NCI: The hepatocyte growth factor receptor, also called c-Met, is activated by HGF and stimulates proliferation of hepatocytes and other cell types. Mutated forms of the HGF receptor are associated with oncogenesis and metastasis, making the HGF receptor a potential therapeutic target for cancer drugs. Changes in cell motility, cell shape, adhesion, resistance to apoptosis, and anchorage independent growth all contribute to the role of c-Met in cancer. The HGF receptor is a heterodimer with tyrosine kinase activity and associates with a multiprotein complex involved in downstream signal transduction. The HGF receptor can associate with several different signaling systems, including src, Grb2/SOS, PI3 kinase and Gab1. One of the major substrates of the activated HGF receptor tyrosine kinase is the adaptor protein Gab1. Gab1 interacts with Crk and CrkL, two proteins with SH2 and SH3 protein interaction domains that couple to signaling further downstream. The actions of HGF on paxillin, DOCK180, and Rap1, mediat
