacer, at most 2 G-spacers, at most 3 G-spacers, at most 4 G-spacers or at most 5 G-spacers.

In still other aspects of this embodiment, a flexible region can comprise in tandem, e.g., at most 1 A-spacer, at most 2 A-spacers, at most 3 A-spacers, at most 4 A-spacers or at most 5 A-spacers. In another aspect of this embodiment, a modified Clostridial toxin can comprise a flexible region comprising one or more copies of the same flexible spacers, one or more copies of different flexible-spacer regions, or any combination thereof.
[0358] In aspects of this embodiment, a modified Clostridial toxin comprising a flexible spacer can be, e.g., a modified BoNT/A, a modified BoNT/B, a modified BoNT/C1, a modified BoNT/D, a modified BoNT/E, a modified BoNT/F, a modified BoNT/G or a modified TeNT.
[0359] It is envisioned that a modified Clostridial toxin disclosed in the present specification can comprise a flexible spacer in any and all locations with the proviso that modified Clostridial toxin is capable of performing the intoxication process. In aspects of this embodiment, a flexible spacer is positioned between, e.g., an enzymatic domain and a translocation domain, an enzymatic domain and an altered targeting domain, an enzymatic domain and a protease cleavage site. In other aspects of this embodiment, a G-spacer is positioned between, e.g., an enzymatic domain and a translocation domain, an enzymatic domain and an altered targeting domain, an enzymatic domain and a protease cleavage site. In other aspects of this embodiment, a A-spacer is positioned between, e.g., an enzymatic domain and a translocation domain, an enzymatic domain and an altered targeting domain, an enzymatic domain and a protease cleavage site.

[0362] As another non-limiting example of an optional component, a modified Clostridial toxin can further comprise an epitope-binding region. An epitope-binding region can be used in a wide variety of procedures involving, e.g., protein purification and protein visualization.
Such an epitope-binding region is operably-linked in-frame to a modified Clostridial toxin as a fusion protein. Non-limiting examples of an epitope-binding region include, e.g., FLAG, ExpressTM (SEQ ID NO: 162), human Influenza virus hemagluttinin (HA) (SEQ ID NO: 163), human p62 -"'y protein (c-MYC) (SEQ ID

Non-limiting examples of specific protocols for selecting, making and using an appropriate binding peptide are described in, e.g., Epitope Tagging, pp. 17.90-17.93 (Sambrook and Russell, eds., Molecular Cloning A

[0363] Thus, in an embodiment, a modified Clostridial toxin disclosed in the present specification can further comprise an epitope-binding region. In another embodiment, a modified Clostridial toxin disclosed in the present specification can further comprises a plurality of epitope-binding regions. In aspects of this embodiment, a modified Clostridial toxin can comprise, e.g., at least 1 epitope-binding region, at least 2 epitope-binding regions, at least 3 epitope-binding regions, at least 4 epitope-binding regions or at least 5 epitope-binding regions. In other aspects of this embodiment, a modified Clostridial toxin can comprise, e.g., at most 1 epitope-binding region, at most 2 epitope-binding regions, at most 3 epitope-binding regions, at most 4 epitope-binding regions or at most 5 epitope-binding regions. In another aspect of this embodiment, a modified Clostridial toxin can comprise one or more copies of the same epitope-binding region, one or more copies of different epitope-binding regions, or any combination thereof.
[0364] The location of an epitope-binding region can be in various positions, including, without limitation, at the amino terminus of a modified Clostridial toxin, within a modified Clostridial toxin, or at the carboxyl terminus of a modified Clostridial toxin. Thus, in an embodiment, an epitope-binding region is located at the amino-terminus of a modified Clostridial toxin. In such a location, a start methionine should be placed in front of the epitope-binding region. In addition, it is known in the art that when adding a polypeptide that is operably-linked to the amino terminus of another polypeptide comprising the start methionine that the original methionine residue can be deleted. This is due to the fact that the added polypeptide will contain a new start methionine and that the original start methionine may reduce optimal expression of the fusion protein. In aspects of this embodiment, an epitope-binding region located at the amino-terminus of a modified Clostridial toxin disclosed in the present specification can be, e.g., a FLAG, ExpressTM epitope-binding region, a human Influenza virus hemagluttinin (HA) epitope-binding region, a human p62 -"'y protein (c-MYC) epitope-binding region, a Vesicular Stomatitis Virus Glycoprotein (VSV-G) epitope-binding region, a Substance P epitope-binding region, a glycoprotein-D precursor of Herpes simplex virus (HSV) epitope-binding region, a V5 epitope-binding region, a AU1 epitope-binding region, a AU5 epitope-binding region, a polyhistidine epitope-binding region, a streptavidin binding peptide epitope-binding region, a biotin epitope-binding region, a biotinylation epitope-binding region, a glutathione binding domain of glutathione-S-transferase, a calmodulin binding domain of the calmodulin binding protein or a maltose binding domain of the maltose binding protein.
[0365] In another embodiment, an epitope-binding region is located at the carboxyl-terminus of a modified Clostridial toxin. In aspects of this embodiment, an epitope-binding region located at the carboxyl-terminus of a modified Clostridial toxin disclosed in the present specification can be, e.g., a FLAG, ExpressTM epitope-binding region, a human Influenza virus hemagluttinin (HA) epitope-binding region, a human p62 -"'y protein (c-MYC) epitope-binding region, a Vesicular Stomatitis Virus Glycoprotein (VSV-G) epitope-binding region, a Substance P epitope-binding region, a glycoprotein-D

