Disease

HGF_HUMAN Defects in HGF are the cause of deafness autosomal recessive type 39 (DFNB39) [MIM:608265. A form of profound prelingual sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information.^[1]

Function

HGF_HUMAN Potent mitogen for mature parenchymal hepatocyte cells, seems to be a hepatotrophic factor, and acts as a growth factor for a broad spectrum of tissues and cell types. Activating ligand for the receptor tyrosine kinase MET by binding to it and promoting its dimerization.^[2] ^[3]

Publication Abstract from PubMed

Stimulation of hepatocyte growth factor (HGF) signaling through the Met receptor is an attractive approach for promoting tissue repair and preventing fibrosis. Using structure-guided peptide phage display combined with an activity-based sorting strategy, we engineered allosteric activators of zymogen-like pro-HGF to bypass proteolytic activation and reversibly stimulate pro-HGF signaling through Met. Biochemical, structural and biological data showed that zymogen activator peptides (ZAPtides) potently and selectively bind the activation pocket within the serine protease-like beta-chain of pro-HGF and display titratable activation of pro-HGF-dependent Met signaling, leading to cell survival and migration. To further demonstrate the versatility of our ZAPtide platform, we identified allosteric activators for pro-macrophage stimulating protein and a zymogen serine protease, Protein C, which also provides evidence for target selectivity. These studies reveal that ZAPtides use molecular mimicry of the trypsin-like N-terminal insertion mechanism and establish a new paradigm for selective pharmacological activation of plasminogen-related growth factors and zymogen serine proteases.
