Staurosporine blocked thrombin-induced PKC phosphorylation and proteolysis of adducin.
Preincubation of platelets with the kinase inhibitor staurosporine (10 minutes) completely blocked thrombin-induced PKC phosphorylation of adducin (B) and proteolysis (C). Thrombin concentration, 1 U/mL; CaCl2, 2.5 mM.
