Ntrk3 Gene Summary [Rat]
Enables GPI-linked ephrin receptor activity. Involved in several processes, including negative regulation of astrocyte differentiation; nervous system development; and response to corticosterone. Is active in glutamatergic synapse and postsynaptic membrane. Biomarker of borna disease. Human ortholog(s) of this gene implicated in adenoid cystic carcinoma; colorectal cancer; and stomach cancer. Orthologous to human NTRK3 (neurotrophic receptor tyrosine kinase 3). [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 Ntrk3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
