Description

Neutrophil cytosol factor 2 (UniProt Q09014, also known as 67 kDa neutrophil oxidase factor, NADPH oxidase activator 2, NADPH oxidase subunit 67 kDa, NCF-2, Ncf2, Neutrophil NADPH oxidase factor 2, p67-phox, p47phox) is encoded by the murine Ncf2 (also known as Noxa2, p67phox) gene in murine species (Gene ID 17970). Activation of NADPH-oxidase dependent superoxide generation requires the participation of several cytosolic factors, including p47-phox, p67-phox, p40-phox and Rac. In the resting cell p47phox, p67phox, and p40phox form a large molecular weight cytosolic complex. Activation of the NADPH oxidase is initiated by the assembly of p47phox, p67phox, and Rac with cytochrome b558 in a 1:1:1:1 complex in the plasma membrane.
