the 47-kilodalton cytosolic subunit of the multi-protein complex known as NADPH oxidase found in neutrophils. The holo-oxidase produces a burst of superoxide which is delivered to the lumen of the neutrophil phagosome. Contains 2 SH2 domains. Mutations in NCF1, as well as in other NADPH oxidase subunits, can result in chronic granulomatous disease. Note: This description may include information from UniProtKB.
Cellular Component: cytosol; extrinsic to membrane; NADPH oxidase complex
Molecular Function: electron carrier activity; phosphatidylinositol-3,4-bisphosphate binding; phosphoinositide binding; protein binding; SH3 domain binding; superoxide-generating NADPH oxidase activity
Biological Process: antigen processing and presentation of exogenous peptide antigen via MHC class I; antigen processing and presentation of exogenous peptide antigen via MHC class I, TAP-dependent; antigen processing and presentation of peptide antigen via MHC class I; cell proliferation; cell redox homeostasis; cellular defense response; hydrogen peroxide biosynthetic process; inflammatory response; innate immune response; leukotriene metabolic process; negative regulation of smooth muscle contraction; protein targeting to membrane; respiratory burst; respiratory burst during defense response; response to yeast; small GTPase mediated signal transduction; superoxide metabolic process; superoxide release; vascular endothelial growth factor receptor signaling pathway
