Description
New Zealand Paient Spedficaiion for Paient Number 501 873
MAMMALIAN NEURO-GROWTH FACTOR- LIKE PROTEIN
BACKGROUND OF THE INVENTION
Proliferation and differentiation of cells of 10 multicellular organisms are controlled by hormones and polypeptide growth factors. These diffusable molecules allow cells to communicate with each other and act in concert to form cells and organs, and to repair and regenerate damaged tissue. Examples of hormones and 15 growth factors include the steroid hormones {e.g.
estrogen, testosterone), parathyroid hormone, follicle stimulating hormone, the interleukins, platelet derived growth factor (PDGF), epidermal growth factor (EGF), granulocyte-macrophage colony stimulating factor (GM-CSF), 20 erythropoietin (EPO) and calcitonin.
Hormones and growth factors influence cellular metabolism by binding to proteins. Proteins may be integral membrane proteins that are linked to signaling 25 pathways within the cell, such as second messenger systems. Other classes of proteins are soluble molecules, such as the transcription factors.
SUMMARY OF THE INVENTION
The present invention addresses this need by providing a novel neuro-growth factor like polypeptide called Zneul and related compositions and methods. Within one aspect, the present invention provides an isolated 35 polynucleotide encoding a mammalian polypeptide termed
Zneul. The mature human Zneul polypeptide is comprised of a sequence of amino acids approximately 254 amino acids
Printed from Mimosa
long. Amino acid residue 20 of SEQ ID NO: 2, a threonine, is the initial amino acid of the mature polypeptide. Thus, it is believed that amino residues 1-19 comprise a signal sequence, and the mature Zneul polypeptide is represented 5 by the amino acid sequence comprised of residues 20-254. The mature Zneul polypeptide is further represented by SEQ ID NO: 3. Mouse Zneul is defined by SEQ ID NOs.-18 and 19. Having a signal sequence of amino acid residues 1-23, and the mature mouse Zneul is from 24-278 represented by SEQ 10 ID NO: 24. Within an additional embodiment, the polypeptide further comprises an affinity tag. Within a further embodiment, the polynucleotide is DNA.
Within a second aspect of the invention there is 15 provided an expression vector comprising (a) a transcription promoter; (b) a DNA segment encoding Zneul polypeptide, and (c) a transcription terminator, wherein the promoter, DNA segment, and terminator are operably linked.
Within a third aspect of the invention there is provided a cultured eukaryotic cell into which has been introduced an expression vector as disclosed above,
wherein said cell expresses a protein polypeptide encoded 25 by the DNA segment.
Within a further aspect of the invention there is provided a chimeric polypeptide consisting essentially of a first portion and a second portion joined by a 3 0 peptide bond. The first portion of the chimeric polypeptide consists essentially of (a) a Zneul polypeptide as shown in SEQ ID NO: 2 (b) allelic variants of SEQ ID NO:2; and (c) protein polypeptides that are at least 90% identical to (a) or (b). The second portion of 35 the chimeric polypeptide consists essentially of another polypeptide such as an affinity tag. Within one
Printed from Mimosa

embodiment the affinity tag is an immunoglobulin Fc polypeptide. The invention also provides expression vectors encoding the chimeric polypeptides and host cells transfected to produce the chimeric polypeptides.
Within an additional aspect of the invention there is provided an antibody that specifically binds to a Zneul polypeptide as disclosed above, and also an antiidiotype antibody which neutralizes the antibody to a 10 Zneul polypeptide.
In addition to the above, the present invention is also directed domains of the polypeptide including SEQ ID NOs:8, 9, 10, 11, 12, 13, 14, 15, and 16.
An additional embodiment of the present invention relates to a peptide or polypeptide which has the amino acid sequence of an epitope-bearing portion of a Zneul polypeptide having an amino acid sequence described 20 above. Peptides or polypeptides having the amino acid sequence of an epitope-bearing portion of a Zneul polypeptide of the present invention include portions of such polypeptides with at least nine, preferably at least 15 and more preferably at least 3 0 to 50 amino acids, 25 although epitope-bearing polypeptides of any length up to and including the entire amino acid sequence of a polypeptide of the present invention described above are also included in the present invention. Specific examples of said polypeptides are defined by the amino acid 30 sequences of SEQ ID NOs:20-23. Also claimed are any of these polypeptides that are fused to another polypeptide or carrier molecule.
Another embodiment of the present invention 35 relates to a method for producing an antibody which binds to a peptide or polypeptide defined by SEQ ID NOs: 2-3,8,
Printed from Mimosa
4
9, 11-16, and 19-24 or to a peptide or polypeptide which is at least 90% identical to said peptide or polypeptide comprising inoculating an animal with said peptide or polypeptide or with a nucleic acid which encodes said 5 peptide or polypeptide, wherein said animal produces antibodies to said peptide or polypeptide; and isolating said antibody.
These and other aspects of the invention will become evident upon reference to the following detailed description.
DETAILED DESCRIPTION OF THE INVENTION
The teachings of all of the references cited herein are incorporated in their entirety by reference.
The term "allelic variant" is used herein to denote any of two or more alternative forms of a gene occupying the same chromosomal locus. Allelic variation arises naturally through mutation, and may result in 25 phenotypic polymorphism within populations Gene mutations can be silent (no change in the encoded polypeptide) or may encode polypeptides having altered amino acid sequence. The term allelic variant is also used herein to denote a protein encoded by an allelic 3 0 variant of a gene.
The term "expression vector" is used to denote a DNA molecule, linear or circular, that comprises a segment encoding a polypeptide of interest operably linked to 35 additional segments that provide for its transcription. Such additional segments include promoter and terminator
Printed from Mimosa
sequences, and may also include one or more origins of replication, one or more selectable markers, an enhancer, a polyadenylation signal, etc. Expression vectors are generally derived from plasmid or viral DNA, or may 5 contain elements of both.
The term "isolated", when applied to a polynucleotide, denotes that the polynucleotide has been removed from its natural genetic milieu and is thus free 10 of other extraneous or unwanted coding sequences, and is in a form suitable for use within genetically engineered protein production systems.
"Operably linked", when referring to DNA 15 segments, indicates that the segments are arranged so that they function in concert for their intended purposes, e.g. transcription initiates in the promoter and proceeds through the coding segment to the terminator.
A "polynucleotide" is a single- or double-
stranded polymer of deoxyribonucleotide or ribonucleotide bases read from the 5' to the 3' end. Polynucleotides include RNA and DNA, and may be isolated from natural sources, synthesized in vitro, or prepared from a 25 combination of natural and synthetic molecules.
The term "promoter" is used herein for its art-recognized meaning to denote a portion of a gene containing DNA sequences that provide for the binding of 30 RNA polymerase and initiation of transcription. Promoter sequences are commonly, but not always, found in the 5' non-coding regions of genes.
A "soluble protein" is a protein polypeptide that is not bound to a cell membrane.

Within preferred embodiments of the invention the isolated polynucleotides will hybridize to similar 5 sized regions of SEQ ID N0:1, or a sequence complementary thereto, under stringent conditions. In general,
stringent conditions are selected to be about 5°C lower than the thermal melting point (Tm) for the specific sequence at a defined ionic strength and pH. The Tm is 10 the temperature (under defined ionic strength and pH) at which 50% of the target sequence hybridizes to a perfectly matched probe. Typical stringent conditions are those in which the salt concentration is about 0.02 M or less at pH 7 and the temperature is at least about 6 0°C. As 15 previously noted, the isolated polynucleotides of the present invention include DNA and RNA. Methods for isolating DNA and RNA are well known m the art. Total RNA can be prepared using guanidine HCl extraction followed by isolation by centrifugation in a CsCl gradient, Chirgwin 20 et al. , Biochemistry 28:52-94 (1979). Poly (A)+ RNA is prepared from total RNA using the method of Aviv and Leder, Proc. Natl. Acad. Sci. USA 69:1408-1412 (1972). Complementary DNA (cDNA) is prepared from poly(A)+ RNA using known methods. Polynucleotides encoding Zneul 25 polypeptides are then identified and isolated by, for example, hybridization or PCR.
