|
Function |
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. May produce superoxide in the nucleus and play a role in regulating gene expression upon cell stimulation. Isoform 3 is not functional. Isoform 5 and isoform 6 display reduced activity.

Subcellular Location |
Endoplasmic reticulum membrane; Multi-pass membrane protein. Cell membrane {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}. Cell junction, focal adhesion {ECO:0000305}. Note=May localize to plasma membrane and focal adhesions. According to PubMed:15927447, may also localize to the nucleus.

Tissue Specificity |
Expressed by distal tubular cells in kidney cortex and in endothelial cells (at protein level). Widely expressed. Strongly expressed in kidney and to a lower extent in heart, adipocytes, hepatoma, endothelial cells, skeletal muscle, brain, several brain tumor cell lines and airway epithelial cells. {ECO:0000269|PubMed:11032835, ECO:0000269|PubMed:11376945, ECO:0000269|PubMed:15210697, ECO:0000269|PubMed:16324151}.
