Regulation of the human neutrophil NADPH oxidase by rho-related G-proteins.


Superoxide production by phagocytic white blood cells requires the assembly of an NADPH oxidase from membrane and cytosolic proteins. Recombinant cytosolic proteins p47phox and p67phox and neutrophil membranes were used to purify a third cytosolic component that is necessary and sufficient for cell-free reconstitution of NADPH oxidase. The component was… (More)