The polynucleotides of the present invention can be synthesized using DNA synthesizer. Currently the method 3 0 of choice is the phosphoramidite method. If chemically synthesized double stranded DNA is required for an application such as the synthesis of a gene or a gene fragment, then each complementary strand is made separately. The production of short genes (60 to 80 bp) is 35 technically straightforward and can be accomplished by synthesizing the complementary strands and then annealing

them. For the production of longer genes (>300 bp),
however, special strategies must be invoked, because the coupling efficiency of each cycle during chemical DNA synthesis is seldom 100%. To overcome this problem, 5 synthetic genes (double-stranded) are assembled in modular form from single-stranded fragments that are from 20 to 100 nucleotides in length. See Glick, Bernard R. and Jack J. Pasternak, Molecular Biotechnology, Principles & Applications of Recombinant DNA, (ASM Press, Washington, 10 D.C. 1994), Itakura, K. et al. Synthesis and use of synthetic oligonucleotides. Annu. Rev. Biochem. 53 : 323-356 (1984), and Climie, S. et al. Chemical synthesis of the thymidylate synthase gene. Proc. Natl. Acad. Sci. USA 87 :633-637 (1990).
Those skilled in the art will recognize that the sequences disclosed in SEQ ID NOS:l, 2 and 3 represent a single allele of the human. Allelic variants of these sequences can be cloned by probing cDNA or genomic 20 libraries from different individuals according to standard procedures.
The present invention further provides counterpart proteins and polynucleotides from other 25 species ("species orthologs"). Of particular interest are Zneul polypeptides from other mammalian species, including murine, porcine, ovine, bovine, canine, feline, equine, and other primates. Species orthologs of the human Zneul protein can be cloned using information and compositions 30 provided by the present invention in combination with conventional cloning techniques. For example, a cDNA can be cloned using mRNA obtained from a tissue or cell type that expresses the protein. Suitable sources of mRNA can be identified by probing Northern blots with probes 35 designed from the sequences disclosed herein. A library is then prepared from mRNA of a positive tissue or cell

8
line. A protein-encoding cDNA can then be isolated by a variety of methods, such as by probing with a complete or partial human or mouse cDNA or with one or more sets of degenerate probes based on the disclosed sequences. A 5 cDNA can also be cloned using the polymerase chain reaction, or PCR (Mullis, U.S. Patent No. 4,683,202),
using primers designed from the sequences disclosed herein. Within an additional method, the cDNA library can be used to transform or transfect host cells, and 10 expression of the cDNA of interest can be detected with an antibody to the protein. Similar techniques can also be applied to the isolation of genomic clones. As used and claimed the language "an isolated polynucleotide which encodes a polypeptide, said polynucleotide being defined 15 by SEQ ID NO: 2" includes all allelic variants and species orthologs of the polypeptide of SEQ ID NO:2.
The present invention also provides isolated protein polypeptides that are substantially homologous to 20 the polypeptide of SEQ ID NO: 3 and its species orthologs. By "isolated" is meant a protein or polypeptide that is found m a condition other than its native environment, such as apart from blood and animal tissue. In a preferred form, the isolated polypeptide is substantially 25 free of other polypeptides, particularly other polypeptides of animal origin. It is preferred to provide the polypeptides in a highly purified form, i.e. greater than 95% pure, more preferably greater than 99% pure. The term "substantially homologous" is used herein to denote 30 polypeptides having 50%, preferably 60%, more preferably at least 80%, sequence identity to the sequence shown in SEQ ID NO:2,or its species orthologs. Such polypeptides will more preferably be at least 90% identical, and most preferably 95% or more identical to SEQ ID NO:3,or its 35 species orthologs. Percent sequence identity is determined by conventional methods. See, for example,

Altschul et al., Bull. Math. Bio. 48: 603-616 (1986) and Henikoff and Henikoff, Proc. Natl. Acad. Sci. USA 89:10915-10919 (1992). Briefly, two amino acid sequences are aligned to optimize the alignment scores using a gap opening penalty of 10, a gap extension penalty of 1, and the "blossom 62" scoring matrix of Henikoff and Henikoff (ibid.) as shown in Table 1 (amino acids are indicated by the standard one-letter codes). The percent identity is then calculated as:
Total number of identical matches x 100
[length of the longer sequence plus the number of gaps introduced into the longer sequence in order to align the two sequences]

Sequence identity of polynucleotide molecules is determined by similar methods using a ratio as disclosed above.
polypeptides are characterized as having one or more amino acid substitutions, deletions or additions. These changes are preferably of a minor nature, that is conservative amino acid substitutions (see Table 2) and other 10 substitutions that do not significantly affect the folding or activity of the protein or polypeptide; small deletions, typically of one to about 3 0 amino acids; and small amino- or carboxyl-terminal extensions, such as an amino-terminal methionine residue, a small linker peptide 15 of up to about 20-25 residues, or a small extension that facilitates purification (an affinity tag), such as a poly-histidine tract, protein A, Nilsson et al., EMBO J. 4:1075, (1985); Nilsson et al. , Methods Enzymol. 198:2, (1991), glutathione S transferase, Smith and Johnson, Gene 20 57:31, (1988), or other antigenic epitope or binding domain. See, in general Ford et al. , Protein Expression and Purification 2: 95-107, (1991). DNAs encoding affinity tags are available from commercial suppliers (e.g., Pharmacia Biotech, Piscataway, NJ).

Essential amino acids in the polypeptides of the present invention can be identified according to procedures known in the art, such as site-directed 15 mutagenesis or alanine-scanning mutagenesis, Cunningham and Wells, Science 244, 1081-1085, (1989); Bass et al., Proc. Natl. Acad. Sci. USA 88:4498-4502, (1991). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant 20 molecules are tested for biological activity {e.g., ligand binding and signal transduction) to identify amino acid residues that are critical to the activity of the molecule. Sites of ligand-protein interaction can also be determined by analysis of crystal structure as determined 25 by such techniques as nuclear magnetic resonance,
crystallography or photoaffinity labeling. See, for example, de Vos et al., Science 255:306-312, (1992); Smith et al., J. Mol. Biol. 224:899-904, (1992); Wlodaver et al., FEBS Lett. 309:59-64, (1992). The identities of 3 0 essential amino acids can also be inferred from analysis of homologies with related proteins.
Multiple amino acid substitutions can be made and tested using known methods of mutagenesis and 35 screening, such as those disclosed by Reidhaar-Olson and Sauer, Science 241:53-51, (1988) or Bowie and Sauer, Proc.
Printed from Mimosa
WO 98/57983 PCT/US98/12763
13
Natl. Acad. Sci. USA 86:2152-2156, (1989). Briefly, these authors disclose methods for simultaneously randomizing two or more positions in a polypeptide, selecting for functional polypeptide, and then sequencing the 5 mutagenized polypeptides to determine the spectrum of allowable substitutions at each position. Other methods that can be used include phage display, e.g., Lowman et al., Biochem. 30:10832-10837, (1991); Ladner et al., U.S. Patent No. 5,223,409; Huse, WIPO Publication WO 92/06204, 10 and region-directed mutagenesis, Derbyshire et al., Gene 46:145, (1986); Ner et al., DNA 7:127, (1988)
Mutagenesis methods as disclosed above can be combined with high-throughput screening methods to detect 15 activity of cloned, mutagenized proteins in host cells.
