Predicted to enable several functions, including caffeine oxidase activity; iron ion binding activity; and monooxygenase activity. Acts upstream of or within regulation of gene expression and response to bacterium. Predicted to be located in endoplasmic reticulum membrane. 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).
