TrkA belongs to the Trk proto-oncogene family and is expressed mainly in central and peripheral nervous systems. When TrkA binds to NGF, it autophosphorylates tyrosine residues like-Tyr490, Tyr674, Tyr675, Tyr751, and Tyr785 and subsequently activates many downstream effector proteins. Defects in TrkA lead to congenital insensitivity to pain with anhidrosis. Anti-phospho-TrkA (pTyr490) antibody can be used in immunocytochemistry (1:100, using cultured cells). It is also useful in identifying endogenous levels of phosphorylated Tyr490 in TrkA, TrkB and TrkC. Rabbit anti- phospho-TrkA (pTyr490) antibody is reactive in mouse, human and rat.
Immunogen
synthetic phosphopeptide Tyr490 corresponding to residues surrounding Tyr490 of human TrkA, conjugated to KLH. This sequence is highly conserved in TrkB and TrkC.
Application
Anti-phospho-TrkA (pTyr490) antibody can be used in immunoprecipitation, immunoblotting and immunohistochemistry. It may also be used in western blotting when diluted to ratio of 1:1000 for NGF-treated PC12 cells.
Physical form
Solution in 10 mM sodium HEPES, pH 7.5, and 150 mM sodium chloride containing 100 μg/ml bovine serum albumin and 50% glycerol.

The adapter protein SH2B1 (SH2-B, PSM) is recruited to multiple ligand-activated receptor tyrosine kinases, including the receptors for nerve growth factor (NGF), insulin, and IGF-I as well as the cytokine receptor-associated Janus kinase family kinases. In this study, we examine
Congenital insensitivity to pain with anhidrosis (CIPA; MIM 256800) is an autosomal-recessive disorder characterized by recurrent episodes of unexplained fever, anhidrosis (absence of sweating) and absence of reaction to noxious stimuli, self-mutilating behaviour and mental retardation.
