Predicted to enable 4-hydroxy-3-all-trans-hexaprenylbenzoate oxygenase activity. Predicted to be involved in ubiquinone biosynthetic process. Predicted to be located in mitochondrial inner membrane. Predicted to be part of ubiquinone biosynthesis complex. Predicted to be active in mitochondrion. Is expressed in several structures, including adult head; adult heart; dorsal pharyngeal muscle cell; gut section; and larval muscle system. Used to study nephrotic syndrome and primary coenzyme Q10 deficiency 6. Human ortholog(s) of this gene implicated in primary coenzyme Q10 deficiency 6. Orthologous to human COQ6 (coenzyme Q6, monooxygenase).
