Nerve Growth Factor Receptor Definition
Nerve growth factor receptor (NGFR) is also referred to as p75(NTR) due to its molecular mass and its ability to bind at low affinity not only NGF, but also other neurotrophins, including brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NTF3), and neurotrophin-4/5 (NTF5). NGFR was the first member of the large superfamily of tumor necrosis factor receptors. The identification of this superfamily helped elucidate some of the biologic functions of NGFR, including its ultimate involvement in the nuclear factor kappa-B (NFKB) and apoptosis pathways. As a monomer, NGFR binds NGF with low affinity. Higher affinity binding is achieved by association with higher molecular mass, low-affinity neurotrophin receptors, namely the tropomyosin receptor kinases, TRKA (NTRK1), TRKB (NTRK2), and TRKC (NTRK3).
