Function
TrkB (tropomyosin receptor kinase B)， encoded by NTRK2, is a neurotrophic tyrosine kinase receptor that mediates the cellular actions of brain-derived neurotrophic factor (BDNF) and contributes to neuronal differentiation, neuroplasticity, and homeostasis[1][2]. Mechanistically, ligand-induced activation of full-length TrkB (TrkB.FL) triggers receptor autophosphorylation and engages intracellular signaling pathways including PI3K, MAPK/ERK, and PLCγ, thereby supporting neurotrophic responses and synaptic function[3][4]. Alternative splicing of NTRK2 generates distinct receptor isoforms, including TrkB.FL and truncated variants such as TrkB.T1, TrkB.T2, and TrkB-T-ShC, which lack the tyrosine kinase domain and therefore differ fundamentally in signaling capacity[2][5]. Compared with TrkB.FL, TrkB.T1 is the major truncated isoform in the adult brain and can negatively regulate full-length receptor signaling through dominant-inhibitory mechanisms while also exhibiting independent biological activities[5][4]. Altered TrkB isoform balance has been associated with neurodegeneration, ischemic injury, amyotrophic lateral sclerosis, spinal muscular atrophy, psychiatric disorders, and cognitive dysfunction, highlighting the importance of isoform-specific regulation in disease biology[2][6][4][7]. In experimental systems, modulation of BDNF-TrkB signaling and manipulation of TrkB isoform expression are widely used to investigate neuronal survival, differentiation, synaptic plasticity, and disease mechanisms, making TrkB a valuable target for mechanistic and translational neuroscience research[3][5][4].

Expression
Tissue_specificity:The TrkB subtype is expressed in both the central and peripheral nervous systems. In the central nervous system (CNS) , it is expressed in the cerebral cortex, hippocampus, thalamus, choroid plexus, cerebellar granular layer, brainstem, and spinal cord. In the peripheral nervous system, it is expressed in multiple cranial ganglia, the ophthalmic nerve, the vestibular system, various facial structures, the submandibular gland, and the dorsal root ganglion. The TrkB-T1 subtype is primarily expressed in the brain, but is also found in other tissues, including the pancreas, kidneys, and heart. The TrkB-T-Shc subtype is primarily expressed in the brain. -

Q16620 has 7 isomers: Q16620-1: 91999 Da (predicted); Q16620-2: 53051 Da (predicted); Q16620-3: 59167 Da (predicted); Q16620-4: 93826 Da (predicted); Q16620-5: 60994 Da (predicted); Q16620-6: 81569 Da (predicted); Q16620-7: 35332 Da (predicted).
Phosphorylated. Undergoes ligand-mediated autophosphorylation that is required for interaction with SHC1 and PLCG1 and other downstream effectors. Isoform TrkB-T-Shc is not phosphorylated;Ubiquitinated. Undergoes polyubiquitination upon activation; regulated by NGFR. Ubiquitination regulates the internalization of the receptor (By similarity) -
Subunit
Exists in a dynamic equilibrium between monomeric (low affinity) and dimeric (high affinity) structures. Interacts (phosphorylated upon activation by BDNF) with SHC1; mediates SHC1 phosphorylation and activation. Interacts (phosphorylated upon activation by BDNF) with PLCG1 and/or PLCG2; mediates PLCG1 phosphorylation and activation. Interacts with SH2B1 and SH2B2. Interacts with NGFR; may regulate the ligand specificity of the receptor (By similarity). Interacts with SORCS2; this interaction is important for normal targeting to post-synaptic densities in response to high-frequency stimulation (By similarity). Interacts (phosphorylated upon ligand-binding) with SH2D1A; regulates NTRK2. Interacts with SQSTM1 and KIDINS220 (By similarity). Interacts (phosphorylated upon ligand-binding) with FRS2; activates the MAPK signaling pathway (PubMed:10092678). Interacts with APPL1 (By similarity). Interacts with MAPK8IP3/JIP3 and KLC1; interaction with KLC1 is mediated by MAPK8IP3/JIP3 (By similarity). Interacts with SORL1; this interaction facilitates NTRK2 trafficking between synaptic plasma membranes, postsynaptic densities and cell soma, hence positively regulates BDNF signaling (By similarity). Interacts with SLITRK2 (PubMed:35840571)