Preferred assays in this regard include cell proliferation assays and biosensor-based ligand-binding assays, which are described below. Mutagenized DNA molecules that encode active proteins or portions thereof (e.g., ligand-binding
2 0 fragments) can be recovered from the host cells and rapidly sequenced using modern equipment. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide of interest, and can be applied to polypeptides of unknown 25 structure.
Using the methods discussed above, one of ordinary skill in the art can prepare a variety of polypeptides that are substantially homologous to SEQ ID
3 0 NO:3 or allelic variants thereof and retain the properties of the wild-type protein. As expressed and claimed herein the language, "a polypeptide as defined by SEQ ID NO: 2" includes all allelic variants and species orthologs of the polypeptide.

The protein polypeptides of the present invention, including full-length proteins, protein fragments (e.g. ligand-binding fragments), and fusion polypeptides can be produced in genetically engineered 5 host cells according to conventional techniques. Suitable host cells are those cell types that can be transformed or transfected with exogenous DNA and grown in culture, and include bacteria, fungal cells, and cultured higher eukaryotic cells. Eukaryotic cells, particularly cultured 10 cells of multicellular organisms, are preferred.
Techniques for manipulating cloned DNA molecules and introducing exogenous DNA into a variety of host cells are disclosed by Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd ed., Cold Spring Harbor Laboratory 15 Press, Cold Spring Harbor, NY, (1989), and Ausubel et al., ibid.
In general, a DNA sequence encoding a Zneul polypeptide is operably linked to other genetic elements 20 required for its expression, generally including a transcription promoter and terminator, within an expression vector. The vector will also commonly contain one or more selectable markers and one or more origins of replication, although those skilled in the art will 25 recognize that within certain systems selectable markers may be provided on separate vectors, and replication of the exogenous DNA may be provided by integration into the host cell genome. Selection of promoters, terminators, selectable markers, vectors and other elements is a matter 3 0 of routine design within the level of ordinary skill in the art. Many such elements are described in the literature and are available through commercial suppliers.
Another embodiment of the present invention 35 provides for a peptide or polypeptide comprising an epitope-bearing portion of a polypeptide of the invention.
Printed from Mimosa
The epitope of the this polypeptide portion is an immunogenic or antigenic epitope of a polypeptide of the invention. A region of a protein to which an antibody can bind is defined as an "antigenic epitope". See for 5 instance, Geysen, H.M. et al., Proc. Natl. Acad Sci. USA 81:3998-4002 (1984) .
As to the selection of peptides or polypeptides bearing an antigenic epitope (i.e., that contain a region 10 of a protein molecule to which an antibody can bind), it is well known in the art that relatively short synthetic peptides that mimic part of a protein sequence are routinely capable of eliciting an antiserum that reacts with the partially mimicked protein. See Sutcliffe, J.G. 15 et al. Science 219:660-666 (1983). Peptides capable of eliciting protein-reactive sera are frequently represented in the primary sequence of a protein, can be characterized by a set of simple chemical rules, and are confined neither to immunodominant regions of intact proteins 20 (i.e., immunogenic epitopes) nor to the amino or carboxyl terminals. Peptides that are extremely hydrophobic and those of six or fewer residues generally are ineffective at inducing antibodies that bind to the mimicked protein; longer soluble peptides, especially those containing 25 proline residues, usually are effective.
Antigenic epitope-bearing peptides and polypeptides of the invention are therefore useful to raise antibodies, including monoclonal antibodies, that 30 bind specifically to a polypeptide of the invention.
Antigenic epitope-bearing peptides and polypeptides of the present invention contain a sequence of at least nine, preferably between 15 to about 3 0 amino acids contained within the amino acid sequence of a polypeptide of the 35 invention. However, peptides or polypeptides comprising a larger portion of an amino acid sequence of the invention,
Printed from Mimosa
16
containing from 30 to 5 0 amino acids, or any length up to and including the entire amino acid sequence of a polypeptide of the invention, also are useful for inducing antibodies that react with the protein. Preferably, the 5 amino acid sequence of the epitope-bearing peptide is selected to provide substantial solubility in aqueous solvents (i.e., the sequence includes relatively hydrophilic residues and hydrophobic residues are preferably avoided); and sequences containing proline 10 residues are particularly preferred. All of the polypeptides shown in the sequence listing contain antigenic epitopes to be used according to the present invention, however, specifically designed antigenic epitopes include the peptides defined by SEQ ID NOs:20-24.
the present invention encode the above-described polypeptides. A cDNA sequence which encodes a polypeptide of the present invention is comprised of a series of 20 codons, each amino acid residue of the polypeptide being encoded by a codon and each codon being comprised of three nucleotides. The ammo acid residues are encoded by their respective codons as follows.
Alanine (Ala) is encoded by GCA, GCC, GCG or
Polynucleotides, generally a cDNA sequence, of
GCT ;
Cysteine (Cys) is encoded by TGC or TGT;
Aspartic acid (Asp) is encoded by GAC or GAT Glutamic acid (Glu) is encoded by GAA or GAG Phenylalanine (Phe) is encoded by TTC or TTT Glycine (Gly) is encoded by GGA, GGC, GGG or
GGT;
Histidine (His) is encoded by CAC or CAT; Isoleucine (lie) is encoded by ATA, ATC or ATT; Lysine (Lys) is encoded by AAA, or AAG;
Printed from Mimosa
Leucine (Leu) is encoded by TTA, TTG, CTA, CTC, CTG or CTT;
Methionine (Met) is encoded by ATG;
Asparagine (Asn) is encoded by AAC or AAT;
Proline (Pro) is encoded by CCA, CCC, CCG or
CCT;
Glutamine (Gin) is encoded by CAA or CAG;
Arginine (Arg) is encoded by AGA, AGG, CGA, CGC, CGG or CGT;
Serine (Ser) is encoded by AGC, AGT, TCA, TCC,
TCG or TCT;
Threonine (Thr) is encoded by ACA, ACC, ACG or
ACT;
Valine (Val) is encoded by GTA, GTC, GTG or GTT; 15 Tryptophan (Trp) is encoded by TGG; and
Tyrosine (Tyr) is encoded by TAC or TAT.
It is to be recognized that according to the present invention, when a cDNA is claimed as described 20 above, it is understood that what is claimed are both the sense strand, the anti-sense strand, and the DNA as double-stranded having both the sense and anti-sense strand annealed together by their respective hydrogen bonds. Also claimed is the messenger RNA (mRNA) which 25 encodes the polypeptides of the present invention, and which mRNA is encoded by the above-described cDNA. A messenger RNA (mRNA) will encode a polypeptide using the same codons as those defined above, with the exception that each thymine(T) is replaced by a uracil nucleotide 30 (U).
To direct a Zneul polypeptide into the secretory pathway of a host cell, a secretory signal sequence (also known as a leader sequence, prepro sequence or pre 3 5 sequence) is provided in the expression vector. The secretory signal sequence may be that of the protein, or
Printed from Mimosa
18
may be derived from another secreted protein (e.g., t-PA) or synthesized de novo. The secretory signal sequence is joined to the Zneul DNA sequence in the correct reading frame. Secretory signal sequences are commonly positioned 5 51 to the DNA sequence encoding the polypeptide of interest, although certain signal sequences may be positioned elsewhere in the DNA sequence of interest (see, e.g., Welch et al., U.S. Patent No. 5,037,743; Holland et al., U.S. Patent No. 5,143,830).
