Chicken TrkA Polyclonal Antibody | anti-TrkA antibody
TrkA Antibody FITC-Conjugated
Immunoprecipitation: 1:200
Western Blot: 1:500
Receptor tyrosine kinase involved in the development and the maturation of the central and peripheral nervous systems through regulation of proliferation, differentiation and survival of sympathetic and nervous neurons. High affinity receptor for NGF which is its primary ligand, it can also bind and be activated by NTF3/neurotrophin-3. However, NTF3 only supports axonal extension through NTRK1 but has no effect on neuron survival. Upon dimeric NGF ligand-binding, undergoes homodimerization, autophosphorylation and activation. Recruits, phosphorylates and/or activates several downstream effectors including SHC1, FRS2, SH2B1, SH2B2 and PLCG1 that regulate distinct overlapping signaling cascades driving cell survival and differentiation. Through SHC1 and FRS2 activates a GRB2-Ras-MAPK cascade that regulates cell differentiation and survival. Through PLCG1 controls NF-Kappa-B activation and the transcription of genes involved in cell survival. Through SHC1 and SH2B1 controls a Ras-PI3 kinase-AKT1 signaling cascade that is also regulating survival. In absence of ligand and activation, may promote cell death, making the survival of neurons dependent on trophic factors. Isoform TrkA-III is resistant to NGF, constitutively activates AKT1 and NF-kappa-B and is unable to activate the Ras-MAPK signaling cascade. Antagonizes the anti-proliferative NGF-NTRK1 signaling that promotes neuronal precursors differentiation. Isoform TrkA-III promotes angiogenesis and has oncogenic activity when overexpressed.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a member of the neurotrophic tyrosine kinase receptor (NTKR) family. This kinase is a membrane-bound receptor that, upon neurotrophin binding, phosphorylates itself and members of the MAPK pathway. The presence of this kinase leads to cell differentiation and may play a role in specifying sensory neuron subtypes. Mutations in this gene have been associated with congenital insensitivity to pain, anhidrosis, self-mutilating behavior, mental retardation and cancer. Alternate transcriptional splice variants of this gene have been found, but only three have been characterized to date. [provided by RefSeq, Jul 2008]
Uniprot Description
TrkA: a receptor tyrosine kinase of the Trk family. High affinity receptor for nerve growth factor, neurotrophin-3 and neurotrophin-4/5 but not brain- derived neurotrophic factor. Known substrates include Shc, PI-3K, and PLC-gamma-1. Has a crucial role in the development and function of the nociceptive reception system. Two splice variant isoforms have been described.

Product Notes
The TrkA ntrk1 (Catalog #AAA5400173) is an Antibody produced from Chicken and is intended for research purposes only. The product is available for immediate purchase. The TrkA Antibody FITC-Conjugated reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's TrkA can be used in a range of immunoassay formats including, but not limited to, ELISA (EIA), Immunohistochemistry (IHC), Immunoprecipitation (IP), Western Blot (WB). ELISA: 1:10,000 Immunoprecipitation: 1:200 Western Blot: 1:500. Researchers should empirically determine the suitability of the TrkA ntrk1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "TrkA, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
