title: Cloning and expression of multiple protein kinase C cDNAs.
abstract: Three different protein kinase C related cDNA clones were isolated from a rat brain cDNA library and designated PKC-I, PKC-II, and PKC-III. These each encode very similar, but distinct, polypeptides that contain a region homologous with other protein kinases. COS cells transfected with either PKC-I or PKC-II specifically bind at least 5-fold more 3H-PDBu (phorbol ester) than control cells. An increase in Ca2+, phosphatidylserine, and diacylglycerol/phorbol-ester-dependent protein kinase activity is also observed in COS cells transfected with either PKC-I or PKC-II. The physiological implications of the discovery of three protein-kinase-C-related cDNAs are discussed.
