Polypeptide gene cDNA, vector containing said cDNA, host cells transformed with said vector, method of producing said polypeptide, DNA encoding said polypeptide

摘要

cDNAs were synthesized from the mRNA isolated from the mantle epithelial tissue of pearl oyster (Pinctada fucata) using reverse transcriptase and joined to a vector to give a cDNA library. A cDNA inserted in this cDNA library was caused to be expressed in Escherichia coli, for instance, to give a polypeptide corresponding to said cDNA. This polypeptide serves as a novel ingredient of cosmetic compositions, for instance.