Cultured mammalian cells are preferred hosts within the present invention. Methods for introducing exogenous DNA into mammalian host cells include calcium phosphate-mediated transfection, Wigler et al., Cell 15 14:725, (1978); Corsaro and Pearson, Somatic Cell Genetics 7:603, (1981): Graham and Van der Eb, Virology 52:456, (1973), electroporation, Neumann et al., EMBO J. 2:841-845, (1982), DEAE-dextran mediated transfection, Ausubel et al., eds., Current Protocols in Molecular Biology, John 20 Wiley and Sons, Inc., NY, (1987), and liposome-mediated transfection, Hawley-Nelson et al., Focus 15:73, (1993); Ciccarone et al., Focus 25:80, (1993). The production of recombinant polypeptides in cultured mammalian cells is disclosed, for example, by Levinson et al., U.S. Patent 25 No. 4,713,339; Hagen et al., U.S. Patent No. 4,784,950; Palmiter et al., U.S. Patent No. 4,579,821; and Ringold, U.S. Patent No. 4,656,134. Suitable cultured mammalian cells include the COS-1 (ATCC No. CRL 1650), COS-7 (ATCC No. CRL 1651), BHK (ATCC No. CRL 1632), BHK 570 (ATCC No. 30 CRL 10314), 293, ATCC No. CRL 1573; Graham et al., J. Gen. Virol. 36:59-72, (1977) and Chinese hamster ovary (e.g. CHO-K1; ATCC No. CCL 61) cell lines. Additional suitable cell lines are known in the art and available from public depositories such as the American Type Culture Collection, 35 Rockville, Maryland. In general, strong transcription promoters are preferred, such as promoters from SV-4 0 or

Drug selection is generally used to select for cultured mammalian cells into which foreign DNA has been inserted. Such cells are commonly referred to as "transfectants". Cells that have been cultured in the 10 presence of the selective agent and are able to pass the gene of interest to their progeny are referred to as "stable transfectants." A preferred selectable marker is a gene encoding resistance to the antibiotic neomycin. Selection is carried out in the presence of a neomycin-15 type drug, such as G-418 or the like. Selection systems may also be used to increase the expression level of the gene of interest, a process referred to as "amplification." Amplification is carried out by culturing transfectants in the presence of a low level of
2 0 the selective agent and then increasing the amount of selective agent to select for cells that produce high levels of the products of the introduced genes. A preferred amplifiable selectable marker is dihydrofolate reductase, which confers resistance to methotrexate. 25 Other drug resistance genes (e.g. hygromycin resistance, multi-drug resistance, puromycin acetyltransferase) can also be used.
Other higher eukaryotic cells can also be used

Transformed or transfected host cells are cultured according to conventional procedures in a culture medium containing nutrients and other components required for the growth of the chosen host cells. A variety of suitable media, including defined media and complex media, 10 are known in the art and generally include a carbon source, a nitrogen source, essential amino acids, vitamins and minerals. Media may also contain such components as growth factors or serum, as required. The growth medium will generally select for cells containing the exogenously 15 added DNA by, for example, drug selection or deficiency in an essential nutrient which is complemented by the selectable marker carried on the expression vector or co-transfected into the host cell.
Within one aspect of the present invention, a novel protein is produced by a cultured cell, and the cell is used to screen for a receptor or receptors for the protein, including the natural receptor, as well as agonists and antagonists of the natural ligand.
PROTEIN ISOLATION:
Expressed recombinant polypeptides (or chimeric polypeptides) can be purified using fractionation and/or 3 0 conventional purification methods and media. Ammonium sulfate precipitation and acid or chaotrope extraction may be used for fractionation of samples. Exemplary purification steps may include hydroxyapatite, size exclusion, FPLC and reverse-phase high performance liquid 35 chromatography. Suitable anion exchange media include derivatized dextrans, agarose, cellulose, polyacrylamide,
Printed from Mimosa
22
specialty silicas, and the like. PEI, DEAE, QAE and Q derivatives are preferred, with DEAE Fast-Flow Sepharose (Pharmacia, Piscataway, NJ) being particularly preferred. Exemplary chromatographic media include those media 5 derivatized with phenyl, butyl, or octyl groups, such as Phenyl-Sepharose FF (Pharmacia), Toyopearl butyl 650 (Toso Haas, Montgomeryville, PA), Octyl-Sepharose (Pharmacia) and the like; or polyacrylic resins, such as Amberchrom CG 71 (Toso Haas) and the like. Suitable solid supports 10 include glass beads, silica-based resins, cellulosic resins, agarose beads, cross-linked agarose beads, polystyrene beads, cross-linked polyacrylamide resins and the like that are insoluble under the conditions in which they are to be used. These supports may be modified with 15 reactive groups that allow attachment of proteins by amino groups, carboxyl groups, sulfhydryl groups, hydroxyl groups and/or carbohydrate moieties. Examples of coupling chemistries include cyanogen bromide activation, N-hydroxysuccinimide activation, epoxide activation, 20 sulfhydryl activation, hydrazide activation, and carboxyl and amino derivatives for carbodiimide coupling chemistries. These and other solid media are well known and widely used in the art, and are available from commercial suppliers. Methods for binding receptor 25 polypeptides to support media are well known in the art. Selection of a particular method is a matter of routine design and is determined in part by the properties of the chosen support. See, for example, Affinity Chromatography: Principles & Methods, Pharmacia LKB 30 Biotechnology, Uppsala, Sweden, (1988).
The polypeptides of the present invention can be isolated by exploitation of their properties. For example, immobilized metal ion adsorption (IMAC) 35 chromatography can be used to purify histidine-rich proteins. Briefly, a gel is first charged with divalent
Printed from Mimosa
23
metal ions to form a chelate, E. Sulkowski, Trends in Biochem. 3:1-7, (1985). Histidine-rich proteins will be adsorbed to this matrix with differing affinities, depending upon the metal ion used, and will be eluted by 5 competitive elution, lowering the pH, or use of strong chelating agents. Other methods of purification include purification of glycosylated proteins by lectin affinity chromatography and ion exchange chromatography, Methods in Enzymol., Vol. 182, "Guide to Protein Purification", M. 10 Deutscher, (ed.), Acad. Press, San Diego, (1990), pp.529-39. Alternatively, a fusion of the polypeptide of interest and an affinity tag (e.g., polyhistidine,
maltose-binding protein, an immunoglobulin domain) may be constructed to facilitate purification.
Physical Structure of Zneul
The Zneul polypeptide shown in SEQ ID NO: 2 has a signal peptide including amino acid residues 1-19. Amino 20 acid residues 20-104 define a hydrophilic domain homologous to an HSMHC3W5A domain, SEQ ID NO: 17, (GenBank No. gl401159) . Ammo acid residues 105-135 define a domain homologous to an Epidermal Growth Factor (EGF) domain. Amino acid residues 13 6-177 define another domain 25 homologous to an EGF domain; and amino acid residues 178-273 define a domain also homologous to an HSMHC3W5A domain.
However, the first EGF-like domain (EGF1) of 30 Zneul, SEQ ID NO: 9 which corresponds to amino acid residues 105 to 135 of SEQ ID NO: 2, is distinct from any other EGF domain m the prior art. The EGF1 in Zneul is about 56% similar to the HSMHC3W5A_6 domain, its closest human relative.
