Anti-IDO-2 Antibody, clone 4-3

Indoleamine 2,3-dioxygenase 2 (UniProt: Q8R0V5; also known as IDO-2, Indoleamine 2,3-dioxygenase-like protein 1, Indoleamine-pyrrole 2,3-dioxygenase-like protein 1) is encoded by the Ido2 (also known as Indol1) gene (Gene ID: 209176) in murine species. IDO-2 is expressed mainly in antigen-presenting immune cells, liver, kidney, brain, and placenta. It is highly expressed in kidney, followed by epididymis and liver and is also detected in the tails of the spermatozoa. It catalyzes the first and rate-limiting step in the kynurenine pathway of tryptophan catabolism. IDO-1 and IDO-2 are 2 distinct enzymes which catalyze the same reaction. However, the Km for IDO-2 for tryptophan is much higher than that of IDO-1. IDO-2 may play a role as a negative regulator of IDO-1 by competing for heme-binding with IDO-1. IDO-2 activity is inhibited by 1MT (1-methyl-tryptophan) and MTH-trp (methylthiohydantoin-DL-tryptophan). IDO-2 is also involved in immune regulation. IDO-2 knockout mice do not show any apparent defects in their embryonic development or hematopoietic differentiation and have wild-type profiles for kynurenine in blood serum and for immune cells in spleen, lymph nodes, peritoneum, thymus and bone marrow. However, the knockout mice exhibit defects in IDO-mediated T-cell regulation and inflammatory responses. (Ref.: Mbongue JC, et al. (2015). Vaccines (Basel). 3(3):703-29).