precursor of Herpes simplex virus (HSV) epitope-binding region, a V5 epitope-binding region, a AU1 epitope-binding region, a AU5 epitope-binding region, a polyhistidine epitope-binding region, a streptavidin binding peptide epitope-binding region, a biotin epitope-binding region, a biotinylation epitope-binding region, a glutathione binding domain of glutathione-S-transferase, a calmodulin binding domain of the calmodulin binding protein or a maltose binding domain of the maltose binding protein.
[0366] It is envisioned that a modified Clostridial toxin disclosed in the present specification can comprise an altered targeting domain in any and all locations with the proviso that modified Clostridial toxin is capable of performing the intoxication process. Non-limiting examples include, locating an enhance targeting domain at the amino terminus of a modified Clostridial toxin (see FIG. 4); locating an enhance targeting domain between a Clostridial toxin enzymatic domain and a Clostridial toxin translocation domain of a modified Clostridial toxin (see FIG. 5); and locating an enhance targeting domain at the carboxyl terminus of a modified Clostridial toxin (see FIG. 6).
The enzymatic domain of naturally-occurring Clostridial toxins contains the native start methionine.
Thus, in domain organizations where the enzymatic domain is not in the amino-terminal location an amino acid sequence comprising the start methionine should be placed in front of the amino-terminal domain.
Likewise, where the altered targeting domain is in the amino-terminal position, an amino acid sequence comprising a start methionine and a protease cleavage site may be operably-linked in situations in which the altered targeting domain requires a free amino terminus, see, e.g., Shengwen Li et al., Degradable Clostridial Toxins, International Patent Application Publication WO 2006/026780 (Mar. 9, 2006). In addition, it is known in the art that when adding a polypeptide that is operably-linked to the amino terminus of another polypeptide comprising the start methionine that the original methionine residue can be deleted.

[0372] Aspects of the present invention provide, in part modified Clostridial toxins. Non-limiting examples of Clostridial toxin modifications disclosed in the present specification include, e.g., addition of an altered targeting domain, addition of a protease cleavage site, rearrangement of the enzymatic, translocation and binding domains and addition of a spacer region. It is understood that all such modifications do not substantially affect the ability of a modified Clostridial toxin to intoxicate a cell. As used herein, the term "do not substantially affect" means a modified Clostridial toxin can still execute the overall cellular mechanism whereby a Clostridial toxin enters a neuron and inhibits neurotransmitter release and encompasses the binding of a Clostridial toxin to a low or high affinity receptor complex, the internalization of the toxin/receptor complex, the translocation of the Clostridial toxin light chain into the cytoplasm and the enzymatic modification of a Clostridial toxin substrate.

