Target Background

(From Uniprot)
Heme-dependent dioxygenase that catalyzes the oxidative cleavage of the L-tryptophan (L-Trp) pyrrole ring and converts L-tryptophan to N-formyl-L-kynurenine. Catalyzes the oxidative cleavage of the indole moiety.
Gene References into Functions
  1. TDO2 overexpression was related to poor prognosis and associated with cancer cell proliferation and tumor stem cells in esophageal squamous cell carcinoma. PMID: 30134247
  2. 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. PMID: 28223212
  3. the potent antimicrobial as well as immunoregulatory effects of TDO were substantially impaired under hypoxic conditions that pathophysiologically occur in vivo. This might be detrimental for the appropriate host immune response towards relevant pathogens. PMID: 27563172
  4. High TDO2 expression is associated with Colorectal Cancer. PMID: 27578919
  5. Crystal tryptophan 2,3-dioxygenase structure revealed eight residues playing critical roles in L-tryptophan oxidation. PMID: 25066423
  6. IL-1beta is suggested to stimulate tryptophan catabolism and production of IL-6 and IL-8 by increasing TDO expression in endometriosis. PMID: 24974860
  7. Identification of 12 polymorphisms in the human TDO2 promoter region, 2 of them corresponding to previously unknown single-nucleotide polymorphisms and 3 of them located in putative glucocorticoid-responsive elements. PMID: 23558111
  8. TDO is highly expressed in the brains of Alzheimer disease patients. PMID: 23630570
  9. Data suggest that T342 in hTDO has critical role in controlling substrate binding, substrate stereoselectivity, H-bonding interaction between enzyme and intermediates, and regulating the dynamics of protein structure. PMID: 22082147
  10. The data suggest that TDO uses a ring-opening mechanism during N-formylkynurenine formation, rather than Criegee or dioxetane mechanisms as previously proposed. PMID: 21892828
  11. Studies indicate that the heme dioxygenases are differentiated by their ability to catalyze the oxidation of l-tryptophan to N-formylkynurenine. PMID: 21361337
  12. subtle differences between the TDO and IDO reactions PMID: 20361220
  13. The activity and mRNA expression level of indoleamine 2,3-dioxygenase in term placentas were significantly lower in preeclampsia. Could cause dysregulation of inflammatory response intrinsic to normal pregnancy. PMID: 12634647
  14. Polymorphism of tryptophan 2,3 dioxygenase gene is associated with autism. PMID: 14755447
  15. We found that astrocytes, neurons, and microglia expressed IDO but only microglia were able to produce detectable amounts of quinolinic acid. However, astrocytes and neurons had the ability to catabolize quinolinic acid. PMID: 15390107
  16. significant mechanistic differences exist across the heme dioxygenase family, and the data are discussed within this broader framework PMID: 18370401
  17. The tyrosine 42 of recombinant human TDO is responsible for the cooperative binding of l-Trp by participating in the active site of the adjacent subunit. PMID: 19218188
  18. TDO mediates antimicrobial and immunoregulatory effects. TDO-dependent inhibition of T-cell growth might be involved in the immunotolerance observed in vivo during allogeneic liver transplantation. PMID: 19637229
