Predicted to enable several functions, including heme binding activity; iron ion binding activity; and monooxygenase activity. Is expressed in adult head and embryonic/larval midgut. 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 CYP3A7-CYP3A51P (CYP3A7-CYP3A51P readthrough); CYP3A4 (cytochrome P450 family 3 subfamily A member 4); and CYP3A43 (cytochrome P450 family 3 subfamily A member 43).
