|abstract=CoQ is an essential electron carrier in the mitochondrial respiratory chain of both eukaryotes and prokaryotes. It consists of a benzoquinone head group and a hydrophobic polyisoprenoid tail. The genes (COQ1-9) involved in CoQ biosynthesis have been characterized in yeast. In this study, we generated and molecularly characterized a mutant allele of a novel Drosophila gene, sbo, which encodes a protein that is predicted to catalyze the prenylation of p-hydroxybenzoate with the isoprenoid chain during the process of CoQ synthesis. Expression of sbo in yeast rescues the lethality of ∆[[COQ2]] mutant cells, indicating that sbo is a functional homolog of [[COQ2]]. HPLC results show that the levels of CoQ(9) and CoQ(10) were significantly reduced in sbo heterozygous adult flies. Furthermore, the mean lifespans of males and females heterozygous for sbo are extended by 12.5% and 30.8%, respectively. Homozygous sbo animals exhibit reduced activities of the insulin/insulin-like growth factor signaling (IIS) pathway. Taken together, we conclude that sbo is an essential gene for Drosophila development, mutation of which leads to an extension of lifespan most likely by altering endogenous CoQ biosynthesis.
