Ntrk2 Gene Summary [Rat]
Enables several functions, including brain-derived neurotrophic factor binding activity; brain-derived neurotrophic factor receptor activity; and protein homodimerization activity. Involved in several processes, including modulation of chemical synaptic transmission; positive regulation of intracellular signal transduction; and regulation of neuron projection development. Acts upstream of or within positive regulation of nuclear receptor-mediated glucocorticoid signaling pathway. Located in several cellular components, including dendritic spine; distal axon; and perikaryon. Is active in glutamatergic synapse; postsynaptic membrane; and presynapse. Used to study several diseases, including alcohol use disorder; brain disease (multiple); cognitive disorder (multiple); drug dependence (multiple); and glaucoma. Biomarker of several diseases, including alcohol use disorder; amphetamine abuse; anxiety disorder (multiple); brain disease (multiple); and neuropathy (multiple). Human ortholog(s) of this gene implicated in several diseases, including alcohol dependence; autistic disorder; developmental and epileptic encephalopathy 58; heroin dependence; and morbid obesity. Orthologous to human NTRK2 (neurotrophic receptor tyrosine kinase 2). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Ntrk2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
