In the DE-52 fraction 19 of the crude cytosolic extract of Saccharomyces cerevisiae, the 31-kDa endogenous substrate(s) of protein kinase C were detected by SDS-polyacrylamide gel electrophoresis and autoradiography. Phosphorylation of the substrate(s) depended on Ca2+, phosphatidylserine and diacylglycerol. It was also enhanced by phosphatidylinositol, phosphatidylethanolamine and phosphatidylglycerol (dioleoyl), but inhibited by arachidonic acid and sphingosine.
