简介：这个基因，cyp2b6，编码细胞色素p450酶超家族的一个成员。细胞色素p450蛋白是一种单加氧酶，催化药物代谢和胆固醇、类固醇等脂类的合成。该蛋白定位于内质网，由苯巴比妥诱导表达。已知这种酶能代谢一些外源性物质，如抗癌药物环磷酰胺和ifosphamide。该基因的转录变体已经被描述过；然而，这些转录物究竟是由该基因产生的，还是由一个密切相关的假基因cyp2b7产生的，还没有得到解决。该基因和假基因均位于染色体19q上cyp2a、cyp2b和cyp2f亚家族的一大簇细胞色素p450基因中的cyp2a假基因的中间。This gene, CYP2B6, encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum and its expression is induced by phenobarbital. The enzyme is known to metabolize some xenobiotics, such as the anti-cancer drugs cyclophosphamide and ifosphamide. Transcript variants for this gene have been described; however, it has not been resolved whether these transcripts are in fact produced by this gene or by a closely related pseudogene, CYP2B7. Both the gene and the pseudogene are located in the middle of a CYP2A pseudogene found in a large cluster of cytochrome P450 genes from the CYP2A, CYP2B and CYP2F subfamilies on chromosome 19q.
