该基因是NAD(P)H脱氢酶(醌)家族的成员,编码胞质2-电子还原酶。这种FAD结合蛋白形成同二聚体,并将醌类还原为对苯二酚类。这种蛋白质的酶活性阻止了醌类的单电子还原,从而导致自由基的产生。该基因突变与迟发性运动障碍(TD)、暴露于苯后血液毒性风险增加以及对各种癌症的易感性有关。这种蛋白的改变表达在许多肿瘤中都有发现,也与阿尔茨海默病(AD)有关。编码不同亚型的替代转录剪接变异体已经被描述。
This gene is a member of the NAD(P)H dehydrogenase (quinone) family and encodes a cytoplasmic 2-electron reductase. This FAD-binding protein forms homodimers and reduces quinones to hydroquinones. This protein's enzymatic activity prevents the one electron reduction of quinones that results in the production of radical species. Mutations in this gene have been associated with tardive dyskinesia (TD), an increased risk of hematotoxicity after exposure to benzene, and susceptibility to various forms of cancer. Altered expression of this protein has been seen in many tumors and is also associated with Alzheimer's disease (AD). Alternate transcriptional splice variants, encoding different isoforms, have been characterized.
