Grb2 recruits the docking protein Gab1 which is tyrosine phosphorylated by EGFR or FGFR leading to recruitment and activation of the PI3K-Akt cell survival pathway.
Recruitment of PI 3-kinase by Gab1 results in a positive-feedback loop mediated by binding of the PH domain of Gab1 to the product of PI3-kinase activation phosphatidylinositol-345-triphosphate.
