Expression of the cDNA encoding lipocortin‐like 39 kDa protein of guinea pig neutrophils in yeast

Abstract

The cDNA encoding lipocortin-like 39 kDa protein in guinea pig neutrophils was cloned into a yeast expression vector and the constructed plasmid was introduced into a yeast. The gene was expressed in an eukaryotic cell, yeast Saccharomyces cerevisiae and the recombinant protein was purified and characterized. The purified protein was identical with the native one with respect to the antigenicity and several biochemical properties, such as inhibitory action against phospholipase A2, Ca2+-dependent binding to acidic-phospholipids and F-actin and availability as a substrate for tyrosine kinase (EGF receptor/kinase) and protein kinase C.
