The esBAF and ISWI nucleosome remodeling complexes influence occupancy of overlapping dinucleosomes and fragile nucleosomes in murine embryonic stem cells

open access: yesBMC Genomics, 2023
Background Nucleosome remodeling factors regulate the occupancy and positioning of nucleosomes genome-wide through ATP-driven DNA translocation. While many nucleosomes are consistently well-positioned, some nucleosomes and alternative nucleosome ...

The insulator binding protein CTCF positions 20 nucleosomes around its binding sites across the human genome. [PDF]

open access: yesPLoS Genetics, 2008
Chromatin structure plays an important role in modulating the accessibility of genomic DNA to regulatory proteins in eukaryotic cells. We performed an integrative analysis on dozens of recent datasets generated by deep-sequencing and high-density tiling ...

Single molecule analysis of CENP-A chromatin by high-speed atomic force microscopy

open access: yeseLife, 2023
Chromatin accessibility is modulated in a variety of ways to create open and closed chromatin states, both of which are critical for eukaryotic gene regulation.

LPS-Challenged Macrophages Release Microvesicles Coated With Histones

open access: yesFrontiers in Immunology, 2018
Histones are the protein component of nucleosomes, which are the basic packing unit of chromatin. However, histones are also found in the blood, both as components of nucleosomes leaked out from dead cells, or expelled from neutrophils in the active ...

Nucleosomes impede Cas9 access to DNA in vivo and in vitro

open access: yeseLife, 2016
The prokaryotic CRISPR (clustered regularly interspaced palindromic repeats)-associated protein, Cas9, has been widely adopted as a tool for editing, imaging, and regulating eukaryotic genomes.

Specialization of the chromatin remodeler RSC to mobilize partially-unwrapped nucleosomes

open access: yeseLife, 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 ...

Life Cycle Stage-Specific Accessibility of Leishmania donovani Chromatin at Transcription Start Regions

open access: yesmSystems, 2021
Leishmania donovani is a parasitic protist that causes the lethal Kala-azar fever in India and East Africa. Gene expression in Leishmania is regulated by gene copy number variation and inducible translation while RNA synthesis initiates at a small number

Mechanical properties of nucleoprotein complexes determined by nanoindentation spectroscopy

open access: yesNucleus, 2020
The interplay between transcription factors, chromatin remodelers, 3-D organization, and mechanical properties of the chromatin fiber controls genome function in eukaryotes.
