protein_function: Plays a role in the regulation of the translocation ofGLUT4 to the cell surface in adipocytes and skeletal muscle cellsin response to insulin, probably by regulating RAB31 activity, andthereby contributes to the regulation of insulin-dependent glucoseuptake (By similarity). Low affinity receptor which can bind toNGF, BDNF, NT-3, and NT-4. Can mediate cell survival as well ascell death of neural cells. Necessary for the circadianoscillation of the clock genes ARNTL,BMAL1, PER1, PER2 and NR1D1in the suprachiasmatic nucleus (SCN) of the brain and in liver andof the genes involved in glucose and lipid metabolism in theliver..
Nerve growth factor receptor (NGFR) is also referred to as p75(NTR) because of its ability to bind at low affinity not only to NGF, but also other neurotrophins including brain-derived neurotrophic factor (BDNF), neurotrophin-3 and neurotrophin-4,5. The nerve growth factor receptor gene is at human chromosome region 17q12-17q22, distal to the chromosome 17 breakpoint in acute leukemias. The neurotrophin receptor p75(NTR), a tumor necrosis factor receptor superfamily member expressed in hepatic stellate cells after fibrotic and cirrhotic liver injury in humans, is a regulator of liver repair. In mice, depletion of p75(NTR) exacerbated liver pathology and inhibited hepatocyte proliferation in vivo. In addition, it is showed that neurotrophins activate p75(NTR) to induce apoptosis through the induction of the sphingomyelin (SM) cycle and increased production of ceramide. Overexpression of p75(NTR) is also found to activate the SM pathway.
