PI3K activation by Met. (A) Table of PI3K isoforms and classes. Height PI3K isoforms divided into three classes depending on their lipid substrate, their catalytic subunit and their regulatory subunit. (B) Met, directly or indirectly, through adaptors, scaffolding molecules or other downstream signaling molecules, regulates class I PI3K activation. Dashed line: not demonstrated downstream of Met. Ptdlns(4,5)P2, phosphatidylinositol-4,5-bisphosphate; Ptdlns, phosphatidylinositol; Ptdlns4P, phosphatidylinositoi-4-phosphate; HGF, hepatocyte growth factor; PI3K, p110-p85; Grb2, growth factor receptor bound protein 2; She, Sarcoma (SRC) homology-2-containing; Gab1, Grb2-associated binding protein 1; SHP2, Src homology domain-containing 5′ inositol phosphatase 2; p120, p120-ras-GTPase activating protein; SOS, son of sevenless; FAK, focal adhesion kinase.
