Summaries for CYP2A6 Gene

Entrez Gene Summary for CYP2A6 Gene

  • This gene, CYP2A6, 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 hydroxylate coumarin, and also metabolizes nicotine, aflatoxin B1, nitrosamines, and some pharmaceuticals. Individuals with certain allelic variants are said to have a poor metabolizer phenotype, meaning they do not efficiently metabolize coumarin or nicotine. This gene is part of a large cluster of cytochrome P450 genes from the CYP2A, CYP2B and CYP2F subfamilies on chromosome 19q. The gene was formerly referred to as CYP2A3; however, it has been renamed CYP2A6. [provided by RefSeq, Jul 2008]

GeneCards Summary for CYP2A6 Gene

CYP2A6 (Cytochrome P450 Family 2 Subfamily A Member 6) is a Protein Coding gene. Diseases associated with CYP2A6 include Nicotine Dependence, Protection Against and Coumarin Resistance. Among its related pathways are Cytochrome P450 - arranged by substrate type and Phenytoin Pathway, Pharmacokinetics. GO annotations related to this gene include enzyme binding and heme binding. An important paralog of this gene is CYP2A7.
