Summary
COQ5 (coenzyme Q5, methyltransferase, HGNC:28722) is a protein-coding gene on chromosome 12q24.31, encoding 2-methoxy-6-polyprenyl-1,4-benzoquinol methylase, mitochondrial (Q5HYK3). Methyltransferase required for the conversion of 2-decaprenyl-6-methoxy-1,4-benzoquinol (DDMQH2) to 2-decaprenyl-3-methyl-6-methoxy-1,4-benzoquinol (DMQH2). It is a selective cancer dependency (DepMap: 22.4% of cell lines).
Enables 2-methoxy-6-polyprenyl-1,4-benzoquinol methyltransferase activity. Involved in methylation and ubiquinone biosynthetic process. Located in mitochondrial inner membrane and mitochondrial matrix. Part of ubiquinone biosynthesis complex. Implicated in primary coenzyme Q10 deficiency 9.

Function. Methyltransferase required for the conversion of 2-decaprenyl-6-methoxy-1,4-benzoquinol (DDMQH2) to 2-decaprenyl-3-methyl-6-methoxy-1,4-benzoquinol (DMQH2).
Subunit / interactions. Component of a multi-subunit COQ enzyme complex, composed of at least COQ3, COQ4, COQ5, COQ6, COQ7 and COQ9. Interacts with PYURF; the interaction is direct, stabilizes COQ5 protein and associates PYURF with COQ enzyme complex.
Subcellular location. Mitochondrion inner membrane.
Tissue specificity. Widely expressed, with highest levels in liver, lung, placenta and skeletal muscle.
Disease relevance. Coenzyme Q10 deficiency, primary, 9 (COQ10D9) [MIM:619028] A form of coenzyme Q10 deficiency, 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. COQ10D9 patients show cerebellar ataxia with cerebellar atrophy. Additional features include generalized tonic-clonic seizures, and cognitive disability. Disease onset is in the first decade of life. The disease may be caused by variants affecting the gene represented in this entry.
Pathway. Cofactor biosynthesis; ubiquinone biosynthesis.
Similarity. Belongs to the class I-like SAM-binding methyltransferase superfamily. MenG/UbiE family.
