IDO-2 Protein, Human (His)

The IDO-2 protein plays a key role in cellular processes, catalyzing the initial and rate-limiting steps in the catabolism of the essential amino acid tryptophan in the kynurenine pathway. This enzymatic activity has been confirmed in multiple studies, establishing IDO-2 as a key regulator of tryptophan metabolism with important implications for immune regulation. IDO-2 Protein, Human (His) is the recombinant human-derived IDO-2 protein, expressed by E. coli , with C-6*His labeled tag.

Indoleamine 2,3-dioxygenase 2 (IDO-2) is an enzyme that catalyzes the first and rate-limiting step in the catabolism of the essential amino acid tryptophan along the kynurenine pathway. This pathway is crucial for the regulation of tryptophan metabolism and has implications in immune regulation. IDO-2's activity contributes to immune modulation by limiting tryptophan availability, which, in turn, affects immune cell function. While IDO-2 is involved in immune regulation, it may not play a significant role in tryptophan-related tumoral resistance, as suggested by certain studies.
