NOX2 Antibody/ gp91phox / CYBB, 100 ug

NADPH Oxidase 2, also called CYBB, p91-PHOX or GP91-1, is an essential component of phagocytic NADPH-oxidase, a membrane-bound enzyme complex that generates large quantities of microbicidal superoxide and other oxidants upon activation. NOX2 assembled on DC phagosomes in a gp91-phox subunit-dependent manner, and reactive oxygen species were produced in a more sustained manner in immature DC phagosomes than in macrophage phagosomes. As a major player in innate immune responses in neutrophils, it is also involved in adaptive immunity through its activity in DCs. In heart cells, physiologic stretch rapidly activates reduced-form NOX2 to produce reactive oxygen species (ROS) in a process dependent on microtubules (X-ROS signaling).
