Biochemical characterization of the placeholder nucleosome for DNA hypomethylation maintenance
Biochemistry and Biophysics Reports, 2019 DNA methylation functions as a prominent epigenetic mark, and its patterns are transmitted to the genomes of offspring. The nucleosome containing the histone H2A.Z variant and histone H3K4 mono-methylation acts as a “placeholder” nucleosome for DNA ...

Nucleosome Positioning, Nucleosome Spacing and the Nucleosome Code [PDF]
Journal of Biomolecular Structure and Dynamics, 2010 Nucleosome positioning has been the subject of intense study for many years. The properties of micrococcal nuclease, the enzyme central to these studies, are discussed. The various methods used to determine nucleosome positions in vitro and in vivo are reviewed critically.

The histone chaperone FACT modulates nucleosome structure by tethering its components
Life Science Alliance, 2018 The histone chaperone FACT functions by tethering partial components of the nucleosome, thereby assisting nucleosome disassembly and reassembly during transcription.

Structural and biochemical analyses of monoubiquitinated human histones H2B and H4 [PDF]
Open Biology, 2016 Monoubiquitination is a major histone post-translational modification. In humans, the histone H2B K120 and histone H4 K31 residues are monoubiquitinated and may form transcriptionally active chromatin.

Nucleosome—nucleosome interaction in chromatin
FEBS Letters, 1979 The available data suggest that transcriptional activity of chromatin is connected with its structural changes [ 1,2]. According to the electron microscope evidence, the elementary 100 A chromatin thread can exist in two main states, i.e., in a compact state, which is characterized by tight packing of nucleosomes and in an extended state when the ...

Contributions of histone H3 nucleosome core surface mutations to chromatin structures, silencing and DNA repair. [PDF]
PLoS ONE, 2011 Histone H3 mutations in residues that cluster in a discrete region on the nucleosome surface around lysine 79 of H3 affect H3-K79 methylation, impair transcriptional silencing in subtelomeric chromatin, and reveal distinct contributions of histone H3 to ...

Circulating Nucleosomes and Nucleosome Modifications as Biomarkers in Cancer [PDF]
Cancers, 2017 Traditionally the stratification of many cancers involves combining tumour and clinicopathological features (e.g., patient age; tumour size, grade, receptor status and location) to inform treatment options and predict recurrence risk and survival. However, current biomarkers often require invasive excision of the tumour for profiling, do not allow ...

Manipulating chromatin architecture in C. elegans
Epigenetics & Chromatin, 2022 Background Nucleosome-mediated chromatin compaction has a direct effect on the accessibility of trans-acting activators and repressors to DNA targets and serves as a primary regulatory agent of genetic expression. Understanding the nature and dynamics of
