A Fluorescently Tagged C-Terminal Fragment of p47phox Detects NADPH Oxidase Dynamics during Phagocytosis
NADPH Oxidase Dynamics phagocytosis
2014/12/12
The assembly of cytosolic p47phox and p67phox with flavocytochrome b558 at the membrane is crucial for activating the leukocyte NADPH oxidase that generates superoxide for microbial killing. p47phox a...
FcγR-stimulated activation of the NADPH oxidase: phosphoinositide-binding protein p40phox regulates NADPH oxidase activity after enzyme assembly on the phagosome
NADPH oxidase p40phox
2014/12/12
The phagocyte NADPH oxidase generates superoxide for microbial killing, and includes a membrane-bound flavocytochrome b558 and cytosolic p67phox, p47phox, and p40phox subunits that undergo membrane tr...
Rac Activation Induces NADPH Oxidase Activity in Transgenic COSphox Cells and Level of Superoxide Production is Exchange Factor-Dependent
NADPH oxidase Rac

Transient expression of constitutively active Rac1 derivatives, (G12V) or (Q61L), was sufficient to induce phagocyte NADPH oxidase activity in a COS-7 cell model in which human cDNAs for essential oxi...
Rac GTPase isoform-specific regulation of NADPH oxidase and chemotaxis in murine neutrophils in vivo: Role of the C-terminal polybasic domain
Rac GTPase NADPH oxidase
2014/12/12
The Rho family GTPase Rac acts as a molecular switch for signal transduction to regulate various cellular functions. Mice deficient in the hematopoietic-specific Rac2 isoform exhibit agonist-specific ...
The phosphoinositide-binding protein p40phox activates the NADPH oxidase during FcγIIA receptor–induced phagocytosis
NADPH oxidase phagocytosis
2014/12/12
Superoxide produced by the phagocyte reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase is essential for host defense. Enzyme activation requires translocation of p67phox, p47phox, an...
