Enables monooxygenase activity. Acts upstream of or within response to bacterium. Predicted to be located in endoplasmic reticulum membrane. Is expressed in several structures, including alimentary system; genitourinary system; musculoskeletal system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in B-lymphoblastic leukemia/lymphoma; acute lymphoblastic leukemia; chronic myeloid leukemia; essential hypertension; and familial Mediterranean fever. Orthologous to several human genes including CYP3A4 (cytochrome P450 family 3 subfamily A member 4) and CYP3A5 (cytochrome P450 family 3 subfamily A member 5).
