NGFR (nerve growth factor receptor), also known as Low affinity neurotrophin receptor p75NTR and CD271, is a single-pass type I transmembrane glycoprotein in the TNF receptor superfamily (TNFRSF16).  The extracellular region contains four cysteine­rich domains and binds NGF, BDNF, NT­3 and NT­4 approximately equally with low affinity. The cytoplasmic region contains a death domain (DD). NGFR is widely expressed during development and in the adult. Expression has been detected in both neuronal and non­neuronal cells. NGFR was originally reported to function as a positive regulator of TrkA, a high- affinity nerve growth factor receptor. NGFR has also been shown to signal by itself. Depending on its cellular environment, NGFR has now been shown to regulate cell migration, gene expression and to mediate apoptosis. Recombinant NGF R/Fc chimera binds NGF with high affinity and is a potent NGF antagonist. Naturally occurring truncated NGF R containing the extracellular domain and lacking the transmembrane or intracellular domain has been detected in vivo in urine, plasma and in amniotic fluid of humans and animals. NGFR is also necessary for the circadian oscillation of the clock genes in the suprachiasmatic nucleus of the brain and in liver and of the genes involved in glucose and lipid metabolism in the liver. It may plays a role in the regulation of the translocation of GLUT4 to the cell surface in adipocytes and skeletal muscle cells in response to insulin and thereby contributes to the regulation of insulin-dependent glucose uptake.
