since ca2+-activated , phospholipid-dependent protein kinase ( c-kinase ) is activated by diacylglycerol and is responsible for 40 k protein phosphorylation ( kawahara , y. , takai , y. , minakuchi , r. , sano , k. , & nishizuka , y . ( 1980 ) biochem . biophys . res . commun . 97 , 309-317 ) , the results suggest that in platelets both cyclic amp and cyclic gmp may serve as inhibitors of c-kinase by counteracting the receptor-linked pi breakdown probably through the actions of cyclic nucleotide-dependent protein kinases .
