This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases that 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 glucocorticoids and some pharmacological agents. This enzyme is involved in the metabolism of approximately half the drugs in use today, including acetaminophen, codeine, cyclosporin A, diazepam and erythromycin. The enzyme also metabolizes some steroids and carcinogens. This gene is part of a cluster of cytochrome P450 genes on chromosome 7q21.1. Previously another CYP3A gene, CYP3A3, was thought to exist; however, it is now thought that this sequence represents a transcript variant of CYP3A4. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Feb 2011]
[中文简述(自动翻译):]  该基??因编码的酶的细胞色素P450超家族的成员。细胞色素P450蛋白是催化涉及药物代谢和胆固醇,类固醇和其他脂类的合成许多反应单加氧酶。此蛋白质定位于内质网和它的表达是由糖皮质激素和某些药理学药剂诱导的。这种酶是参与的大约一半在目前使用的药物,包括对乙酰氨基酚,可待因,环孢菌素A,地西泮和红霉素的代谢。酶还代谢一些类固醇和致癌物质。这种基因是细胞色素P450基因在染色体7q21.1群集的一部分。此前另一CYP3A基因??CYP3A3,被认为存在;然而,它现在认为这个序列表示CYP3A4的转录变异体。编码不同同种型的可变剪接转录物变体也已确定。 [由RefSeq的,2011年2月提供]
