摘要: We have examined the interaction between platelet-derived growth factor (PDGF) receptor and three src family tyrosine kinases, pp60c-src, p59fyn, pp62c-yes. The kinase activities of all enzymes were elevated after PDGF stimulation quiescent fibroblasts, coincident with association kinases other proteins. presence a protein 81-85 kd in these complexes correlated detection phosphatidylinositol (PI) activity (previously described to associate both pp60c-src-middle T antigen). These results suggest that physiological response involves not only serine/threonine lipid phospholipase, but also kinases.