Printed from Mimosa
24
The second EGF-like domain (EGF2) of Zneul, SEQ ID NO: 10 which corresponds to amino acid residues 136 to 177 of SEQ ID NO: 2,is distinct from any other EGF domain in the prior art. EGF2 of Zneul is about 48% similar to 5 PIR_S31101 fibrillin, its closest human relative.
The first HSMHC3W5A-like (HSM1) domain of Zneul, SEQ ID NO: 8 which corresponds to amino acid residues 20-104 of SEQ ID NO: 2. SEQ ID NO: 8 is approximately 38% 10 similar to HSMHC3W5A,its closest human relative.
The second HSMHC3W5A-like domain (HSM2) of Zneul, SEQ ID NO: 11 which corresponds to amino acid residues 178-273 of SEQ ID NO: 2, is distinct from any 15 other polypeptide in the prior art. It is about 32%
similar to HSMHC3W5A_6.
Uses
The tissue specificity of Zneul expression indicates that Zneul can be used as a growth, maintenance, or differentiation factor in the spinal cord, heart, spleen, testis, thyroid and lymph nodes.
The present invention also provides reagents which will find use in diagnostic applications. For example, the Zneul gene has been mapped on chromosome 9q34.3. A Zneul nucleic acid probe could be used to check for abnormalities in chromosome 9. In a normal chromosome 3 0 9, one would predict that a Zneul nucleic acid probe would hybridize to chromosome 9. If the probe does not hybridize to chromosome 9, this would indicate an abnormality in chromosome 9.
Zneul's closest human homolog is HSMHC3W5A a gene in the HLA class III region, which is contained in a
Printed from Mimosa
cosmid which contains Notch 4. Zneul is also homologous to Notch 4 in its EGF-like domains. Zneul may be involved in EGF-receptor pathways.
Notch Structure/Function
The original member of this gene family was the Drosophila gene Notch which controls cell fate decisions in the development of the peripheral nervous system. 10 Notch is a cell surface receptor with a single transmembrane domain. Homologues have now been found in C. elegans (linl2 and glpl), Xenopus, mouse and human. All members of the Notch family have large numbers of EGF-like motifs (29-39 in mouse, 10-13 in C. elegans) and three or 15 more copies of LNR (linl2/ Notch repeats) in the extracellular domain. Notch family members also contain six copies of the cdclO/SWI6 motif (also called ankyrin repeats) and a PEST protein degradation sequence in the intracellular domain. Specific EGF repeats (Drosophila 20 repeats 11 and 12) are involved in ligand binding. LNR may be regulatory domains which bind ligand when high ligand concentrations exist and cause decreased activity of Notch. CdclO/SWI6 domains are involved in protein-protein interactions with components of the Notch-25 activated signal transduction pathway.
Notch Biology
Two different translocations led to formation of 3 0 altered Notch genes resulting in an oncogenic state. The TAN-1 oncogene is a fusion of part of the fi T cell receptor with a small region of the human Notch 1 extracellular domain and the entire intracellular domain. TAN-1 is an activated form of Notch which causes T-35 lymphoblastic leukemias. The int-3 oncogene is caused by" integration of the mouse mammary tumor virus into the
Printed from Mimosa
26
Notch 4 gene resulting in expression of the intact intracellular domain. Int-3 also is an activated form of Notch which leads to mammary carcinoma.
The function of Notch family members has been extensively studied in Drosophila and C. elegans. These proteins control binary decisions that depend on cell-cell interactions. Notch proteins act consistent with their proposed role as a receptor. Gain-of-function and loss-10 of-function Notch alleles result in opposite cell fate decisions. Notch receptors and their ligands play important roles in lateral inhibition, the process whereby signaling between neighboring cells is amplified by a feedback loop between Notch and its ligand. This process 15 results in increased receptor activity in some cells and increased ligand activity in others leading to the distinction between signaling cells and receiving cells.
It has recently been shown that the expression 20 of an activated form of Notchl in developing T cells of the mouse leads to both an increase in CD8 lineage T cells and a decrease in CD4 lineage T cells. Expression of activated Notch permits the development of mature CD8 lineage thymocytes even in the absence of class I major 25 histocompatability complex (MHC) proteins, ligands that are normally required for the development of these cells. However, activated Notch is not sufficient to promote CD8 when both class I and class II MHC are absent. These results implicate Notch as a participant in the CD4 versus 30 CD8 lineage decision. Robey, E. et al. Cell 87: 483-492 (1996) .
Mutations in a gene region called CADASIL (for cerebral autosomal dominant arteriopathy with subcortical 35 infarcts and leukoencephalopathy) on chromosome 19 are associated with a type of stroke and dementia whose key
Printed from Mimosa
27
features include recurrent subcortical ischaemic events and vascular dementia. Notch3 has been mapped to this region, and mutations in CADASIL patients indicate that Notch3 could be the defective protein in CADASIL patients, 5 Joutel, A. et al. Nature 383:707-710 (1996).
Notch Ligands
There is also a conserved family of ligands for 10 the Notch receptor family. Multiple ligands are able to activate the same receptor. For example, delta and serrate each act as ligands for Drosophila Notch. These ligands all contain EGF repeats (from 1-14), a DSL domain (delta, serrate, lag-2) and a transmembrane domain. 15 Therefore, receptor and ligand are homologous to one another. In addition, receptor and ligand are often coexpressed and are associated with each other in vesicles.
Zneul Structure
Zneul is similar to Notch and its ligands in having two EGF repeats. However, it has a small number of EGF repeats and lacks a membrane spanning domain, 25 linl2/Notch domains and ankyrin repeats. Based on structure/function experiments of Notch, one would predict that Zneul would antagonize Notch function. If the EGF repeats m zneul could bind receptor, it could inhibit ligand binding on neighboring cells. Furthermore, Zneul 3 0 may have its own target receptor for which it would be an agonist.
Zneul Tissue Distribution/Multiple mRNA sizes
Zneul is widely expressed in adult human tissues. Zneul is most highly expressed in heart,
Printed from Mimosa
28
placenta, spleen, testis, thyroid, spinal cord and lymph node. Dot blots indicate that Zneul is also expressed in a variety of fetal tissues. There are at least three mRNA sizes:
1.3 kb mRNA only in brain and testis 1.7 kb only in lymph node
1.3 + 1.7 in multiple tissues
2.4 kb only in placenta
Since the sequence of Zneul is from the 1.3 kb mRNA in brain, it is difficult to predict what types of molecules the larger transcripts encode. It is possible that larger forms could encode soluble Zneul proteins with 15 more EGF repeats and other domains observed in Notch or Notch ligands. Alternatively, the extra sequences could encode transmembrane and intracellular domains.
Possible relationship to Notch function
It is difficult to predict whether Zneul will act as a Notch ligand or to antagonize the activity of other Notch ligands by competing for receptor binding. Zneul may alter the binary decisions m differentiation of 25 stem cells into specific lineages or may alter the cell fate decisions of adjacent cells.
Alternatively, Zneul may have nothing to do with Notch. Many proteins have EGF repeats. Zneul may act as 30 a growth factor for a different class of receptor.
Other Possible Roles
• role in breast cancer (EGF-receptor is 35 overexpressed in many breast cancers)
Printed from Mimosa
29
• role in glioblastomas, pituitary adenomas.
Mapping Data
Zneul maps to human chromosome 9q34.3, in the same chromosomal band as Notchl. It is of interest that Notch4 and HSMHC3W5A are also linked at the MHC III locus, i.e., duplication of an authentic Notch receptor and a 2 10 EGF-repeat novel protein.
