p47phox NCF2, NCF1, and a membrane bound cytochrome b558 are required for activation of the latent NADPH oxidase (necessary for superoxide production). Detected in peripheral blood monocytes and neutrophils (at protein level). 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
