Nox4 Antibody [FITC]

NOX4 (NADPH oxidase 4) is a constitutive NADPH oxidase which complex with CYBA/p22phox for generating superoxide intracellularly and is found primarily in vascular cells, fibroblasts, osteoclasts and is abundantly expressed in the kidney. NOX4 regulates signaling cascades through phosphatases inhibition and function as oxygen sensor regulating the KCNK3/TASK-1 potassium channel as well as HIF1 alpha activity. NOX4 has also been implicated in regulation of insulin signaling cascade, apoptosis, bone resorption and LPS-mediated activation of NFkB. In vascular smooth muscle cells, NOX4 is positively regulated by Poldip2 which is a Nox4/p22phox interacting protein and Nox4/p22phox-Poldip2 complex regulates Rho-dependent cytoskeletal reorganization as well as cellular migration. TGF- beta is another positive regulator of Nox4 which is important in vascular fibrosis and differentiation. Unlike Nox1/Nox2, Nox4 is constitutively active, producing primarily H2O2 rather thanO2 and this difference in the species generated underlie NOX-specific actions in cell signaling. Nox4 contributes to basal ROS production through its constitutive activity and to increased ROS generation when stimulated by Ang II, glucose, TNF alpha and growth factors. NOX4 has been implicated in hypertension, atherosclerosis, and cardiovascular and renal complications of diabetes and in remodeling of pulmonary arteries in hypertension.
