Indoleamine 2,3-dioxygenase 2 (IDO2) is a protein that in humans is encoded by the IDO2 gene .[ 5]
IDO2 (indolamine-2,3-dioxygenase) is an enzyme with protein size of 420 amino acids (47 kDa) that is used for catabolism of tryptophan . In organisms, other enzymes participate in L -tryptophan cleavage, namely IDO1 and TDO . Despite IDO1 and IDO2 being closely related enzymes originating by gene duplication and sharing high level (43%) of sequence homology,[ 6] [ 7] [ 8] [ 9] [ 10] Treg differentiation in vitro ,[ 11] [ 12]
