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.
Immunogen
A synthetic peptide from the extracellular domain of human TrkA conjugated to an immunogenic carrier protein was used as the antigen.
