Tph2 Gene Summary [Rat]
Predicted to enable tryptophan 5-monooxygenase activity. Involved in several processes, including cellular response to lithium ion; response to activity; and response to estrogen. Located in axon and neuronal cell body. Used to study sleep apnea. Biomarker of depressive disorder; panic disorder; and subacute delirium. Human ortholog(s) of this gene implicated in several diseases, including alcohol dependence; alcohol use disorder; anxiety disorder (multiple); autistic disorder; and drug dependence (multiple). Orthologous to human TPH2 (tryptophan hydroxylase 2). [provided by Alliance of Genome Resources, Apr 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 Tph2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
