| 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. |
| Post Translational Modifications | Isoform 4: N-glycosylated and glycosylation is required for its proper function. Isoform 3: N-glycosylated. |
| Function | NADPH oxidase that catalyzes predominantly the reduction of oxygen to H2O2. Can also catalyze to a smaller extent, the reduction of oxygen to superoxide. 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 4: NADPH oxidase that catalyzes the generation of superoxide from molecular oxygen utilizing NADPH as an electron donor. Involved in redox signaling in vascular cells. Modulates the nuclear activation of ERK1/2 and the ELK1 transcription factor, and is capable of inducing nuclear DNA damage. Isoform 3: Lacks superoxide-generating NADPH oxidase activity. |
