Disease

NCF1_HUMAN Defects in NCF1 are the cause of chronic granulomatous disease autosomal recessive cytochrome-b-positive type 1 (CGD1) [MIM:233700. Chronic granulomatous disease is a genetically heterogeneous disorder characterized by the inability of neutrophils and phagocytes to kill microbes that they have ingested. Patients suffer from life-threatening bacterial/fungal infections.^[1] ^[2]

Function

NCF1_HUMAN NCF2, NCF1, and a membrane bound cytochrome b558 are required for activation of the latent NADPH oxidase (necessary for superoxide production).^[3]

Publication Abstract from PubMed

The multi-subunit NADPH oxidase complex plays a crucial role in host defense against microbial infection through the production of reactive oxygen species. Activation of the NADPH oxidase requires the targeting of a cytoplasmic p40-p47-p67(phox) complex to the membrane bound heterodimeric p22-gp91(phox) flavocytochrome. This interaction is prevented in the resting state due to an auto-inhibited conformation of p47(phox). The X-ray structure of the auto-inhibited form of p47(phox) reveals that tandem SH3 domains function together to maintain the cytoplasmic complex in an inactive form. Further structural and biochemical data show that phosphorylation of p47(phox) activates a molecular switch that relieves the inhibitory intramolecular interaction. This permits p47(phox) to interact with the cytoplasmic tail of p22(phox) and initiate formation of the active, membrane bound enzyme complex.
