IDO2(indoleamine 2,3-dioxygenase 2),癌症关联基因,基因ID:169355,与由indo(mim 147435)和tdo2(mim 191070)基因编码的酶一起,indol1基因编码的酶在kynurenine途径中代谢色氨酸(ball等人,2007年[pubmed 17499941])。[由omim提供,2011年2月]Along with the enzymes encoded by the INDO (MIM 147435) and TDO2 (MIM 191070) genes, the enzyme encoded by the INDOL1 gene metabolizes tryptophan in the kynurenine pathway (Ball et al., 2007 [PubMed 17499941]).[supplied by OMIM, Feb 2011]。
