Protein-protein Interaction (2)

Gene RIF (16)

25066423 Crystal tryptophan 2,3-dioxygenase structure revealed eight residues playing critical roles in L-tryptophan oxidation.
24974860 IL-1beta is suggested to stimulate tryptophan catabolism and production of IL-6 and IL-8 by increasing TDO expression in endometriosis.
23630570 TDO is highly expressed in the brains of Alzheimer disease patients.
23558111 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.
22082147 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.
21892828 The data suggest that TDO uses a ring-opening mechanism during N-formylkynurenine formation, rather than Criegee or dioxetane mechanisms as previously proposed.
21361337 Studies indicate that the heme dioxygenases are differentiated by their ability to catalyze the oxidation of l-tryptophan to N-formylkynurenine.
20361220 subtle differences between the TDO and IDO reactions
19637229 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.
19502010 Observational study of gene-disease association and gene-gene interaction. (HuGE Navigator)
19218188 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.
18370401 significant mechanistic differences exist across the heme dioxygenase family, and the data are discussed within this broader framework
15390107 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.
14755447 Polymorphism of tryptophan 2,3 dioxygenase gene is associated with autism.
12634647 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.
