Summary: Homologous recombination is initiated by the nucleolytic degradation (resection) of DNA double-strand breaks (DSBs). DSB resection is a two-step process. In the short-range step, the MRX (Mre11-Rad50-Xrs2) complex, together with Sae2, incise

Summary: DNA damage elicits a checkpoint response depending on the Mec1/ATR kinase, which detects the presence of single-stranded DNA and activates the effector kinase Rad53/CHK2. In Saccharomyces cerevisiae, one of the signaling circuits leading to

The histone folding protein Dpb4 forms histone-like dimers within the ISW2 complex and the Pol ε complex in S. cerevisiae. Here the authors reveal insights into two distinct functions that Dpb4 exerts at DSBs depending on its interactors.

Studies performed in the yeasts Saccharomyces cerevisiae and Schizosaccharomyces pombe have led the way in defining the DNA damage checkpoint and in identifying most of the proteins involved in this regulatory network, which turned out to have struct

Repair of DNA double-strand breaks (DSBs) by homologous recombination (HR) requires that the 5'-terminated DNA strands are resected to generate single-stranded DNA overhangs. This process is initiated by a short-range resection catalyzed by the MRX (

Early work by Muller and McClintock discovered that the physical ends of linear chromosomes, named telomeres, possess an inherent ability to escape unwarranted fusions. Since then, extensive research has shown that this special feature relies on spec

DNA double-strand breaks (DSBs) are highly cytotoxic lesions that must be repaired to ensure genomic stability and avoid cell death. The cellular response to DSBs is initiated by the evolutionarily conserved Mre11-Rad50-Xrs2/NBS1 (MRX/MRN) complex th

The MRX complex together with Sae2 initiates resection of DNA double-strand breaks (DSBs) to generate single-stranded DNA (ssDNA) that triggers homologous recombination. The absence of Sae2 not only impairs DSB resection, but also causes prolonged MR

DNA is exposed to both endogenous and exogenous DNA damaging agents that chemically modify it. To counteract the deleterious effects exerted by DNA lesions, eukaryotic cells have evolved a network of cellular pathways, termed DNA damage response (DDR

In Saccharomyces cerevisiae, the protein kinase A (PKA) plays a central role in the control of metabolism, stress resistance and cell cycle progression. In a previous work, we used a FRET-based A-kinase activity reporter (AKAR3 probe) to monitor chan
