TrkA Kinase (Human) Assay/Inhibitor Screening Kit

Cat.No.: Kit-0830
Product Overview: TrkA Kinase (Human) Assay/Inhibitor Screening Kit is a single-site, non-quantitative immunoassay for kinase activity of recombinant catalytic domain of TrkA. Plates are pre-coated with a newly designed "Tyrosine kinase-substrate-1", which can be easily phosphorylated by recombinant catalytic domain of TrkA. The detector antibody is PY-39, an antibody that specifically detects the phosphotyrosine residue on "Tyrosine kinase-substrate-1".
Description: The Trk (tropomyosin receptor kinase) receptors belong to the family of receptor tyrosine kinases, and three trk genes have been identified in mammals. The TrkA protooncogene was first identified as an nerve growth factor receptor (NGFR), followed by TrkB and TrkC. Nerve growth factor (NGF) is the preferred ligand for TrkA, brain-derived neurotrophic factor (BDNF) and Neurotrophin-4/5 (NT-4/5) are preferred for TrkB, and Neurotrophin-3 (NT-3) for TrkC. These specificities are not absolute, and NT-3 is also a ligand for TrkA and TrkB. These Trk receptors are transmembrane glycoproteins of ~140 kD.They are tyrosine kinases with an extracellular ligand-binding domain containing multiple repeats of leucine-rich motifs, two cysteine clusters (C1, C2), two immunoglobulin-like domains (Ig1, Ig2), and a single transmembrane domain. The tyrosine kinase domains are highly related (~80% amino acid identity), however the extracellular domains are more divergent (~30%).
Applications: 1) Screening inhibitors or activators of recombinant catalytic domain of TrkA.2) Detecting the effects of pharmacological agents on recombinant catalytic domain of TrkA.
