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.1) Tina Garofalo, J. Biol. Chem., Dec 1998; 273: 35153. More
Trk A (phospho Tyr791) antibody was raised against a peptide sequence around phosphorylation site of tyrosine 791 (P-V-Y (p)-L-D) derived from Human Trk A.
