Tissue distribution and putative physiological function of NOX family NADPH oxidases

Published in Japanese journal of infectious diseases. 2004, vol. 57, no. 5, p. S28-29
Abstract The NOX family of ROS-generating NADPH oxidases consists of 7 members: NOX1 to NOX5, DUOX1 and 2. NOX1 is predominantly found in the colon, where it possibly plays a role in the host defense. NOX2 is the phagocyte NADPH oxidase, a clearly established host defense enzyme. NOX3 is almost exclusively expressed in the inner ear, where it is involved in otoconia morphogenesis, but based on its localization might also play a role in the auditory system. NOX4, widely expressed in kidney, vascular cells, osteoclasts etc.; it might be a constitutively active enzyme, regulated on the level of gene expression but its precise physiological function remains unknown. NOX5, a Ca2+ activated enzyme is predominantly expressed in lymphoid tissues and testis, where it might be involved in signaling processes. DUOX1 is expressed in the thyroid and in respiratory epithelia, and DUOX2 in the thyroid and in gastrointestinal glandular epithelia. Both DUOX enzymes are involved in thyroid hormone synthesis, but possibly also in epithelial host defense.
