CYP3A

Cytochrome P450, family 3, subfamily A, also known as CYP3A, is a human is_associated_with::gene.

The CYP3A locus includes all the known members of the 3A subfamily of the is_associated_with::cytochrome P450 superfamily of genes. These genes encode is_associated_with::monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. The CYP3A cluster consists of four genes: The region also contains two is_associated_with::pseudogenes: as well as several extra exons which may or may not be included in transcripts produced from this region. Previously another CYP3A member, CYP3A3, was thought to exist; however, it is now thought that this sequence represents a transcript variant of CYP3A4.
