Two SH2 domains of p120 Ras GTPase - activating protein bind synergistically to tyrosine phosphorylated p190 Rho GTPase - activating protein . p120 GTPase - activating protein ( GAP ) is a negative regulator of Ras that functions at a key relay point in signal transduction pathways that control cell proliferation .
