Coordinated nuclease activities counteract Ku at single-ended DNA double-strand breaks

Homologous recombination requires end resection of the DNA at the site of the break, however the Ku dimer can sequester single-ended double-strand breaks. Here the authors show that ATM-dependent phosphorylation of CtIP, along with the actions of Mre11, impair the stable loading of Ku onto DNA.
