Function

Receptor tyrosine kinase involved in the development and the maturation of the central and the peripheral nervous systems through regulation of neuron survival, proliferation, migration, differentiation, and synapse formation and plasticity. Receptor for BDNF/brain-derived neurotrophic factor and NTF4/neurotrophin-4. Alternatively can also bind NTF3/neurotrophin-3 which is less efficient in activating the receptor but regulates neuron survival through NTRK2. Upon ligand-binding, undergoes homodimerization, autophosphorylation and activation. Recruits, phosphorylates and/or activates several downstream effectors including SHC1, FRS2, SH2B1, SH2B2 and PLCG1 that regulate distinct overlapping signaling cascades. Through SHC1, FRS2, SH2B1, SH2B2 activates the GRB2-Ras-MAPK cascade that regulates for instance neuronal differentiation including neurite outgrowth. Through the same effectors controls the Ras-PI3 kinase-AKT1 signaling cascade that mainly regulates growth and survival. Through PLCG1 and the downstream protein kinase C-regulated pathways controls synaptic plasticity. Thereby, plays a role in learning and memory by regulating both short term synaptic function and long-term potentiation. PLCG1 also leads to NF-Kappa-B activation and the transcription of genes involved in cell survival. Hence, it is able to suppress anoikis, the apoptosis resulting from loss of cell-matrix interactions. Isoform GP95-TRKB may also play a role in neutrophin-dependent calcium signaling in glial cells and mediate communication between neurons and glia.

Activity summary

TrkB also known as Neurotrophic Tyrosine Kinase Receptor Type 2 (NTRK2) is a cell surface receptor with a mass of approximately 145 kDa. It binds brain-derived neurotrophic factor (BDNF) and is widely expressed in the central nervous system particularly in areas like the hippocampus cortex and cerebellum. TrkB belongs to the family of receptor tyrosine kinases functioning by catalyzing the transfer of a phosphate group from ATP to specific tyrosine residues on substrate proteins in the receptor triggering downstream signaling cascades.

Biological function summary

TrkB plays essential roles in neuronal survival differentiation and synaptic plasticity. It acts as an important mediator for the effects of neurotrophins primarily BDNF on neurons. While TrkB itself is not part of a multi-protein complex it interacts closely with several adaptor proteins post-activation to propagate survival and proliferation signals within the neuron. These biochemical interactions greatly influence neurodevelopment and cognitive functions.

Pathways

TrkB is a pivotal player in both the MAPK/ERK and PI3K/AKT pathways. Upon BDNF binding TrkB undergoes autophosphorylation triggering these pathways which are critically involved in cell survival and growth. Other proteins such as SHC1 and PLCγ interact with TrkB in these pathways extending the range of cellular responses to neurotrophin signaling facilitating processes like neuronal plasticity and memory formation.

Associated diseases and disorders

TrkB has significant implications in neurological conditions like Alzheimer's disease and depression. In Alzheimer's disease alterations in TrkB signaling can result in impaired cognitive functions and neuronal loss where it interacts with proteins like amyloid-beta contributing to disease progression. In depression dysfunctional BDNF-TrkB signaling impacts mood regulation and resilience linking TrkB with alterations in serotonin receptor signaling emphasizing its role in mood disorders.
