NQO-1 (NADPH Quinone acceptor Oxidoreductase 1; also DTD and Menadione reductase) is a 31-33 kDa cytoplasmic member of the NAD(P)H dehydrogenase family of enzymes. It is widely expressed, being found in adipocytes, endothelial cells and hepatocytes. NQO-1 serves as a cytoprotective molecule, reducing quinones (atmospheric benzene and esrtrogen compounds) and nitroaromatics without consuming sulfhydryl compounds. It also acts as a backup superoxide scavenger to SOD. NQO-1 reportedly binds and stabilizes key cell protection molecules such as p53, thus acting as a gatekeeper for proteosome-mediated protein turnover. Human NQO-1 is 274 amino acids (aa) in length. It contains an FMN reductase domain (aa 5-212) and two utilized Lys acetylation sites. NQO-1 functions as a noncovalent homodimer. There are three potential at Met22, while two others show a deletion of aa 141-174 and 102-139, respectively. Full length human NQO-1 shares 86% aa sequence identity with mouse NQO-1.

Scientific Data Images for Human NQO-1 Antibody
Detection of Human NQO-1 by Western Blot.
Western blot shows lysates of MCF-7 human breast cancer cell line, HeLa human cervical epithelial carcinoma cell line, human lung tissue, and human kidney tissue. PVDF membrane was probed with 0.25 µg/mL of Sheep Anti-Human NQO-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7567) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for NQO-1 at approximately 30 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.Applications for Human NQO-1 Antibody
