Cyp2a3 - cytochrome P450, family 2, subfamily a, polypeptide 3

Predicted to enable heme binding activity and monooxygenase activity. Predicted to be involved in coumarin metabolic process; epoxygenase P450 pathway; and xenobiotic metabolic process. Predicted to act upstream of or within cellular response to cadmium ion; heme metabolic process; and response to stilbenoid. Predicted to be located in endoplasmic reticulum membrane. Predicted to be integral component of membrane. Predicted to be active in cytoplasm and intracellular membrane-bounded organelle. Human ortholog(s) of this gene implicated in nicotine dependence and warfarin resistance. Orthologous to human CYP2A13 (cytochrome P450 family 2 subfamily A member 13); CYP2A6 (cytochrome P450 family 2 subfamily A member 6); and CYP2A7 (cytochrome P450 family 2 subfamily A member 7).
