p75NTR known as a cell surface receptor for NGF, BDNF, NT-3 and NT-4, is also a receptor for β-amyloid, and for the myelin axon repellant protein MAG.1,2,4,6
Binding of neurotrophins induces receptor dimerization followed by phosphorylation of receptor kinase residues and recruitment of intracellular proteins involved in signal transduction.
p75NTR functions alone, or in functional complexes with the neurotrophin receptors trkA, trkB and trkC. p75NTR signals via interaction with different transducers such as TRAF6, IRAK, and RIP-2, activating NF-κB, JNK and p38, and inactivating rhoA.1,3,6
Receptor degradation is mediated by a metalloproteinase-dependent shedding of the extracellular domain.
p75NTR binds all neurotrophins with similar nM affinity, but binds pro-neurotrophins with greater affinity, and is more potently activated by pro-neurotrophins.5
Overexpression of the intracellular domain in developing neurons induces apoptosis.
NGF-dependent association of NRIF with p75NTR contributes to pro-apoptotic signaling.7,8 β-amyloid peptide binds p75NTR and stimulates pro-apoptotic signaling by p75NTR, suggesting that the receptor may be relevant for Alzheimer's disease.9
Mouse Anti-Rat p75 NGF Receptor (extracellular) Antibody (#AN-170) is a highly specific monoclonal antibody directed against p75NTR. The antibody can be used in western blot, immunohistochemistry, and indirect flow cytometry applications. It has been designed to recognize p75NTR from rat samples only.
Mouse Anti-Rat p75 NGF Receptor (extracellular)-FITC Antibody (#AN-170-F) is directly conjugated to fluorescein isothiocyanate (FITC). This labeled antibody was specifically developed to be used in direct flow cytometry applications, especially for those that use multiple and simultaneous labeling of different markers.
