a component of the NADPH-oxidase, a multicomponent enzyme system responsible for the oxidative burst. Upon neutrophil stimulation, this protein and other cytosolic elements are sent to the cell membrane from the cytosol to form a complex which produces phagocytic oxygen radicals. Responsible for the downregulation of NADPH-oxidase. Alternative splicing has been observed. Note: This description may include information from UniProtKB.
Molecular Function: protein dimerization activity; protein binding; superoxide-generating NADPH oxidase activator activity; phosphatidylinositol 3-phosphate binding
Biological Process: positive regulation of catalytic activity; interaction with host; antigen processing and presentation of peptide antigen via MHC class I; 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; immune response
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.
