Predicted to enable 2-octoprenyl-3-methyl-6-methoxy-1,4-benzoquinone hydroxylase activity and chromatin binding activity. Involved in response to xenobiotic stimulus and ubiquinone biosynthetic process. Predicted to be located in mitochondrion. Predicted to be active in mitochondrial inner membrane and nucleus. Human ortholog(s) of this gene implicated in primary coenzyme Q10 deficiency 8. Orthologous to human COQ7 (coenzyme Q7, hydroxylase). [provided by Alliance of Genome Resources, Apr 2022]
