Ubiquitin system factors are critical regulators of DNA repair pathways. Through a functional genetic screen, the authors identify a novel role of ubiquitin-conjugating enzyme UBE2D3 in promoting DNA repair at deprotected telomeres by limiting the accumulation of RNF168 and promoting ample ATM-dependent phosphorylation of KAP1.
