coq-8 encodes a putative protein kinase orthologous to ABC1 (COQ8) from S. cerevisiae and UbiB from E. coli, and paralogous to C. elegans D2023.6 and its (uncharacterized) eukaryotic orthologs; COQ-8 is required for ubiquinone (coenzyme Q9) biosynthesis and for normally short lifespan; alternative hypotheses for COQ-8's biochemical function are that it is a 2-polyprenylphenol 6-hydroxylase, or that it may activate proteins necessary for monooxygenase activity via phosphorylation; coq-8 is expressed in several tissues during larval development, but in later adult life its expression is restricted to neurons; coq-8 mutants have slowed pharyngeal pumping, and eventually arrest as paralysed larvae before dying; coq-8(RNAi) animals have reduced levels of coenzyme Q9 and superoxide, and have abnormally long lifespans; coq-8 mutants are not rescued by dietary coenzyme Q.
