Anti-NOX4 antibody produced in rabbit

NOX4 (NADPH oxidase 4) belongs to the NOX family of proteins, and is the major member of this family to be expressed in human brain pericytes. It is also highly expressed in kidney, endothelial and vascular smooth muscle cells. It resides in mitochondrial membrane and endoplasmic reticulum (ER). It is a transmembrane protein, which contains two heme groups, and its C-terminal contains flavin adenine dinucleotide and NADPH-binding domains.

Anti-NOX4 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

NOX4 (NADPH oxidase 4) is involved in the growth and proliferation of human brain pericytes. It is activated by hypoxia and angiotensin II, and is responsible for the production of reactive oxygen species (ROS) in brain pericyte membranes, in an NAD(P)H-dependent manner. It might be one of the factors involved in the pathogenesis of cardiovascular disorders. It is involved in pathogen elimination, where NOX-4-produced ROS, by phagocytes, facilitates autophagy. This also determines the survival of vascular and tumor cells. In hypoxic conditions, this protein facilitates erythropoietin secretion in kidney. It has cardioprotective role during energy crisis, and this is achieved by the activation of Nox4/PERK/eIF-2α/ATF4 signaling cascade. NOX4-produced ROS also regulates the activation of redox-sensitive pathways, which in turn determines the replication of Influenza virus in the epithelial cells of lungs.

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
