c-Met/HGFR

c-Met (hepatocyte growth factor receptor, HGFR) is a protein possesses tyrosine kinase activity. The primary single chain precursor protein is post-translationally cleaved to produce the alpha and beta subunits, which are disulfide linked to form the mature receptor. c-Met is a membrane receptor that is essential for embryonic development and wound healing. Hepatocyte growth factor (HGF) is the only known ligand of the c-Met receptor. c-Met is normally expressed by cells of epithelial origin, while expression of HGF is restricted to cells of mesenchymalorigin. Upon HGF stimulation, c-Met induces several biological responses that collectively give rise to a program known as invasive growth.
