Inhibition of MRN activity by a telomere protein motif
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-terminus.

Chromium and genomic stability [PDF]
Many metals serve as micronutrients which protect against genomic instability. Chromium is most abundant in its trivalent and hexavalent forms. Trivalent chromium has historically been considered an essential element, though recent data indicate that while it can have pharmacological effects and value, it is not essential.

Defending the genome from the enemy within:mechanisms of retrotransposon suppression in the mouse germline [PDF]
The viability of any species requires that the genome is kept stable as it is transmitted from generation to generation by the germ cells. One of the challenges to transgenerational genome stability is the potential mutagenic activity of transposable ...

Unlike bacteria, mammalian cells need to complete DNA replication before segregating their chromosomes for the maintenance of genome integrity. Thus, cells have evolved efficient pathways to restore stalled and/or collapsed replication forks during S ...

The role of Schizosaccharomyces pombe SUMO ligases in genome stability [PDF]
SUMOylation is a post-translational modification that affects a large number of proteins, many of which are nuclear. While the role of SUMOylation is beginning to be elucidated, it is clear that understanding the mechanisms that regulate the process is ...

Background Stress response is mediated by the transcription of stress-responsive genes. The F-box motif protein Saf1p is involved in SCF-E3 ligase mediated degradation of the adenine deaminase, Aah1p upon nutrient stress.

Nuclear DNA and protein content evaluation in Taxus plant cell cultures using multiparameter flow cytometry [PDF]
Plant cell cultures of Taxus provide the most reliable production methods for the anti-cancer drug paclitaxel. In order to comprehend the inherent culture heterogeneity and production variability in cell cultures, it is essential that the cellular ...

A nucleotide resolution map of Top2-linked DNA breaks in the yeast and human genome
Topoisomerase 2 (Top2) is known to resolve DNA topological stress through double strand breaks (DSBs), yet Top2 inhibition has been reported to result in a significant amount of single-strand breaks (SSBs).

TopBP1 interacts with BLM to maintain genome stability but is dispensable for preventing BLM degradation. [PDF]
The Bloom syndrome helicase BLM and topoisomerase-IIβ-binding protein 1 (TopBP1) are key regulators of genome stability. It was recently proposed that BLM phosphorylation on Ser338 mediates its interaction with TopBP1, to protect BLM from ubiquitylation ...

The kinase PLK1 has important roles during cell division, including mitotic entry and bipolar spindle formation. Here, the authors show that PLK1 also functions in centromere protection, with loss leading to DNA unwinding by Bloom’s syndrome helicase and
