Trk Receptor

TrkA (Tropomyosin related kinase receptor) is a protein that in humans is encoded by the NTRK1 gene. TrkA is a member of the neurotrophic tyrosine kinase receptor (NTKR) family. TrkA is a membrane-bound receptor that, upon neurotrophin binding, phosphorylates itself (autophosphorylation) and members of the MAPK pathway. TrkA is the high affinity catalytic receptor for the neurotrophin, Nerve Growth Factor, which include neuronal differentiation and avoidance of programmed cell death. The presence of TrkA leads to cell differentiation and may play a role in specifying sensory neuron subtypes. Mutations in TrkA gene have been associated with congenital insensitivity to pain with anhidrosis, self-mutilating behavior, mental retardation and cancer.

TrkB has the highest affinity to the binding of brain-derived neurotrophic factor (BDNF) and NT-4. BDNF is a growth factor that has important roles in the survival and function of neurons in the central nervous system. The binding of BDNF to TrkB receptor causes many intercellular cascades to be activated, which regulate neuronal development and plasticity, long-term potentiation, and apoptosis.

TrkC is ordinarily activated by binding with NT-3 and has little activation by other ligands. (TrkA and TrkB also bind NT-3, but to a lesser extent). TrkC is mostly expressed by proprioceptive sensory neurons.
