Catalyzes the first and rate limiting step of the catabolism of the essential amino acid tryptophan along the kynurenine pathway. Involved in immune regulation. May not play a significant role in tryptophan-related tumoral resistance.

Multiple-scattering (MS) analysis of EXAFS data on met-indoleamine 2,3-dioxygenase-2 (IDO2) and analysis of XANES have provided the first direct structural information about the axial donor ligands of the iron center for this recently discovered protein. PMID: 24858687
IDO2 is expressed in both mDCs and plasmacytoid DCs and is not modulated by PGE2. IDO2 expression is constitutively, stably expressed in steady-state conditions and may contribute to the homeostatic tolerogenic capacity of DCs. PMID: 24391212
Indoleamine2,3-dioxygenase and tryptophanyl-tRNA synthetase may play critical roles in the immune pathogenesis of chronic kidney disease. PMID: 23651343

Data show that IDO2-specific T cells are cytotoxic effector cells that recognize and kill tumor cells. PMID: 21406395
Tryptophan supplementation was able to completely restore hepatitis b virus replication in IFN-gamma- but not IFN-alpha-treated cells, which strongly argues that IDO is the primary mediator of IFN-gamma-elicited antiviral response in human hepatocytes. PMID: 21084489
High activity of indoleamine 2,3 dioxygenase enzyme predicts disease severity and case fatality in bacteremic patients. PMID: 19487973
The pro-apoptotic activity of indoleamine 2, 3-dioxygenase is responsible for its transcriptional regulation and the modulation of its pro-apoptotic activity during death receptor activation in melanoma cells. PMID: 19799997
First study to report IDO2 expression in pancreatic ductal adenocarcinoma indicating that IDO2 genetic polymorphisms do not negate interferon-gamma-inducible protein expression. PMID: 19476837
IDO2 encodes a novel IDO-related tryptophan catabolic enzyme that is preferentially inhibited by D-1-methyl-tryptophan (D-1MT). IDO2 may have a distinct role in immune tolerance. Two common human genetic polymorphisms ablate IDO2 enzyme activity. PMID: 17671174
This article describes the evolutionary relationships between the INDO and INDOL1 genes. The INDOL1 protein has a distinct expression pattern compared to INDO and both have the ability to catabolise tryptophan. PMID: 17499941
