Summary: Predicted to enable several functions, including heme binding activity; oxygen binding activity; and tryptophan 2,3-dioxygenase activity. Predicted to be involved in indolalkylamine metabolic process 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).

Study demonstrated that n-butylidenephthalide (n-BP)functions by regulating the early part of the kynurenine pathway through the downregulation of tryptophan 2, 3-dioxygenase (TDO2), which decreases the downstream neurotoxic product, quinolinic acid (QA). Findings indicate a correlation between n-BP, TDO2, QA, calpain, and toxic fragment formation.

Data suggest that Indoleamine 2,3-dioxygenase 1 (IDO1) appears to be a potential hallmark of liver lesions, and its deficiency protects mice from CCl4-induced fibrosis mediated by Th17 cells down-regulation and tryptophan 2,3-dioxygenase (TDO) compensatory increase.

Data suggest that high-fat diet (HFD) alters regulation of expression of sirtuins (Sirt4 and Sirt7) and enzymes in NAD biosynthetic pathway (Tdo2 and Nnmt); these alterations are more prominent in liver as compared to white adipose tissue or skeletal muscle; Tdo2 and Nnmt may serve as markers of HFD consumption.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
