Description:
Binding of scatter factor (SF)/hepatocyte growth factor (HGF) to the c Met receptor tyrosine kinase (RTK) triggers receptor dimerization and phosphorylation on multiple residues within the juxtamembrane, catalytic core and cytoplasmic tail domains, thereby regulating receptor internalization, catalytic activity and multisubstrate docking. c Met contains three tyrosines (Tyrx- x-x-Tyr-Tyr motif) within the activation loop of the catalytic domain, for which phosphorylation of all three (tyrosines 1230, 1234, and 1235) is required for full activation. Activation of the c Met/HGF receptor results in binding and/or phosphorylation of many intracellular signaling proteins including multiple adaptor proteins (e.g., Grb2, Shc, Cbl, Crk, cortactin, paxillin, and GAB1), and a variety of other signal transducers (e.g., PI 3-kinase, FAK, Src, ERK1&2, JNK1&2, PLC gamma, and STAT3). Tyr1349 of c Met is one of the primary docking sites for PI 3-kinase and GAB1. The phosphorylation of tyrosines 1349 and 1356 serves as a priming mechanism for protein binding.
