Anti-NOX4 Antibody, clone 10A8.1

NADPH oxidase 4 (UniProt Q9NPH5; also known as Kidney oxidase-1, Kidney superoxide-producing NADPH oxidase, KOX-1, Renal NAD(P)H-oxidase) is encoded by the NOX4 (also known as RENOX) gene (Gene ID 50507) in human. NOX4 belongs to the family of NADPH oxidases that modulate redox-dependent cellular signalling pathways via intracellular reactive oxygen species (ROS) generation. Seven family members have been identified in mammals (NOX1–5 and DUOX1/2) with member-specific cellular distribution, intracellular location, mechanisms of action and types of ROS produced. NOX4 produces predominantly H2O2, and is widely expressed in many cell types and adult tissues, including kidney, liver, heart and aorta. NOX4 plays an important role in homocysteine (Hcy) metabolism, which in turns is a determining factor that impacts on defence against environmental toxins. Nox-knocout in mice results in significantly decreased total plasma Hcy levels, causing markedly increased susceptibility to acetaminophen- (APAP-, paracetamol-) induced hepatoxicity as a result of significantly decreased cysteine production and hepatic GSH stores. Human NOX4 is a six-transmembrane (a.a. 17-37, 63-83, 104-124, 155-175, 189-209, 425-445) protein, having both its N- and C-terminal ends at the cytoplasmic side (a.a. 1-16 & 446-578).
