The tyrosine-protein phosphatase SHP2 is a positive effector of EGFR signalling. SHP2 inhibits the tyrosine-dependent translocation of RasGAP (catalyses Ras inactivation) to the plasma membrane, thereby keeping it away from Ras-GTP (its substrate). This inhibition is achieved by the dephosphorylation of a RasGAP binding site on the EGF receptor.
