Tdo2 Gene Summary [Mouse]

Predicted to enable several functions, including heme binding activity; oxygen binding activity; and tryptophan 2,3-dioxygenase activity. Predicted to be involved in L-tryptophan catabolic process to acetyl-CoA; L-tryptophan catabolic process to kynurenine; and protein homotetramerization. Is expressed in cerebellum; liver; male reproductive gland or organ; and small intestine. Human ortholog(s) of this gene implicated in Gilles de la Tourette syndrome and familial hypertryptophanemia. Orthologous to human TDO2 (tryptophan 2,3-dioxygenase). [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 mouse Tdo2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
