Analyses of tyrosine residue - mutated PDGF receptors show that Src homology 2 domain - containing proteins including Src family kinases , phosphatidylinositol 3 - kinase , the GTPase - activating protein of Ras , the Src homology 2 domain - containing phosphatase SHP - 2 , phospholipase C - gamma , and Crk do not play a major role in mediating the PDGF - induced activation of p38 .