In aspects of this embodiment, the modified Clostridial toxin is, e.g., at most 10% as toxic as a naturally-occurring Clostridial toxin, at most 20% as toxic as a naturally-occurring Clostridial toxin, at most 30% as toxic as a naturally-occurring Clostridial toxin, at most 40% as toxic as a naturally-occurring Clostridial toxin, at most 50% as toxic as a naturally-occurring Clostridial toxin, at most 60% as toxic as a naturally-occurring Clostridial toxin, at most 70% as toxic as a naturally-occurring Clostridial toxin, at most 80% as toxic as a naturally-occurring Clostridial toxin, at most 90% as toxic as a naturally-occurring Clostridial toxin or at most 95% as toxic as a naturally-occurring Clostridial toxin.

[0388] The methods disclosed in the present specification include, in part, introducing into a cell a polynucleotide molecule. A polynucleotide molecule introduced into a cell can be transiently or stably maintained by that cell. Stably-maintained polynucleotide molecules may be extra-chromosomal and replicate autonomously, or they may be integrated into the chromosomal material of the cell and replicate non-autonomously. It is envisioned that any and all methods for introducing a polynucleotide molecule disclosed in the present specification into a cell can be used. Methods useful for introducing a nucleic acid molecule into a cell include, without limitation, chemical-mediated transfection such as, e.g., calcium phosphate-mediated, diethyl-aminoethyl (DEAE) dextran-mediated, lipid-mediated, polyethyleneimine (PEI)-mediated, polylysine-mediated and polybrene-mediated; physical-mediated tranfection, such as, e.g., biolistic particle delivery, microinjection, protoplast fusion and electroporation; and viral-mediated transfection, such as, e.g., retroviral-mediated transfection, see, e.g., Introducing Cloned Genes into Cultured Mammalian Cells, pp. 16.1-16.62 (Sambrook & Russell, eds., Molecular Cloning A Laboratory Manual, Vol. 3, 3~d ed. 2001). One skilled in the art understands that selection of a specific method to introduce an expression construct into a cell will depend, in part, on whether the cell will transiently contain an expression construct or whether the cell will stably contain an expression construct. These protocols are routine procedures within the scope of one skilled in the art and from the teaching herein.
[0389] In an aspect of this embodiment, a chemical-mediated method, termed transfection, is used to introduce a polynucleotide molecule encoding a modified Clostridial toxin into a cell. In chemical-mediated methods of transfection the chemical reagent forms a complex with the nucleic acid that facilitates its uptake into the cells. Such chemical reagents include, without limitation, calcium phosphate-mediated, see, e.g., Martin Jordan & Florian Worm, Transfection of adherent and suspended cells by calcium phosphate, 33(2) Methods 136-143 (2004); diethyl-aminoethyl (DEAE) dextran-mediated, lipid-mediated, cationic polymer-mediated like polyethyleneimine (PEI)-mediated and polylysine-mediated and polybrene-mediated, see, e.g., Chun Zhang et al., Polyethylenimine strategies for plasmid delivery to brain-derived cells, 33(2) Methods 144-150 (2004). Such chemical-mediated delivery systems can be prepared by standard methods and are commercially available, see, e.g., CellPhect Transfection Kit (Amersham Biosciences, Piscataway, NJ); Mammalian Transfection Kit, Calcium phosphate and DEAE
Dextran, (Stratagene, Inc., La Jolla, CA); LipofectamineTM Transfection Reagent (Invitrogen, Inc., Carlsbad, CA); ExGen 500 Transfection kit (Fermentas, Inc., Hanover, MD), and SuperFect and Effectene Transfection Kits (Qiagen, Inc., Valencia, CA).

[0390] In another aspect of this embodiment, a physical-mediated method is used to introduce a polynucleotide molecule encoding a modified Clostridial toxin into a cell.
Physical techniques include, without limitation, electroporation, biolistic and microinjection. Biolistics and microinjection techniques perforate the cell wall in order to introduce the nucleic acid molecule into the cell, see, e.g., Jeike E.
Biewenga et al., Plasmid-mediated gene transfer in neurons using the biolistics technique, 71(1) J.

Electroporation, also termed electropermeabilization, uses brief, high-voltage, electrical pulses to create transient pores in the membrane through which the nucleic acid molecules enter and can be used effectively for stable and transient transfections of all cell types, see, e.g., M. Golzio et al., In vitro and in vivo electric field-mediated permeabilization, gene transfer, and expression, 33(2) Methods 126-135 (2004); and Oliver Greschet al., New non-viral method for gene transfer into primary cells, 33(2) Methods 151-163 (2004).

