Function Catalyzes the prenylation of para-hydroxybenzoate (PHB) with an all-trans polyprenyl group. Mediates the second step in the final reaction sequence of coenzyme Q (CoQ) biosynthesis, which is the condensation of the polyisoprenoid side chain with PHB. {ECO:0000269PubMed:15153069}.
Subcellular Localization Mitochondrion membrane {ECO:0000305}; Multi- pass membrane protein {ECO:0000305}.
Disease Associations Coenzyme Q10 deficiency, primary, 1 (COQ10D1) [MIM:607426]: An autosomal recessive disorder with variable manifestations consistent with 5 major phenotypes. The phenotypes include an encephalomyopathic form with seizures and ataxia; a multisystem infantile form with encephalopathy, cardiomyopathy and renal failure; a predominantly cerebellar form with ataxia and cerebellar atrophy; Leigh syndrome with growth retardation; and an isolated myopathic form. {ECO:0000269PubMed:16400613, ECO:0000269PubMed:17855635}. Note=The disease is caused by mutations affecting the gene represented in this entry.Multiple system atrophy 1 (MSA1) [MIM:146500]: A progressive neurodegenerative disorder clinically characterized by parkinsonism, cerebellar ataxia, and autonomic, urogenital, and pyramidal dysfunction in various combinations. Pathologically, it is characterized by degeneration of striatonigral and olivopontocerebellar structures, and glial cytoplasmic inclusions that consist of abnormally phosphorylated alpha-synuclein or tau. {ECO:0000269PubMed:23758206}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
Tissue Specificity Widely expressed. Present in all of the tissues tested. Expressed at higher level in skeletal muscle, adrenal glands and the heart. {ECO:0000269PubMed:15153069}.
