Abstract

PURPOSE:To provide a DNA fragment coding for regucalcin derived from a hepatocellular cytoplasm and fulfilling the role as a control factor in a intracellular informational transmitting system with Ca<2+> and mass-producing the regucalcin useful as a reagent for research and a clinical testing agent. CONSTITUTION:This new DNA fragment coding for regucalcin derived from a hepatocellular cytoplasm is expressed by an amino acid sequence represented by the formula. The DNA fragment is obtained by extracting a liver from a Wistar strain male rat, recovering an mRNA according to a guanidinium thiocyanate method, passing, the resultant recovered mRNA through an oligo(dT) cellulosic column, separating the mRNA, reacting a reverse transcriptase therewith, synthesizing a cDNA, then preparing a cDNA library according to a conventional method, screening the prepared library with an antiregucalcin antibody, recovering a DNA from a positive clone and treating the obtained DNA with a restriction enzyme. Thereby, the regucalcin can be mass-produced by a transformant cell containing the DNA fragment.

In contrast, regucalcin is a new Ca 2+ -binding protein isolated from rat liver cytoplasm. Unlike calmodulin, regucalcin is an acidic protein with an isoelectric point pI 5.20 which is remarkably present in the liver, and its Ca 2+ binding constant is 4.19 × 10 5 M −1 , and 6 to
It has 7 high-affinity Ca 2+ binding sites and contains 34% α-helix structure. When Ca 2+ binds to regucalcin, the structure of regucalcin becomes loose. Moreover, regucalcin is known to controlling the activation of the enzyme in the liver by Ca 2+, it plays a role as a regulator of intracellular signal transduction system by Ca 2+. Furthermore, it was found that the amount of regucalcin in the hepatocytes was reduced and the substance was leaked into the serum in the case of carbon tetrachloride liver injury, suggesting a relationship with the pathological condition of the liver.

(manufactured by Cal Co.) was used to determine the entire nucleotide sequence of the cDNA insert. That is, the plasmid DNA was cleaved with Eco RI, the fragment was treated with alkaline denaturation, and then a primer was added and annealed. 35 SdCTP, 0.1M

Divide equally into ddATP, ddGTP, ddTTP,
ddCTP was added and incubated at 37 ° C for 5 minutes.
These were separated by acrylamide gel electrophoresis and subjected to autoradiography to read the nucleotide sequence. SEQ ID NO: 3 shows the entire nucleotide sequence of the cDNA insert.
A of the translation initiation codon ATG was found at the 80th position from the 5'end, and a termination codon TAA was found at the 977th to 979th positions. It was found that when the base sequence corresponding to this open reading frame was converted into amino acids, a total of 299 amino acids were encoded. The resulting amino acid sequence is also shown in SEQ ID NO: 3. The molecular weight of regucalcin calculated from this was 33,388. This value was consistent with the molecular weight of purified regucalcin calculated by SDS polyacrylamide gel electrophoresis. It was found that the base sequence of the cDNA encoding this regucalcin did not match the base sequence registered in the database of EMBL or Genbank, and was different from the existing one. The homology was low when compared with the amino acid sequences of other Ca 2+ -binding proteins (calmodulin, 13.3%; calbinden-D28K, 16.
