Background InformationBDNF/NT-3 growth factors receptor (UniProt: Q16620; also known as EC:2.7.10.1, GP145-TrkB, Trk-B, Neurotrophic tyrosine kinase receptor type 2, TrkB tyrosine kinase, Tropomyosin-related kinase B) is encoded by the NTRK2 (also known as TRKB) gene (Gene ID: 4915) in human. TrkB is a single-pass type I membrane protein that is internalized to endosomes upon ligand-binding. It is synthesized with a signal peptide (aa 1-31) that is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 32-430), a transmembrane domain (aa 431-454), and a cytoplasmic domain (aa 455-822). TrkB is a receptor tyrosine kinase that is involved in the development and maturation of the central and the peripheral nervous systems through regulation of neuron survival, proliferation, migration, differentiation, and synapse formation and plasticity. In the central nervous system, its expression is observed in the cerebral cortex, hippocampus, thalamus, choroid plexus, granular layer of the cerebellum, brain stem, and spinal cord. In the peripheral nervous system, it is expressed in many cranial ganglia, the ophthalmic nerve, the vestibula, and multiple facial structures. Upon ligand-binding, it undergoes homodimerization, autophosphorylation, and activation. It can then recruit, phosphorylate and/or activate several downstream effectors including SHC1, FRS2, SH2B1, SH2B2 and PLCG1 that regulate distinct overlapping signaling cascades. TrkB is also reported to play a role in neutrophin-dependent calcium signaling in glial cells and mediate communication between neurons and glia. Following binding of BDNF to TrkB receptor, Tyrosine 816 is phosphorylated, which allows the binding of phospholipase C gamma and activation of signaling cascade.
