Abstract:
:Binding of [3H]-staurosporine to different protein kinases was time-dependent, reversible and saturable. Scatchard analysis of saturation isotherms indicated one class of binding sites for [3H]-staurosporine with dissociation constants (KD) of 9.6, 2.0, 3.0 and 7.4 nM for protein kinase C, cAMP-dependent protein kinase, tyrosine protein kinase and calcium/calmodulin-dependent protein kinase respectively. [3H]-staurosporine binding was fully displaced by unlabelled staurosporine or the related compound K-252a whereas other protein kinase inhibitors (H-7, H-8 and W-7) did not compete with [3H]-staurosporine. These data confirm that sataurosporine shows no selectivity for different protein kinases and suggest the putative existence of distinct, specific binding sites for [3H]-staurosporine on these enzymes.