Therapeutic utility
Zneul and its antagonists can be used as therapeutic reagents for the following.
1. Alzheimer's disease
The Sell2 gene was identified as a suppresser of a linl2 gain-of-function mutant. Sell2 is a homolog of a positional cloned human early-onset familial Alzheimer's disease gene. Therefore, Zneul could affect a pathway affecting this disease and it is expressed m brain, 25 albeit at lower levels than most other tissues.
2. Cancer
There are a number of chromosomal rearrangements 3 0 associated with breakpoints at 9q34 including Non-
Hodgkin's lymphoma and acute myeloid leukemia. A probe for Zneul which does not properly hybridize to chromosome 9q34 would indicate an abnormality of chromosome 9 and would indicate a possible predilection of the individual for 35 developing cancer.
Printed from Mimosa
Given the possible association with Notch 4, an endothelial-specific gene, Zneul could be involved in promoting or inhibiting endothelial cell tumors such as hemangiopericytomas? Another possibility is in 5 angiogenesis since blocking a tumor's blood supply would be an effective cancer treatment.
Given the tissues where Zneul is highly expressed, the most prevalent forms of cancer would be in 10 the testis and lymph nodes.
3. Hematopoiesis
Moore et al (PNAS 94:4011-4016, 1997) implicated 15 delta-like (a mammalian Notch ligand) in promoting both high-proliferative potential progenitors and in stem cell repopulation. Since Zneul is highly expressed in lymph node and spleen, it could either be involved in inhibiting differentiation to promote stem cell self-renewal or in 20 determination of progenitor populations. Possible use in repopulating blood cells after chemotherapy treatment or in vitro expansion of stem cells.
4. Heart
Stimulation of myofibroblast proliferation or migration in the repair process after myocardial infarction. Recently, a frizzled homolog has been implicated in this process. There is evidence for 30 interactions between the frizzled and Notch pathways in Drosophila.
. Placenta
Stimulation or inhibition of various growth factor made in placenta.
Printed from Mimosa
31
6. Testis
Role in fertility or contraception
7. Spinal cord
Zneul may play a role in Nerve regeneration since Notch plays a role in neurogenesis in both flies and 10 mammalian cells.
The present invention also provides reagents with significant therapeutic value. The Zneul polypeptide 15 (naturally occurring or recombinant), fragments thereof, antibodies and anti-idiotypic antibodies thereto, along with compounds identified as having binding affinity to the Zneul polypeptide, should be useful in the treatment of conditions associated with abnormal physiology or 20 development, including abnormal proliferation, e.g., cancerous conditions, or degenerative conditions. For example, a disease or disorder associated with abnormal expression or abnormal signaling by a Zneul polypeptide should be a likely target for an agonist or antagonist of 25 the Zneul polypeptide.
Antibodies to the Zneul polypeptide can be purified and then administered to a patient. These reagents can be combined for therapeutic use with 30 additional active or inert ingredients, e.g., in pharmaceutically acceptable carriers or diluents along with physiologically innocuous stabilizers and excipients. These combinations can be sterile filtered and placed into dosage forms as by lyophilization in dosage vials or 35 storage in stabilized aqueous preparations. This invention also contemplates use of antibodies, binding fragments
Printed from Mimosa
32
thereof or single-chain antibodies of the antibodies including forms which are not complement binding.
The quantities of reagents necessary for 5 effective therapy will depend upon many different factors, including means of administration, target site, physiological state of the patient, and other medications administered. Thus, treatment dosages should be titrated to optimize safety and efficacy. Typically, dosages used 10 in vitro may provide useful guidance in the amounts useful for in vivo administration of these reagents. Animal testing of effective doses for treatment of particular disorders will provide further predictive indication of human dosage. Methods for administration include oral, 15 intravenous, peritoneal, intramuscular, or transdermal administration. Pharmaceutically acceptable carriers will include water, saline, buffers to name just a few. Dosage ranges would ordinarily be expected from l^g to lOOOng per kilogram of body weight per day. However, the doses by be 20 higher or lower as can be determined by a medical doctor with ordinary skill in the art. For a complete discussion of drug formulations and dosage ranges see Remington's Pharmaceutical Sciences,17th Ed., (Mack Publishing Co., Easton, Penn., 1990), and Goodman and Gilman's: The 25 Pharmacological Bases of Therapeutics,9th Ed. (Pergamon Press 1996).
Nucleic Acid-based Therapeutic Treatment
If a mammal has a mutated or lacks a Zneul gene,
the Zneul gene can be introduced into the cells of the mammal. In one embodiment, a gene encoding a Zneul polypeptide is introduced in vivo in a viral vector. Such vectors include an attenuated or defective DNA virus, such 35 as but not limited to herpes simplex virus (HSV),
papillomavirus, Epstein Barr virus (EBV), adenovirus,
Printed from Mimosa
33
adeno-associated virus (AAV), and the like. Defective viruses , which entirely or almost entirely lack viral genes, are preferred. A defective virus is not infective after introduction into a cell. Use of defective viral 5 vectors allows for administration to cells in a specific, localized area, without concern that the vector can infect other cells. Examples of particular vectors include, but are not limited to, a defective herpes virus 1 (HSV1) vector [Kaplitt et al., Molec. Cell. Neurosci.,2 :320-330 10 (1991)], an attenuated adenovirus vector, such as the vector described by Stratford-Perricaudet et al., J. Clin. Invest., 90 :626-630 (1992), and a defective adeno-associated virus vector [Samulski et al., J. Virol., 61:3096-3101 (1987); Samulski et al. J. Virol., 63:3822-15 3828 (1989)] .
In another embodiment, the gene can be introduced in a retroviral vector, e.g., as described in Anderson et al., U.S. Patent No. 5,399,346; Mann et al., 20 Cell, 33:153 (1983); Temin et al., U.S. Patent No. 4,650,764; Temin et al., U.S. Patent No. 4,980,289; Markowitz et al., J. Virol., 62:1120 (1988); Temin et al., U.S. Patent No. 5,124,263; International Patent Publication No. WO 95/07358, published March 16, 1995 by 25 Dougherty et al.; and Blood, 82:845 (1993).
Alternatively, the vector can be introduced by lipofection in vivo using liposomes. Synthetic cationic lipids can be used to prepare liposomes for m vivo 30 transfection of a gene encoding a marker [Feigner et al., Proc. Natl. Acad. Sci. USA, 84:7413-7417 (1987); see Mackey et al., Proc. Natl. Acad. Sci. USA, 85:8027-8031 (1988)]. The use of lipofection to introduce exogenous genes into specific organs in vivo has certain practical 35 advantages. Molecular targeting of liposomes to specific cells represents one area of benefit. It is clear that
Printed from Mimosa
34
directing transfection to particular cells represents one area of benefit. It is clear that directing transfection to particular cell types would be particularly advantageous in a tissue with cellular heterogeneity, such 5 as the pancreas, liver, kidney, and brain. Lipids may be chemically coupled to other molecules for the purpose of targeting. Targeted peptides, e.g., hormones or neurotransmitters, and proteins such as antibodies, or non-peptide molecules could be coupled to liposomes 10 chemically.
It is possible to remove the cells from the body and introduce the vector as a naked DNA plasmid and then re-implant the transformed cells into the body. Naked DNA 15 vector for gene therapy can be introduced into the desired host cells by methods known in the art, e.g.,
transfection, electroporation, microinjection,
transduction, cell fusion, DEAE dextran, calcium phosphate precipitation, use of a gene gun or use of a DNA vector 20 transporter [see, e.g., Wu et al., J. Biol. Chem.,
267:963-967 (1992); Wu et al., J. Biol. Chem., 263:14621-14624 (1988)] .
