CYP2A7 (cytochrome P450 family 2 subfamily A polypeptide 7) is a protein that in humans is encoded by the CYP2A7 gene.This gene 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; its substrate has not yet been determined.
