NCF1 Proteins and Enzymes

NCF1, along with NCF2 and a membrane bound cytochrome b558, is required for activation of the latent NADPH oxidase necessary for superoxide production. Defects in NCF1 are the cause of autosomal cytochrome-b-positive chronic granulomatous disease type 1 (CGD). NCF1 is a cytosolic subunit of the multi-protein complex known as NADPH oxidase found in neutrophils.
