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]

About this Structure

1w70 is a 4 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
