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.
Molecular Function: protein binding; electron carrier activity; superoxide-generating NADPH oxidase activity; phosphatidylinositol-3,4-bisphosphate binding; SH3 domain binding; phosphoinositide binding
Biological Process: respiratory burst during defense response; respiratory burst; interaction with host; apoptosis; superoxide metabolic process; antigen processing and presentation of exogenous peptide antigen via MHC class I, TAP-dependent; leukotriene metabolic process; cell proliferation; antigen processing and presentation of peptide antigen via MHC class I; negative regulation of smooth muscle contraction; cellular defense response; antigen processing and presentation of exogenous peptide antigen via MHC class I; innate immune response; response to yeast; protein targeting to membrane; inflammatory response; vascular endothelial growth factor receptor signaling pathway; superoxide release; hydrogen peroxide biosynthetic process
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
