Insulin stimulates the translocation of protein kinase C in rat adipocytes.
Insulin-induced changes in protein kinase C were examined in cytosol and membrane fractions of rat adipocytes enzymatically after Mono Q column chromatography and by immunoblotting. During a 5-20 min period of insulin treatment, cytosolic protein kinase C decrease by approximately 50%, whereas membrane protein kinase C increased nearly 2-fold. These findings suggest that insulin stimulates the translocation of protein kinase C in rat adipocytes.
