Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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.2 Publications

Enzyme regulationi

Activated by insulin. Inhibited by diphenylene iodonium (By similarity). Inhibited by plumbagin. Activated by phorbol 12-myristate 13-acetate (PMA).By similarity2 Publications
