[HTML][HTML] Arachidonic acid induces direct interaction of the p67phox-Rac complex with the phagocyte oxidase Nox2, leading to superoxide production

The phagocyte NADPH oxidase Nox2, heterodimerized with p22 phox in the membrane, is
dormant in resting cells but becomes activated upon cell stimulation to produce superoxide,
a precursor of microbicidal oxidants. Nox2 activation requires two switches to be turned on
simultaneously: a conformational change of the cytosolic protein p47 phox and GDP/GTP
exchange on the small GTPase Rac. These proteins, in an active form, bind to their
respective targets, p22 phox and p67 phox, leading to productive oxidase assembly at the …
