Conservation of Nucleosome Positions in Duplicated and Orthologous Gene Pairs

open access: yesThe Scientific World Journal, 2012
Although nucleosome positions tend to be conserved in gene promoters, whether they are conserved in duplicated and orthologous genes is unknown. In order to elucidate how nucleosome positions are conserved between duplicated and orthologous gene pairs, I

Evidence of association between Nucleosome Occupancy and the Evolution of Transcription Factor Binding Sites in Yeast

open access: yesBMC Evolutionary Biology, 2011
Background Divergence of transcription factor binding sites is considered to be an important source of regulatory evolution. The associations between transcription factor binding sites and phenotypic diversity have been investigated in many model ...

Ion counting demonstrates a high electrostatic field generated by the nucleosome

open access: yeseLife, 2019
In eukaryotes, a first step towards the nuclear DNA compaction process is the formation of a nucleosome, which is comprised of negatively charged DNA wrapped around a positively charged histone protein octamer.

Dynamic nucleosome landscape elicits a noncanonical GATA2 pioneer model

open access: yesNature Communications, 2022
Here the authors provide a multi-omic study of the nucleosome landscape in LNCaP cells and observe nine functional nucleosome states each with characteristic nucleosome footprints.

Nucleosomes affect local transformation efficiency [PDF]

open access: yes, 2012
Genetic transformation is a natural process during which foreign DNA enters a cell and integrates into the genome. Apart from its relevance for horizontal gene transfer in nature, transformation is also the cornerstone of today's recombinant gene ...

Genomic sequence is highly predictive of local nucleosome depletion. [PDF]

open access: yesPLoS Computational Biology, 2008
The regulation of DNA accessibility through nucleosome positioning is important for transcription control. Computational models have been developed to predict genome-wide nucleosome positions from DNA sequences, but these models consider only nucleosome ...

Thermodynamic modeling of genome-wide nucleosome depleted regions in yeast.

open access: yesPLoS Computational Biology, 2021
Nucleosome positioning in the genome is essential for the regulation of many nuclear processes. We currently have limited capability to predict nucleosome positioning in vivo, especially the locations and sizes of nucleosome depleted regions (NDRs). Here,

Crystal Structure of the LSD1/CoREST Histone Demethylase Bound to Its Nucleosome Substrate.

open access: yesMolecules and Cells, 2020
LSD1 (lysine specific demethylase; also known as KDM1A), the first histone demethylase discovered, regulates cell-fate determination and is overexpressed in multiple cancers.

Nucleosome footprinting in plasma cell-free DNA for the pre-surgical diagnosis of ovarian cancer

open access: yesnpj Genomic Medicine, 2022
Fragmentation patterns of plasma cell-free DNA (cfDNA) are known to reflect nucleosome positions of cell types contributing to cfDNA. Based on cfDNA fragmentation patterns, the deviation in nucleosome footprints was quantified between diagnosed ovarian ...

The histone chaperones Nap1 and Vps75 bind histones H3 and H4 in a tetrameric conformation [PDF]

open access: yes, 2011
Histone chaperones physically interact with histones to direct proper assembly and disassembly of nucleosomes regulating diverse nuclear processes such as DNA replication, promoter remodeling, transcription elongation, DNA damage, and histone variant ...
