Abstract DNA double-strand breaks (DSBs) must be repaired to ensure cell survival and genomic integrity. In yeast, the Mre11-Rad50-Xrs2 complex (MRX) collaborates with Sae2 to initiate DSB repair. Sae2 stimulates two MRX nuclease activities, endonucl

Abstract The outcome of CRISPR-Cas-mediated genome modifications is dependent on DNA double-strand break (DSB) processing and repair pathway choice. Homology-directed repair (HDR) of protein-blocked DSBs requires DNA end resection that is initiated b

Abstract HROB promotes the MCM8-9 helicase in DNA damage response. To understand how HROB activates MCM8-9, we defined their interaction interface. We showed that HROB makes important yet transient contacts with both MCM8 and MCM9, and binds the MCM8

Abstract DNA double-strand breaks (DSBs) can be repaired by several pathways. In eukaryotes, DSB repair pathway choice occurs at the level of DNA end resection and is controlled by the cell cycle. Upon cell cycle-dependent activation, cyclin-dependen

The Mre11-Rad50 (MR) complex has key functions in the detection, signaling and repair of DNA breaks. Here the authors use transmission electron microscopy to show MR oligomerization is governed by a small beta-sheet protruding from the head domain of

Telomeres suppress the DNA damage response at chromosome ends. Here the authors show that in budding yeast the activity of the MRX complex in DNA repair and DNA damage signaling is inhibited by telomeric protein Rif2 via a short motif at the N-termin

Homologous recombination (HR) is an essential DNA repair pathway for genomic stability. Here the authors show that C17orf53/MCM8IP, an OB-fold containing protein, promotes HR through direct binding and activation of the MCM8-9 helicase complex.

Summary: The Mre11-Rad50-Xrs2 (MRX) complex detects and processes DNA double-strand breaks (DSBs). Its DNA binding and processing activities are regulated by transitions between an ATP-bound state and a post-hydrolysis cutting state that is nucleolyt

Long non-coding RNAs transcribed at DNA damaged sites can play part in DNA damage response. Here the authors reveal that damaged induced lncRNAs can form DNA:RNA hybrids at resected DNA-ends. These hybrids are involved in recruiting HR-mediated repai