ANTIBODIES
ZNEU1 polypeptides can also be used to prepare antibodies that specifically bind to Zneul epitopes, peptides or polypeptides. The Zneul polypeptide or a fragment thereof serves as an antigen (immunogen) to 30 inoculate an animal and elicit an immune response.
Suitable antigens would be the Zneul polypeptide encoded by SEQ ID NO:2 or 3 or at least a contiguous 9 amino acid fragment thereof. Antibodies generated from this immune response can be isolated and purified as described herein. 35 Methods for preparing and isolating polyclonal and monoclonal antibodies are well known m the art. See, for
Printed from Mimosa
example, Current Protocols in Immunology, Cooligan, et al. (eds.), National Institutes of Health, (John Wiley and Sons, Inc., 1995); Sambrook et al., Molecular Cloning: A Laboratory Manual, Second Edition (Cold Spring Harbor, NY, 5 1989); and Hurrell, J. G. R., Ed., Monoclonal Hybridoma Antibodies: Techniques and Applications (CRC Press, Inc., Boca Raton, FL, 1982).
As would be evident to one of ordinary skill in 10 the art, polyclonal antibodies can be generated from inoculating a variety of warm-blooded animals such as horses, cows, goats, sheep, dogs, chickens, rabbits, mice, and rats with a Zneul polypeptide or a fragment thereof. The immunogenicity of a Zneul polypeptide may be increased 15 through the use of an adjuvant, such as alum (aluminum hydroxide) or Freund's complete or incomplete adjuvant. Polypeptides useful for immunization also include fusion polypeptides, such as fusions of Zneul or a portion thereof with an immunoglobulin polypeptide or with maltose 20 binding protein. The polypeptide immunogen may be a full-length molecule or a portion thereof. If the polypeptide portion is "hapten-like", such portion may be advantageously joined or linked to a macromolecular carrier (such as keyhole limpet hemocyanm (KLH), bovine 25 serum albumin (BSA) or tetanus toxoid) for immunization.
As used herein, the term "antibodies" includes polyclonal antibodies, affinity-purified polyclonal antibodies, monoclonal antibodies, and antigen-binding 30 fragments, such as F(ab')2 anc* Fab proteolytic fragments. Genetically engineered intact antibodies or fragments,
such as chimeric antibodies, Fv fragments, single chain antibodies and the like, as well as synthetic antigen-binding peptides and polypeptides, are also included.
Printed from Mimosa
Non-human antibodies may be humanized by grafting non-human CDRs onto human framework and constant regions, or by incorporating the entire non-human variable domains (optionally "cloaking" them with a human-like surface by 5 replacement of exposed residues, wherein the result is a "veneered" antibody). In some instances, humanized antibodies may retain non-human residues within the human variable region framework domains to enhance proper binding characteristics. Through humanizing antibodies, 10 biological half-life may be increased, and the potential for adverse immune reactions upon administration to humans is reduced.
Alternative techniques for generating or 15 selecting antibodies useful herein include m vitro exposure of lymphocytes to Zneul protein or peptide, and selection of antibody display libraries in phage or similar vectors (for instance, through use of immobilized or labeled Zneul protein or peptide). Genes encoding 20 polypeptides having potential Zneul polypeptide binding domains can be obtained by screening random peptide libraries displayed on phage (phage display) or on bacteria, such as E. coli. Nucleotide sequences encoding the polypeptides can be obtained in a number of ways, such 25 as through random mutagenesis and random polynucleotide synthesis. These random peptide display libraries can be used to screen for peptides which interact with a known target which can be a protein or polypeptide, such as a ligand or receptor, a biological or synthetic 30 macromolecule, or organic or inorganic substances.
Techniques for creating and screening such random peptide display libraries are known in the art (Ladner et al., US Patent NO. 5,223,409; Ladner et al., US Patent NO. 4,946,778; Ladner et al., US Patent NO. 5,403,484 and
Printed from Mimosa
37
Ladner et al., US Patent NO. 5,571,698) and random peptide display libraries and kits for screening such libraries are available commercially, for instance from Clontech (Palo Alto, CA), Invitrogen Inc. (San Diego, CA) , New 5 England Biolabs, Inc. (Beverly, MA) and Pharmacia LKB Biotechnology Inc. (Piscataway, NJ). Random peptide display libraries can be screened using the Zneul sequences disclosed herein to identify proteins which bind to Zneul. These "binding proteins" which interact with 10 Zneul polypeptides can be used for tagging cells; for isolating homolog polypeptides by affinity purification; they can be directly or indirectly conjugated to drugs, toxins, radionuclides and the like. These binding proteins can also be used in analytical methods such as 15 for screening expression libraries and neutralizing activity. The binding proteins can also be used for diagnostic assays for determining circulating levels of polypeptides; for detecting or quantitating soluble polypeptides as marker of underlying pathology or disease. 20 These binding proteins can also act as Zneul "antagonists" to block Zneul binding and signal transduction m vitro and in vivo. These anti-Zneul binding proteins would be useful for down regulating the effect of Zneul.
Antibodies are determined to be specifically binding if: 1) they exhibit a threshold level of binding activity, and/or 2) they do not significantly cross-react with related polypeptide molecules. First, antibodies herein specifically bind if they bind to a Zneul 30 polypeptide, peptide or epitope with a binding affinity
6 —1 7 —I
(Ka) of 10 M or greater, preferably 10 M or greater,
8 —1
more preferably 10 M or greater, and most preferably 9 -1
M or greater. The binding affinity of an antibody -
Printed from Mimosa
38
can be readily determined by one of ordinary skill in the art, for example, by Scatchard analysis.
Second, antibodies are determined to 5 specifically bind if they do not significantly cross-react with related polypeptides. Antibodies do not significantly cross-react with related polypeptide molecules, for example, if they detect Zneul but not known related polypeptides using a standard Western blot analysis 10 (Ausubel et al., ibid.). Examples of known related polypeptides are orthologs, proteins from the same species that are members of a protein family (e.g. IL-16), Zneul polypeptides, and non-human Zneul. Moreover, antibodies may be "screened against" known related polypeptides to 15 isolate a population that specifically binds to the inventive polypeptides. For example, antibodies raised to Zneul are adsorbed to related polypeptides adhered to insoluble matrix; antibodies specific to Zneul will flow through the matrix under the proper buffer conditions. 20 Such screening allows isolation of polyclonal and monoclonal antibodies non-crossreactive to closely related polypeptides, Antibodies: A Laboratory Manual, Harlow and Lane (eds.) (Cold Spring Harbor Laboratory Press, 1988); Current Protocols in Immunology, Cooligan, et al. (eds.), 25 National Institutes of Health (John Wiley and Sons, Inc., 1995). Screening and isolation of specific antibodies is well known in the art. See, Fundamental Immunology, Paul (eds.) (Raven Press, 1993); Getzoff et al., Adv. in Immunol. 43: 1-98 (1988); Monoclonal Antibodies: 30 Principles and Practice, Goding, J.W. (eds.), (Academic Press Ltd., 1996); Benjamin et al., Ann. Rev.

A variety of assays known to those skilled in the art can be utilized to detect antibodies which specifically bind to Zneul proteins or peptides.
