Protection against oxidative damage caused by excessive reactive oxygen species (ROS) by an antioxidant network is essential for the health of tissues, especially in the cardiovascular system. Here, we identified a gene with important antioxidant features by analyzing a null allele of zebrafish ubiad1, called barolo (bar). bar mutants show specific cardiovascular failure due to oxidative stress and ROS-mediated cellular damage. Human UBIAD1 is a nonmitochondrial prenyltransferase that synthesizes CoQ10 in the Golgi membrane compartment. Loss of UBIAD1 reduces the cytosolic pool of the antioxidant CoQ10 and leads to ROS-mediated lipid peroxidation in vascular cells. Surprisingly, inhibition of eNOS prevents Ubiad1-dependent cardiovascular oxidative damage, suggesting a crucial role for this enzyme and nonmitochondrial CoQ10 in NO signaling. These findings identify UBIAD1 as a nonmitochondrial CoQ10-forming enzyme with specific cardiovascular protective function via the modulation of eNOS activity. ► UBIAD1 is a Golgi prenyltransferase ► UBIAD1 contributes to the nonmitochondrial pool of CoQ10 ► UBIAD1 protects cardiovascular tissues from NOS-dependent oxidative damage ► UBIAD1 is a target for therapeutic strategies by limiting the side effects of statins UBIAD1 is identified as a nonmitochondrial CoQ10 biosynthetic enzyme required for oxidative damage protection. Through CoQ10 synthesis, UBIAD1 modulates endothelial nitric oxide synthase activity and nitric oxide signaling necessary for cardiovascular development and homeostasis.
