一般說明
NQO1(NAD(P)H醌脱氢酶1)是一种专性双电子还原酶。它是一种细胞质同型二聚体蛋白,每个单体有一个FAD分子。该基因位于人染色体16q23上。它在组织中广泛表达。
生化/生理作用
NQO1(NAD(P)H醌脱氢酶1)以NADH或NADPH为还原辅因子,具有双香豆素抑制作用。人们认为它可以抵抗天然和外源性醌的作用。它参与将苯衍生的醌转化为毒性较小的对苯二酚,还参与苯相关的血液毒性作用。它参与了一些化疗药物和环境致癌物的还原和最终激活,如杂环胺、硝基芳香化合物和可能的香烟烟雾微粒。该基因的C609T空变异与北印度患者的乳腺癌易感性有关。NQO1在浆液性卵巢癌中表达上调,这种表达与预后不良有关,因此该基因有可能作为其生物标志物。
