NTRK1 Antibody – Rabbit Polyclonal

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]

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.
