| Tissue Specificity | Detected in neutrophils (at protein level). |
| Post Translational Modifications | Glycosylated. Phosphorylated on Ser and Thr residues by PKC during neutrophils activation. Phosphorylation enhances the NADPH oxidase activity and stimulates its interaction with RAC2, NCF2/p67-phox, and NCF1/p47-phox. Undergoes 'Lys-48'-linked polyubiquitination, likely by RNF145, triggering endoplasmic reticulum-associated degradation. |
| Function | Catalytic subunit of the phagocyte NADPH oxidase complex that mediates the transfer of electrons from cytosolic NADPH to O2 to produce the superoxide anion (O2(-)). In the activated complex, electrons are first transferred from NADPH to flavin adenine dinucleotide (FAD) and subsequently transferred via two heme molecules to molecular oxygen, producing superoxide through an outer-sphere reaction (Probable). Activation of the NADPH oxidase complex is initiated by the assembly of cytosolic subunits of the NADPH oxidase complex with the core NADPH oxidase complex to form a complex at the plasma membrane or phagosomal membrane. This activation process is initiated by phosphorylation dependent binding of the cytosolic NCF1/p47-phox subunit to the C-terminus of CYBA/p22-phox. NADPH oxidase complex assembly is impaired through interaction with NRROS. |
