The protein encoded by NCF4 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 neutrophil cytosolic factor 4 was found to negatively regulate the enzyme activity. Alternatively spliced transcript variants encoding distinct isoforms have been observed.

Phospho-p40-phox (T154) Polyclonal Antibody detects endogenous levels of p40-phox protein only when phosphorylated at T154.

Optimal working dilutions should be determined experimentally by the investigator. Suggested starting dilutions are as follows: IHC-p: 1:100-1:300, ELISA: 1:5000. Not yet tested in other applications.
