Summary
Enables brain-derived neurotrophic factor binding activity and brain-derived neurotrophic factor receptor activity. Involved in several processes, including brain-derived neurotrophic factor receptor signaling pathway; modulation of chemical synaptic transmission; and nervous system development. Acts upstream of or within several processes, including neurogenesis; neuronal action potential propagation; and positive regulation of peptidyl-serine phosphorylation. Located in several cellular components, including early endosome; postsynaptic density; and terminal bouton. Is expressed in several structures, including alimentary system; future brain; genitourinary system; integumental system; and nervous system. Human ortholog(s) of this gene implicated in Alzheimer's disease; autistic disorder; developmental and epileptic encephalopathy 58; major depressive disorder; and morbid obesity. Orthologous to human NTRK2 (neurotrophic receptor tyrosine kinase 2). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
