The Ies6 subunit is essential for INO80-mediated nucleosome organization [PDF]
Scientific ReportsATP-dependent nucleosome remodelers of the INO80 family regulate chromatin by sliding, spacing and positioning nucleosomes. The INO80 remodeler is organized into structural modules that regulate its remodeling activity.

Structural Transition of the Nucleosome during Transcription Elongation
Cells, 2023 In eukaryotes, genomic DNA is tightly wrapped in chromatin. The nucleosome is a basic unit of chromatin, but acts as a barrier to transcription. To overcome this impediment, the RNA polymerase II elongation complex disassembles the nucleosome during ...

Predicting human nucleosome occupancy from primary sequence. [PDF]
PLoS Computational Biology, 2008 Nucleosomes are the fundamental repeating unit of chromatin and comprise the structural building blocks of the living eukaryotic genome. Micrococcal nuclease (MNase) has long been used to delineate nucleosomal organization.

NucleoMap: A computational tool for identifying nucleosomes in ultra-high resolution contact maps.
PLoS Computational Biology, 2022 Although poorly positioned nucleosomes are ubiquitous in the eukaryotic genome, they are difficult to identify with existing nucleosome identification methods.

H3.3-H4 tetramer splitting events feature cell-type specific enhancers. [PDF]
PLoS Genetics, 2013 Previously, we reported that little canonical (H3.1-H4)(2) tetramers split to form "hybrid" tetramers consisted of old and new H3.1-H(4) dimers, but approximately 10% of (H3.3-H4)2 tetramers split during each cell cycle.

Nucleosome Organization in Human Embryonic Stem Cells. [PDF]
PLoS ONE, 2015 The fundamental repeating unit of eukaryotic chromatin is the nucleosome. Besides being involved in packaging DNA, nucleosome organization plays an important role in transcriptional regulation and cellular identity.

The effect of micrococcal nuclease digestion on nucleosome positioning data. [PDF]
PLoS ONE, 2010 Eukaryotic genomes are packed into chromatin, whose basic repeating unit is the nucleosome. Nucleosome positioning is a widely researched area. A common experimental procedure to determine nucleosome positions involves the use of micrococcal nuclease ...

Genome Biology, 2021 We develop a novel computational method, NucHMM, to identify functional nucleosome states associated with cell type-specific combinatorial histone marks and nucleosome organization features such as phasing, spacing and positioning. We test it on publicly

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 ...

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.
