Constitutive NADPH oxidase which generates superoxide intracellularly upon formation of a complex with CYBA,p22phox. Regulates signaling cascades probably through phosphatases inhibition. May function as an oxygen sensor regulating the KCNK3,TASK-1 potassium channel and HIF1A activity. May regulate insulin signaling cascade. May play a role in apoptosis, bone resorption and lipolysaccharide-mediated activation of NFKB.
Direct interaction of the novel Nox proteins with p22phox is required for the formation of a functionally active NADPH oxidase.Ambasta R.K., Kumar P., Griendling K.K., Schmidt H.H.H.W., Busse R., Brandes R.P.J. Biol. Chem. 279:45935-45941(2004)
