Echoed induction of nucleotide variants and chromosomal structural variants in cancer cells

open access: yesScientific Reports, 2022
Generally, the number of single-nucleotide variants (SNVs) in somatic cells increases with age, which is expected for replication errors. The number of SNVs in cancer cells, however, is often much higher than that in somatic cells, raising the question ...

Schizosaccharomyces pombe Rtf2 is important for replication fork barrier activity of RTS1 via splicing of Rtf1

open access: yeseLife, 2023
Arrested replication forks, when restarted by homologous recombination, result in error-prone DNA syntheses and non-allelic homologous recombination. Fission yeast RTS1 is a model fork barrier used to probe mechanisms of recombination-dependent restart ...

Replication dynamics of recombination-dependent replication forks

open access: yesNature Communications, 2021
Replication forks that are stalled at obstacles on the DNA template can be restarted by homologous recombination. Here, the authors show replication dynamics during homologous recombination-dependent replication fork restart by combining polymerase usage

Live-cell single-molecule tracking highlights requirements for stable Smc5/6 chromatin association in vivo

open access: yeseLife, 2021
The essential Smc5/6 complex is required in response to replication stress and is best known for ensuring the fidelity of homologous recombination. Using single-molecule tracking in live fission yeast to investigate Smc5/6 chromatin association, we show ...

CRISPR-Associated Primase-Polymerases are implicated in prokaryotic CRISPR-Cas adaptation

open access: yesNature Communications, 2021
CAPPs are putative Primase-Polymerases associated with CRISPR-Cas operons. Here, the authors show CAPPs genetic and physical association with Cas1 and Cas2, their capacity to function as DNA-dependent DNA primases and DNA polymerases, and that Cas1-Cas2 ...

Inhibition of MRN activity by a telomere protein motif

open access: yesNature Communications, 2021
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.

Mind the replication gap

open access: yesRoyal Society Open Science, 2021
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 ...

Genetic interaction between RLM1 and F-box motif encoding gene SAF1 contributes to stress response in Saccharomyces cerevisiae

open access: yesGenes and Environment, 2021
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.

A nucleotide resolution map of Top2-linked DNA breaks in the yeast and human genome

open access: yesNature Communications, 2019
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).

PLK1 facilitates chromosome biorientation by suppressing centromere disintegration driven by BLM-mediated unwinding and spindle pulling

open access: yesNature Communications, 2019
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