[0391] In another aspect of this embodiment, a viral-mediated method, termed transduction, is used to introduce a polynucleotide molecule encoding a modified Clostridial toxin into a cell. In viral-mediated methods of transient transduction, the process by which viral particles infect and replicate in a host cell has been manipulated in order to use this mechanism to introduce a nucleic acid molecule into the cell.
Viral-mediated methods have been developed from a wide variety of viruses including, without limitation, retroviruses, adenoviruses, adeno-associated viruses, herpes simplex viruses, picornaviruses, alphaviruses and baculoviruses, see, e.g., Armin Blesch, Lentiviral and MLV

[0392] Adenoviruses, which are non-enveloped, double-stranded DNA viruses, are often selected for mammalian cell transduction because adenoviruses handle relatively large polynucleotide molecules of about 36 kb, are produced at high titer, and can efficiently infect a wide variety of both dividing and non-dividing cells, see, e.g., Wim T. J. M. C. Hermens et al., Transient gene transfer to neurons and glia:
analysis of adenoviral vector performance in the CNS and PNS, 71(1) J.
Neurosci. Methods 85-98 (1997);
and Hiroyuki Mizuguchi et al., Approaches for generating recombinant adenovirus vectors, 52(3) Adv.
Drug Deliv. Rev. 165-176 (2001). Transduction using adenoviral-based system do not support prolonged protein expression because the nucleic acid molecule is carried from an episome in the cell nucleus, rather than being integrated into the host cell chromosome. Adenoviral vector systems and specific protocols for how to use such vectors are disclosed in, e.g., ViraPowerTM

[0393] Nucleic acid molecule delivery can also use single-stranded RNA
retroviruses, such as, e.g., oncoretroviruses and lentiviruses. Retroviral-mediated transduction often produce transduction efficiencies close to 100%, can easily control the proviral copy number by varying the multiplicity of infection (MOI), and can be used to either transiently or stably transduce cells, see, e.g., Tiziana Tonini et al., Transient production of retroviral- and lentiviral-based vectors for the transduction of Mammalian cells, 285 Methods Mol. Biol. 141-148 (2004); Armin Blesch, Lentiviral and MLV based retroviral vectors for ex vivo and in vivo gene transfer, 33(2) Methods 164-172 (2004); Felix Recillas-Targa, Gene transfer and expression in mammalian cell lines and transgenic animals, 267 Methods Mol.
Biol. 417-433 (2004); and Roland Wolkowicz et al., Lentiviral vectors for the delivery of DNA into mammalian cells, 246 Methods Mol. Biol. 391-411 (2004). Retroviral particles consist of an RNA genome packaged in a protein capsid, surrounded by a lipid envelope. The retrovirus infects a host cell by injecting its RNA into the cytoplasm along with the reverse transcriptase enzyme. The RNA template is then reverse transcribed into a linear, double stranded cDNA that replicates itself by integrating into the host cell genome. Viral particles are spread both vertically (from parent cell to daughter cells via the provirus) as well as horizontally (from cell to cell via virions). This replication strategy enables long-term persistent expression since the nucleic acid molecules of interest are stably integrated into a chromosome of the host cell, thereby enabling long-term expression of the protein. For instance, animal studies have shown that lentiviral vectors injected into a variety of tissues produced sustained protein expression for more than 1 year, see, e.g., Luigi Naldini et al., In vivo gene delivery and stable transduction of non-dividing cells by a lentiviral vector, 272(5259) Science 263-267 (1996). The Oncoretroviruses-derived vector systems, such as, e.g., Moloney murine leukemia virus (MoMLV), are widely used and infect many different non-dividing cells.
Lentiviruses can also infect many different cell types, including dividing and non-dividing cells and possess complex envelope proteins, which allows for highly specific cellular targeting.

This insert will be subcloned using a T4 DNA ligase procedure into a pET29 vector that is digested with appropriate restriction endonucleases to yield pET29/BoNT/A-CP5A-Nociceptin. The ligation mixture will be transformed into chemically competent E. coli DH5a cells (Invitrogen, Inc, Carlsbad, CA) using a heat shock method, will be plated on 1.5% Luria-Bertani agar plates (pH 7.0) containing 50 pg/mL of Kanamycin, and will be placed in a 37 C incubator for overnight growth.
