title: Phosphorylation of ras oncogene product by protein kinase C.
abstract: The Harvey (H)-ras oncogene product, p21, can be phosphorylated by protein kinase C in vitro at sites distinct from the site of autophosphorylation of p21. Serine was found to be the main phosphate acceptor. Kinetic studies revealed a high apparent affinity but a much lower turnover for the phosphorylation of p21 as compared with that of the phosphorylation of histone by protein kinase C. Indirect association between protein kinase C and p21 was suggested by the co-immunoprecipitation of both proteins with either anti-protein kinase C or anti-p21 antibodies.
