Recombinant Chicken High affinity nerve growth factor receptor (NTRK1), partial

Receptor tyrosine kinase involved in the development and the maturation of the central and peripheral nervous systems through regulation of proliferation, differentiation and survival of sympathetic and nervous neurons. High affinity receptor for NGF which is its primary ligand, it can also bind and be activated by NTF3/neurotrophin-3. Upon dimeric NGF ligand-binding, undergoes homodimerization, autophosphorylation and activation. Recruits, phosphorylates and/or activates several downstream effectors that regulate distinct overlapping signaling cascades driving cell survival and differentiation. In absence of ligand and activation, may promote cell death, making the survival of neurons dependent on trophic factors.
