IDO1

indoleamine 2,3-dioxygenase 1

This gene encodes indoleamine 2,3-dioxygenase (IDO) - a heme enzyme that catalyzes the first and rate-limiting step in tryptophan catabolism to N-formyl-kynurenine. This enzyme acts on multiple tryptophan substrates including D-tryptophan, L-tryptophan, 5-hydroxy-tryptophan, tryptamine, and serotonin. This enzyme is thought to play a role in a variety of pathophysiological processes such as antimicrobial and antitumor defense, neuropathology, immunoregulation, and antioxidant activity. Through its expression in dendritic cells, monocytes, and macrophages this enzyme modulates T-cell behavior by its peri-cellular catabolization of the essential amino acid tryptophan.

AD Risk Scores

About AD Risk Scores

The TREAT-AD Center at Emory-Sage-SGC has developed a Target Risk Score (TRS) to objectively rank the potential involvement of specific genes in AD. The TRS is derived by summing two component risk scores, the Genetic Risk Score and the Multi-omic Risk Score, each of which is derived from a meta-analysis of multiple harmonized data sets. More information about the methodology used to define these risk scores is available here.

AD Risk Scores for IDO1

The TRS for IDO1, along with the component Genetic and Multi-omic Risk Scores, is shown here. The scores for IDO1 are superimposed on the genome-wide score distributions. If No Data is Currently Available is displayed for a score, that score was not calculated for IDO1.

Biological Domain Classification

About Biological Domains

A biological domain represents a standardized area of biology defined by a set of discrete, biologically coherent GO terms. The TREAT-AD Center at Emory-Sage-SGC has defined nineteen biological domains associated with AD, and objectively mapped genes to those biological domains using GO term annotations. More information about the methodology used to define AD biological domains, and to generate genome-wide biological domain mappings, is available here.

Biological Domains for IDO1

Select a biological domain on the left to see the list of GO terms that link IDO1 to it on the right. The percentage value displayed next to the currently selected biological domain indicates the proportion of IDO1's total unique GO terms that map to the biological domain. The ratio displayed on the right indicates how many of the biological domain's total GO terms IDO1 is annotated with.
