Neutrophil cytosolic factor 4
Neutrophil cytosol factor 4 is a protein that in humans is encoded by the NCF4 gene.[5][6]
Function
[edit]The protein encoded by this gene is a cytosolic regulatory component of the superoxide-producing phagocyte NADPH-oxidase, a multicomponent enzyme system important for host defense. This protein is preferentially expressed in cells of myeloid lineage. It interacts primarily with neutrophil cytosolic factor 2 (NCF2/p67-phox) to form a complex with neutrophil cytosolic factor 1 (NCF1/p47-phox), which further interacts with the small G protein RAC1 and translocates to the membrane upon cell stimulation. This complex then activates flavocytochrome b, the membrane-integrated catalytic core of the enzyme system. The PX domain of this protein can bind phospholipid products of the PI(3) kinase, which suggests its role in PI(3) kinase-mediated signaling events. The phosphorylation of this protein was found to negatively regulate the enzyme activity. Alternatively spliced transcript variants encoding distinct isoforms have been observed.
Clinical significance
[edit]GWAS studies showed that Crohn's disease patient with certain SNPs in NCF4 are more susceptible to get Crohn's disease.[7] Crohn's patient with rs4821544 variants showed a decreased reactive oxygen species after stimulation with GM-CSF which is a proinflammtory cytokine.[8]
Interactions
[edit]Neutrophil cytosolic factor 4 has been shown to interact with Ku70,[9] Neutrophil cytosolic factor 1[10][11][12] and Moesin.[13]
