Because phosphorylation of protein kinase C (PKC) may provide a mechanism for regulation of this enzyme, we have examined the ability of two other kinases to phosphorylate PKC. Our results show that casein kinase 1 (CK-1), but not casein kinase 2 (CK-2), can phosphorylate PKC in the absence of Ca2+ and phospholipids. The 32P incorporation into PKC in the presence of Ca2+ and phospholipids is also enhanced by CK-1. © 1989.
