Dual oxidase 1 also known as DUOX1 or ThOX1 (for thyroid oxidase) is an enzyme which in humans is encoded by the DUOX1 gene. DUOX1 was first identified in the mammalian thyroid gland. In humans two isoforms are found; hDUOX1 and hDUOX2. Human DUOX protein localization is not exclusive to thyroid tissue; hDUOX1 is prominent in airway epithelial cells and hDUOX2 in the salivary glands and gastrointestinal tract.