Exemplary assays are described in detail in Antibodies: A 5 Laboratory Manual, Harlow and Lane (Eds.) (Cold Spring Harbor Laboratory Press, 1988). Representative examples of such assays include: concurrent Immunoelectrophoresis, radioimmunoassay, radioimmuno-precipitation, enzyme-linked immunosorbent assay (ELISA), dot blot or Western blot 10 assay, inhibition or competition assay, and sandwich assay. In addition, antibodies can be screened for binding to wild-type versus mutant Zneul protein or polypeptide.
Antibodies to Zneul may be used for tagging cells that express Zneul; for isolating Zneul by affinity purification; for diagnostic assays for determining circulating levels of Zneul polypeptides; for detecting or quantitating soluble Zneul as marker of underlying 20 pathology or disease; in analytical methods employing
FACS; for screening expression libraries; for generating anti-idiotypic antibodies; and as neutralizing antibodies or as antagonists to block Zneul m vitro and in vivo. Suitable direct tags or labels include radionuclides, 25 enzymes, substrates, cofactors, inhibitors, fluorescent markers, chemiluminescent markers, magnetic particles and the like; indirect tags or labels may feature use of biotin-avidin or other complement/anti-complement pairs as intermediates. Antibodies herein may also be directly or 30 indirectly conjugated to drugs, toxins, radionuclides and the like, and these conjugates used for in vivo diagnostic or therapeutic applications. Moreover, antibodies to Zneul or fragments thereof may be used m vitro to detect denatured Zneul or fragments thereof in assays, for 35 example, Western Blots or other assays known in the art.

An additional embodiment of the present invention relates to a peptide or polypeptide which has the amino acid sequence of an epitope-bearing portion of a Zneul polypeptide having an amino acid sequence described 5 above. Peptides or polypeptides having the amino acid sequence of an epitope-bearing portion of a Zneul polypeptide of the present invention include portions of such polypeptides with at least nine, preferably at least 15 and more preferably at least 3 0 to 5 0 amino acids, 10 although epitope-bearing polypeptides of any length up to and including the entire amino acid sequence of a polypeptide of the present invention described above are also included in the present invention. Examples of said polypeptides are defined by the amino acid sequences of 15 SEQ ID NOs:20-23. Also claimed are any of these polypeptides that are fused to another polypeptide or carrier molecule.
The invention is further illustrated by the following non-limiting examples.
Example 1. Cloning of Zneul
Zneul was identified from expressed sequence tag (EST) SEQ ID NO: 4. The cDNA clone containing the EST was discovered in a brain cDNA library which contained the EST. The cDNA was isolated from E. coh transfected with 30 the plasmid and then streaked out on an LB 100 ng/ml ampicillin and 100 jig/ml methicillm plate. The cDNA insert was sequenced. The insert was determined to be 1514 base pairs long with a 27 4 amino acid open reading frame and a putative 19 amino acid signal peptide.

Example 2 Northern Blot Analysis
Human multiple tissue blots 1,2,3 (Clontech)were probed to determine the tissue distribution of Zneul. A 5 Hindlll/NotI fragment containing the entire Zneul coding region was generated from the isolated cDNA clone and used for the probe. A plasmid prep of the clone was prepared from a 5 ml LB 100 (ag/ml ampicillin overnight culture at 37° using the QIAprep Spin Miniprep Kit (Qiagen) . 20 |il out 10 of 100 (il were digested with 3 p.1 of NEB Buffer 3, 10 units of Hindlll (Gibco BRL) and 10 units Notl (New England Biolabs) in a 30 fil reaction at 37°C for 2 hours. The digest was electrophoresed on a 0.8% TBE agarose gel and the fragment was cut out. The DNA was extracted from 15 the gel slab with a QIAquick Gel Extraction Kit (Qiagen). 25 ng of this DNA was labeled with P32 using the Multiprime DNA Labeling System (Amersham) and unincorporated radioactivity was removed with a NucTrap Probe Purification Column (Stratagene). Multiple tissue 20 northerns and a human RNA master blot were prehybridized 3 hours with 10 ml ExpressHyb Solution and added to blots. Hybridization was carried out overnight at 42°C with a 10 ml solution of probe containing a concentration of 2 x 106/ml of probe to which 1 mg of salmon sperm DNA was added 25 which had been boiled for 5 minutes and then iced 1 minute and added to 10 ml of ExpressHyb Solution (Clontech). Initial wash conditions were as follows: 2X SSC, 0.05% SDS RT for 40 minutes with several changes of solution then 0.1X SSC, 0.1% SDS at 65°C for 40 minutes, 1 solution 30 change. Blots were than exposed to film a -80°C. There was cross hybridization/background so blots were further washed at 72°C then 65°C with 0.1% X SSC, 0.1% SDS for 1 hour each.

The results showed that Zneul is widely expressed m adult tissues. Zneul is highly expressed m heart, placenta, spleen, testis, thyroid, spinal cord and lymph node. There are at least three mRNA sizes:
1.3 kb mRNA only in brain and testis;
1.4 kb only in lymph node;
1.5 + 1.7 kb in multiple tissues; and
2.4 kb only in placenta.
Example 3
Chromosomal Assignment and Placement of Zneul.
Zneul was mapped to chromosome 9 using the 15 commercially available "GeneBridge 4 Radiation Hybrid Panel" (Research Genetics, Inc., Huntsville, AL) . The GeneBridge 4 Radiation Hybrid Panel contains PCRable DNAs from each of 93 radiation hybrid clones, plus two control DNAs (the HFL donor and the A23 recipient). A publicly 20 available WWW server (http://www-genome.wi.mit.edu/cgi-bin/contig/rhmapper.pi) allows mapping relative to the Whitehead Institute/MIT Center for Genome Research's radiation hybrid map of the human genome (the "WICGR" radiation hybrid map) which was constructed with the 25 GeneBridge 4 Radiation Hybrid Panel.
For the mapping of Zneul with the "GeneBridge 4 RH Panel", 20 }il reactions were set up in a PCRable 96-well microtiter plate (Stratagene, La Jolla, CA) and used m a 30 "RoboCycler Gradient 96" thermal cycler (Stratagene). Each of the 95 PCR reactions consisted of 2 pi 10X KlenTaq PCR" reaction buffer (CLONTECH Laboratories, Inc., Palo Alto,
Printed from Mimosa
CA) , 1.6 ill dNTPs mix (2.5 mM each, PERKIN-ELMER, Foster City, CA), 1 pi sense primer, SEQ ID NO: 6, 1 pi antisense primer, SEQ ID NO: 7, 2 pi "RediLoad" (Research Genetics, Inc., Huntsville, AL), 0.4 pi 50X Advantage KlenTaq 5 Polymerase Mix (Clontech Laboratories, Inc.), 25 ng of DNA from an individual hybrid clone or control and x pi ddH20 for a total volume of 20 pi. The reactions were overlaid with an equal amount of mineral oil and sealed. The PCR cycler conditions were as follows: an initial 1 cycle 5 10 minute denaturation at 95°C, 35 cycles of a 1 minute denaturation at 95°C, 1 minute annealing at 70°C and 1.5 minute extension at 72°C, followed by a final 1 cycle extension of 7 minutes at 72°C. The reactions were separated by electrophoresis on a 2% agarose gel (Life 15 Technologies, Gaithersburg, MD).
The results showed that Zneul maps 529.80 cR_3000 from the top of the human chromosome 9 linkage group on the WICGR radiation hybrid map, 7.90 cR_3000 distal of 20 framework marker D9S158. This positions Zneul in the
9q34.3 region on the integrated LDB chromosome 9 map (The Genetic Location Database, University of Southhampton, WWW server: http://cedar.genetics. soton.ac.uk/public_html/) .
