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]       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Interactions[edit]Neutrophil cytosolic factor 4 has been shown to interact with Ku70,[9]Neutrophil cytosolic factor 1[10][11][12] and Moesin.[13]References[edit]^ a b c ENSG00000100365 GRCh38: Ensembl release 89: ENSG00000275990, ENSG00000100365 – Ensembl, May 2017^ a b c GRCm38: Ensembl release 89: ENSMUSG00000071715 – Ensembl, May 2017^ “Human PubMed Reference:”.
