CYP3A4 encodes the human gene, Cytochrome P450 family 3 subfamily A member 4. It may also be known as: Cytochrome P450 3A4; 1,8-cineole 2-exo-monooxygenase; Albendazole monooxygenase; Albendazole sulfoxidase; CYPIIIA3; CYPIIIA4; Cytochrome P450 3A3; Cytochrome P450 HLp; Cytochrome P450 NF-25; Cytochrome P450-PCN1; Nifedipine oxidase; Quinine 3-monooxygenase; Taurochenodeoxycholate 6-alpha-hydroxylase; Cytochrome P450 3A4 ; CP33; CP34; CYP3A3; NF-25; P450C3; P450PCN1; cytochrome P450, family 3, subfamily A, polypeptide 4. The encoded protein is an enzyme with an amino acid length of 503 and a mass of 57.3 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Frog, Chicken.
