HGF binds to proto-oncogene c-Met receptor and activates a tyrosine kinase signaling cascade. HGF precursor is cleaved by serine protease to α (69 kD) and β (34 kD) chains which form a disulfide bond to produce the active heterodimer. HGF α chain contains an N-terminal hairpin and 4 kringle domains. The kringle domain participates in protein-protein interaction and its structure is of a large loop which is stabilized by 3 Cys-Cys bonds. HGF β chain is catalytically inactive serine protease-like. HGF NK1 - a natural splice variant is comprised of residues 28-210 containing the N-terminus and the first kringle domain of HGF. HGF NK2 variant is comprised of residues 28-289 containing the N-terminus and the first 2 kringle domains of HGF. See also Hepatocyte growth factor receptor. Relevance High levels of HGF are associated with liver diseases, lung diseases, acute cardiac infraction, vascular diseases, renal failure, neurologic diseases like Alzheimer Disease, pancreatic diseases, several types of cancer and diabetes type II. HGF administration can reverse liver chirrosis.
