    摘要: The present invention relates to the finding and construction of fish insulin-like growth factor II (IGF-II) cDNAs which can be cloned and expressed in cells. This invention also relates to the production of biologically active fish IGF-II polypeptides by a gene expression system using fish IGF-II cDNAs. The fish IGF-II cDNAs have 1977 bp which transcribe into a prepeptide (signal peptide), and B, C, A, D, E domain peptides. The fish mature IGF-II is a single polypeptide containing the NH.sub.2 -B-C-A-D-COOH domains. The mature IGF-II polypeptide is 7 kDa in weight and has 70 amino acids. The fish recombinant IGF-II CDNA can be cloned and expressed in E. coli, yeast, baculovirus, and fish cells.
