  • Overview of NTRK2 molecular targets


    Tropomyosin kinase receptor B (TrkB), also known as tyrosine kinase receptor B, is a receptor for brain-derived neurotrophic factor (BDNF) and a member of the neurotrophin tyrosine kinase receptor (NTRK) family. This kinase is a membrane-bound receptor expressed exclusively in neurons of the central nervous system. TrkB mediates many of the actions of neurotrophins such as BDNF, neurotrophin-4 (NT-4), and neurotrophin-3 (NT-3), including neuronal differentiation and survival. In the extracellular domain, it has two distinct regions that bind BDNF with high affinity. Once bound to neurotrophins, TrkB itself and downstream members of the associated signaling pathways become phosphorylated. TrkB plays an important role in tumorigenesis and metastasis, and mutations in this gene are associated with obesity and mood disorders. Therefore, BDNF/TrkB signaling is considered a potential target for the treatment of schizophrenia.
