1/1000. Predicted molecular weight: 41 kDa.
FunctionConstitutively potentiates the superoxide-generating activity of NOX1 and NOX3 and is required for the biogenesis of otoconia/otolith, which are crystalline structures of the inner ear involved in the perception of gravity. Isoform 3 is more potent than isoform 1 in activating NOX3. Together with NOXA1, may also substitute to NCF1/p47phox and NCF2/p67phox in supporting the phagocyte NOX2/gp91phox superoxide-generating activity.
Tissue specificityExpressed in testis, small and large intestines, liver, kidney and pancreas. Isoform 3 is mainly expressed in colon. Isoform 1 is preferentially expressed in testis.
Developmental stageIsoform 3 is expressed in fetal liver.
DomainThe PX domain mediates lipid-binding, localization to the plasma membrane and is required for NOX1 activation. The SH3 domains mediate interaction with CYBA/p22phox. Also mediates intramolecular interaction with the proline-rich region.
Cellular localizationCell membrane. Isoform 3 associates with the plasma membrane in a lipid-dependent manner.
