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. 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.

Publication Abstract from PubMed BACKGROUND: Hepatocyte growth factor (HGF) is a multipotent growth factor that transduces a wide range of biological signals, including mitogenesis, motogenesis, and morphogenesis. The N-terminal (N) domain of HGF, containing a hairpin-loop region, is important for receptor binding and the potent biological activities of HGF. The N domain is also the primary binding site for heparin or heparan sulfate, which enhances, receptor/ligand oligomerization and modulates receptor-dependent mitogenesis. The rational design of artificial modulators of HGF signaling requires a detailed understanding of the structures of HGF and its receptor, as well as the role of heparin proteoglycan; this study represents the first step towards that goal. RESULTS: We report here a high-resolution structure of the N domain of HGF. This first structure of HGF reveals a novel folding topology with a distinct pattern of charge distribution and indicates a possible heparin-binding site. CONCLUSIONS: The hairpin-loop region of the N domain plays a major role in stabilizing the structure and contributes to a putative heparin-binding site, which explains why it is required for biological functions. These results suggest several basic and/or polar residues that may be important for use in further mutational studies of heparin binding. The solution structure of the N-terminal domain of hepatocyte growth factor reveals a potential heparin-binding site.,Zhou H, Mazzulla MJ, Kaufman JD, Stahl SJ, Wingfield PT, Rubin JS, Bottaro DP, Byrd RA Structure. 1998 Jan 15;6(1):109-16.
