The inhibitory effects of Ca2+-binding proteins on tyrosine phosphorylation of p36 protein isolated from bovine intestinal epithelium by immunoprecipitated p130fps were investigated. S-100 protein dose dependently inhibited the p36 phosphorylation, and calmodulin weakly depressed the phosphorylation, whereas parvalbumin and troponin C had no significant effects. The S-100 preparation purified from bovine brain did not contain phosphatase activity or ATPase activity. The concentration of ATP did not affect the S-100-mediated inhibition of phosphorylation but the substrate protein, p36, reversed the inhibition. S-100 similarly inhibited the tyrosine phosphorylation of p36 by p60src but did not affect the p36 phosphorylation by protein kinase C. S-100 inhibited the tyrosine kinase activity of p130fps using the other substrates tested as well. These results suggest that S-100 interacts with the substrate binding site of retroviral tyrosine-specific protein kinases and may play a regulatory role in the tyrosine phosphorylation.
