IDO Gene Sequence, Family, Fuction and Expression Information

IDO cDNA / Gene Overview

IDO1 gene / cDNA is a protein-coding gene which located on 8p11.21. The IDO1 gene is conserved in chimpanzee, Rhesus monkey, dog, cow, mouse, rat, S.cerevisiae, E.gossypii, M.oryzae, and N.crassa.114 organisms have orthologs with human gene IDO1.

IDO cDNA / Gene Function

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.[provided by RefSeq, Feb 2011]
