Here we describe two separation-of-functions alleles, mre11-S499P and rad50-A78T, which we show to specifically affect Tel1 activation without impairing MRX functions in DSB repair. Both Mre11-S499P and Rad50-A78T reduce Tel1-MRX interaction leading to poor Tel1 association at DSBs and consequent loss of Tel1 activation
Title: The ATP-bound conformation of the Mre11-Rad50 complex is essential for Tel1/ATM activation.
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.
Title: Structurally distinct Mre11 domains mediate MRX functions in resection, end-tethering and DNA damage resistance.
Phosphorylation of ssDNA endodeoxyribonuclease SAE2 (Sae2)does not affect its overall capacity to interact with Mre11-Rad50-Xrs2 (MRX), it controls the specific physical and functional interaction with the MRX subunit Rad50, which is a prerequisite for the regulation of the Mre11 nuclease.
