    basic FUNCTION
  • p67-phox, oxygen dependent mechanism of phagocytosis
  • reduction of oxygen to O-2 at the expense of NADPH, the O2-generated is the precursor of potent oxidants used to kill the invading microorganisms
  • being a membrane bound cytochrome b558 required for activation of the latent NADPH oxidase
  • essential component of the multi-protein NADPH oxidase enzyme in phagocytic leukocytes, as well as in certain non-phagocytic cells
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS inflammation , electron transport
    PATHWAY
    metabolism other
    signaling
    superoxide metabolism
    a component
  • component of NADPH oxidase system cypb245
  • forming a cytosolic precomplex with NCF1 and NCF4
  • component of an intracellular complex made of CYBB, CYBA, NCF2, NCF4 in unstimulated endothelial cells
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting directly with cytochrome b58 (CYBB)
  • SYTL1
  • RAC1
  • interacting with PLAGL2
  • NCF2 binding to VAV1 involves their respective PB1 and ZF domains
    • cell & other
    REGULATION
    activated by binding to CYBB activated by RAC1
    Other regulated through mechanisms that include modulation of transcription and translation
    regulated by PLAGL2, but overexpression of PLAGL2 alone was not sufficient to activate an NCF2 promoter-reporter plasmid, suggesting the requirement for other factors

    Susceptibility to systemic lupus erythematosus (SLE)
    Variant & Polymorphism SNP
  • a single nonsynonymous coding mutation in exon 12, the effect of which is the substitution of histidine-389 with glutamine (H389Q) in the PB1 domain of the NCF2 protein, associated with SLE
