TRF2 controls telomeric nucleosome organization in a cell cycle phase-dependent manner [PDF]
, 2012 Mammalian telomeres stabilize chromosome ends as a result of their assembly into a peculiar form of chromatin comprising a complex of non-histone proteins named shelterin.

Statistical-mechanical lattice models for protein-DNA binding in chromatin [PDF]
, 2010 Statistical-mechanical lattice models for protein-DNA binding are well established as a method to describe complex ligand binding equilibriums measured in vitro with purified DNA and protein components. Recently, a new field of applications has opened up

Nucleosomes inhibit target cleavage by CRISPR-Cas9 in vivo
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance The efficiency of genome editing with CRISPR-Cas9 can vary widely at different targets and in different cells. Some of this variability may be due to the inherent quality of different guide RNAs, but it may also depend on the cellular ...

Specialization of the chromatin remodeler RSC to mobilize partially-unwrapped nucleosomes
eLife, 2020 SWI/SNF-family chromatin remodeling complexes, such as S. cerevisiae RSC, slide and eject nucleosomes to regulate transcription. Within nucleosomes, stiff DNA sequences confer spontaneous partial unwrapping, prompting whether and how SWI/SNF-family ...

Arginine mutation alters binding of a human monoclonal antibody to antigens linked to systemic lupus erythematosus and the antiphospholipid syndrome [PDF]
, 2007 Objective: Previous studies have shown the importance of somatic mutations and arginine residues in the complementarity-determining regions (CDRs) of pathogenic anti-double-stranded DNA (anti-dsDNA) antibodies in human and murine lupus, and in studies of

eLife, 2019 Tardigrades, also known as water bears, are animals that can survive extreme conditions. The tardigrade Ramazzottius varieornatus contains a unique nuclear protein termed Dsup, for damage suppressor, which can increase the resistance of human cells to ...

ISRN Molecular Biology, 2012 Nucleosome positioning is not only related to genomic DNA compaction but also to other biological functions. After the chromatin is digested by micrococcal nuclease, nucleosomal (nucleosome-bound) DNA fragments can be sequenced and mapped on the genomic DNA sequence.

DNA-encoded nucleosome occupancy is associated with transcription levels in the human malaria parasite Plasmodium falciparum. [PDF]
, 2014 BackgroundIn eukaryotic organisms, packaging of DNA into nucleosomes controls gene expression by regulating access of the promoter to transcription factors.

Precise genome-wide mapping of single nucleosomes and linkers in vivo
Genome Biology, 2018 We developed a chemical cleavage method that releases single nucleosome dyad-containing fragments, allowing us to precisely map both single nucleosomes and linkers with high accuracy genome-wide in yeast.
