Ntrk1 Gene Summary [Rat]
Enables several functions, including GPI-linked ephrin receptor activity; nerve growth factor binding activity; and neurotrophin p75 receptor binding activity. Involved in several processes, including detection of stimulus involved in sensory perception of pain; nervous system development; and positive regulation of cell communication. Acts upstream of or within cellular response to growth factor stimulus and protein autophosphorylation. Located in several cellular components, including cell surface; endosome; and neuronal cell body. Part of protein-containing complex. Used to study Parkinsonism; glaucoma; and myofascial pain syndrome. Biomarker of several diseases, including colitis; diabetic neuropathy; glaucoma; periodontitis; and retinal detachment. Human ortholog(s) of this gene implicated in Alzheimer's disease; hereditary sensory neuropathy; hereditary sensory neuropathy type 4; and schizophrenia. Orthologous to human NTRK1 (neurotrophic receptor tyrosine kinase 1). [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 Ntrk1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
