Data show that ssDNA endodeoxyribonuclease SAE2 (Sae2) cooperates with the Mre11-Rad50-Xrs2 (MRX) complex to initiate resection of DNA double-strand breaks (DSBs) and to maintain the DSB ends in close proximity to allow their repair. | Structurally distinct Mre11 domains mediate MRX functions in resection, end-tethering and DNA damage resistance.
