DNA end resection: mechanism and control

P Cejka, LS Symington - Annual review of genetics, 2021 - annualreviews.org
DNA double-strand breaks (DSBs) are cytotoxic lesions that threaten genome integrity and
cell viability. Typically, cells repair DSBs by either nonhomologous end joining (NHEJ) or …

The DNA damage response in the chromatin context: A coordinated process

J Dabin, M Mori, SE Polo - Current Opinion in Cell Biology, 2023 - Elsevier
In the cell nucleus, DNA damage signaling and repair machineries operate on a chromatin
substrate, the integrity of which is critical for cell function and viability. Here, we review …

Cohesin regulates homology search during recombinational DNA repair

A Piazza, H Bordelet, A Dumont, A Thierry… - Nature cell …, 2021 - nature.com
Homologous recombination repairs DNA double-strand breaks (DSB) using an intact dsDNA
molecule as a template. It entails a homology search step, carried out along a conserved …

[HTML][HTML] Chromatin remodeling and spatial concerns in DNA double-strand break repair

JA Downs, SM Gasser - Current Opinion in Cell Biology, 2024 - Elsevier
The substrate for the repair of DNA damage in living cells is not DNA but chromatin.
Chromatin bears a range of modifications, which in turn bind ligands that compact or open …

[HTML][HTML] The mechanobiology of nuclear phase separation

DSW Lee, AR Strom, CP Brangwynne - APL bioengineering, 2022 - pubs.aip.org
The cell nucleus can be thought of as a complex, dynamic, living material, which functions to
organize and protect the genome and coordinate gene expression. These functions are …

Damage-induced chromatome dynamics link Ubiquitin ligase and proteasome recruitment to histone loss and efficient DNA repair

K Challa, CD Schmid, S Kitagawa, A Cheblal… - Molecular Cell, 2021 - cell.com
Eukaryotic cells package their genomes around histone octamers. In response to DNA
damage, checkpoint activation in yeast induces core histone degradation resulting in 20 …

Loss of cytoplasmic actin filaments raises nuclear actin levels to drive INO80C-dependent chromosome fragmentation

V Hurst, CB Gerhold, CVD Tarashev, K Challa… - Nature …, 2024 - nature.com
Loss of cytosolic actin filaments upon TORC2 inhibition triggers chromosome fragmentation
in yeast, which results from altered base excision repair of Zeocin-induced lesions. To find …

Mechanism of homology search expansion during recombinational DNA break repair in Saccharomyces cerevisiae

A Dumont, N Mendiboure, J Savocco, L Anani… - Molecular Cell, 2024 - cell.com
Homology search is a central step of DNA double-strand break (DSB) repair by homologous
recombination (HR). How it operates in cells remains elusive. We developed a Hi-C-based …

SUMO in the regulation of DNA repair and transcription at nuclear pores

SM Gasser, F Stutz - FEBS letters, 2023 - Wiley Online Library
Two related post‐translational modifications, the covalent linkage of Ubiquitin and the Small
Ubiquitin‐related MOdifier (SUMO) to lysine residues, play key roles in the regulation of both …
