UniProt ID


The p75NTR receptor is a member of the TNF receptor superfamily. p75NTR, like all the superfamily members is a type I transmembrane protein with tandem cysteine-rich domains in the extracellular portion and a intracellular death domain. p75NTR binds its ligands as a homodimer but can also form heterodimers with other receptors such as TrkA, TrkB, TrkC, Nogo receptor and sortilin. The precise multimeric receptor complex formed between p75NTR and the other receptors will determine the ligand being recognized (see below) and the biological response to its binding.As it name implies, p75NTR binds all the neurotrophins (NGF, BDNF, NT-3 and NT-4) with similar nM affinities. Co-expression of p75NTR with the Trk receptors enhances the ability to bind and respond to the specific neurotrophin and induces cell survival. On the other hand, it has recently been demonstrated that p75NTR binds with high affinity to the unprocessed form of NGF (proNGF) probably as a complex with sortilin and this leads to cell death by apoptosis. Finally, a multimeric complex of p75NTR and Nogo receptor binds myelin proteins such as Nogo-66, MAG and OmgP resulting in inhibition of axonal growth.Abgent has now developed a new antibody specific for the p75NTR (#AG1417). The antibody was raised against a highly conserved epitope located in the stalk domain of the human p75NTR extracellular region. The chosen epitope makes this antibody highly suited for several applications including indirect flow cytometry, immunocytochemistry, immunohistochemistry and western blot. The antibody works equally well in mouse and rat samples.

Western blot analysis of normal rat tissue (right) and in human cancer cell lines (left): p75<sup>NTR</sup> is visualized with Anti-Human p75<sup>NTR</sup> (extracellular) antibody ( APR12426G), (1:200). Note that human cancer cell lines from hemapoietic origin show high p75<sup>NTR</sup> expression, while cell lines from prostate and colon cancer origin show lower levels. Interestingly, p75<sup>NTR</sup> from rat (right blot and the C6 cell line) and human (left blot) samples run with a different apparent MW, probably due to species-specific differential glycosylation.
