|Description: High affinity nerve growth factor receptor precursor (EC 18.104.22.168)(Neurotrophic tyrosine kinase receptor type 1) (TRK1-transformingtyrosine kinase protein) (p140-TrkA) (Trk-A).|
Ensembl ID: ENSG00000198400
UniprotKB/SwissProt: NTRK1_HUMAN (P04629)
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.
