| Tissue Specificity | Detected in neutrophils (at protein level). |
| Post Translational Modifications | Glycosylated. Phosphorylated on Ser and Thr residues. Undergoes 'Lys-48'-linked polyubiquitination, likely by RNF145, triggering endoplasmic reticulum-associated degradation. |
| Function | Critical component of the membrane-bound oxidase of phagocytes that generates superoxide. It is the terminal component of a respiratory chain that transfers single electrons from cytoplasmic NADPH across the plasma membrane to molecular oxygen on the exterior. Also functions as a voltage-gated proton channel that mediates the H(+) currents of resting phagocytes. It participates in the regulation of cellular pH and is blocked by zinc. |
