DNA double-strand breaks (DSBs) can be repaired by non-homologous end-joining (NHEJ) or homologous recombination (HR). HR is initiated by nucleolytic degradation of the DSB ends in a process termed resection. The Mre11-Rad50-Xrs2/NBS1 (MRX/N) complex is a multifunctional enzyme that, aided by the Sae2/CtIP protein, promotes DSB resection and maintains the DSB ends tethered to each other to facilitate their re-ligation. Furthermore, it activates the protein kinase Tel1/ATM, which initiates DSB signaling. In Saccharomyces cerevisiae, thes
