|Immunogen||A synthetic peptide from the extracellular domain of human TrkA (High affinity nerve growth factor receptor, NTRK1, p140-TrkA, Trk-A) conjugated to an immunogenic carrier protein was used as the immunogen.|
|Description||FUNCTION: Required for high-affinity binding to nerve growth factor (NGF), neurotrophin-3 and neurotrophin-4/5 but not brain-derived neurotrophic factor (BDNF). Known substrates for the Trk receptors are SHC1, PI 3-kinase, and PLC-gamma-1. Has a crucial role in the development and function of the nociceptive reception system as well as establishment of thermal regulation via sweating. Activates ERK1 by either SHC1- or PLC-gamma-1-dependent signaling pathway. CATALYTIC ACTIVITY: ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. SUBUNIT: Exists in a dynamic equilibrium between monomeric (low affinity) and dimeric (high affinity) structures. Binds SH2B2. Interacts with SQSTM1 which bridges NTRK1 to NGFR. Interacts with NGFR and ARMS. Can form a ternary complex with NGFR and ARMS and this complex is affected by the expression levels of ARMS. An increase in ARMS expression leads to a decreased association of NGFR and NTRK1. SUBCELLULAR LOCATION: Cell membrane; Single-pass type I membrane protein. Note: Endocytosed to the endosomes upon treatment of cells with NGF. TISSUE SPECIFICITY: Isoform Trka-II is primarily expressed in neuronal cells; isoform Trka-I is found in non-neuronal tissues. Also known as: High affinity nerve growth factor receptor, NTRK1, p140-TrkA, Trk-A, Neurotrophic tyrosine kinase receptor type 1, Slow nerve growth factor receptor.|
|Specificity||Appears to be specific for TrkA.|
|Application Notes||IHC, WB. A concentration of 10-50 µg/ml is recommended. The optimal concentration should be determined by the end user.|
|Storage||Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.|
