Mammalian telomeres and their partnership with lamins [PDF]
, 2016 Chromosome ends are complex structures, which require a panel of factors for their elongation, replication, and protection. We describe here the mechanics of mammalian telomeres, dynamics and maintainance in relation to lamins.

Modeling cancer genomic data in yeast reveals selection against ATM function during tumorigenesis [PDF]
, 2020 The DNA damage response (DDR) comprises multiple functions that collectively preserve genomic integrity and suppress tumorigenesis. The Mre11 complex and ATM govern a major axis of the DDR and several lines of evidence implicate that axis in tumor ...

PLoS Genetics, 2020 DNA double-strand breaks (DSBs) are toxic forms of DNA damage that must be repaired to maintain genome integrity. Telomerase can act upon a DSB to create a de novo telomere, a process that interferes with normal repair and creates terminal deletions.

Telomere maintenance and the DNA damage response: a paradoxical alliance
Frontiers in Cell and Developmental BiologyTelomeres are the protective caps at the ends of linear chromosomes of eukaryotic organisms. Telomere binding proteins, including the six components of the complex known as shelterin, mediate the protective function of telomeres.

The Protein hSnm1B Is Stabilized When Bound to the Telomere-binding Protein TRF2 [PDF]
Journal of Biological Chemistry, 2008 hSnm1B is member of the SNM family of exonucleases involved in DNA processing and is known to be localized to telomeres via binding to the telomere-binding protein TRF2. Here we demonstrate that the C terminus of hSnm1B facilitates the concentration of hSnm1B on telomeres by promoting ubiquitin-mediated degradation of hSnm1B that is not localized to ...

G-quadruplexes and G-quadruplex ligands: targets and tools in antiviral therapy [PDF]
, 2018 G-quadruplexes (G4s) are non-canonical nucleic acids secondary structures that form within guanine-rich strands of regulatory genomic regions. G4s have been extensively described in the human genome, especially in telomeres and oncogene promoters; in ...

Studying DNA Double-Strand Break Repair: An Ever-Growing Toolbox [PDF]
, 2020 To ward off against the catastrophic consequences of persistent DNA double-strand breaks (DSBs), eukaryotic cells have developed a set of complex signaling networks that detect these DNA lesions, orchestrate cell cycle checkpoints and ultimately lead to ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
