This entry includes dual oxidase 1 (DUOX1) from mammals and Duox from fruit flies. DUOX1 and DUOX2 are isoenzymes that belong to the family of NADPH oxidases (Nox) []. They function as calcium-dependent NADPH oxidases producing hydrogen peroxide (H2O2) necessary for thyroid hormone biosynthesis []. Duox is found indispensable for gut antimicrobial activities in fruit flies [].
This entry represents dual oxidase 2 (DUOX2). DUOX1 and DUOX2 are isoenzymes that belong to the family of NADPH oxidases (Nox) []. They function as calcium-dependent NADPH oxidases producing hydrogen peroxide (H2O2) which is required for thyroid hormone biosynthesis []and the activity of lactoperoxidase (LPO) []. Duox2 is activated by activation of protein kinase C (PKC) and can be suppressed by thyroglobulin (Tg) [, ].
