Chromatin accessibility: a window into the genome [PDF]

open access: yesEpigenetics & Chromatin, 2014
Transcriptional activation throughout the eukaryotic lineage has been tightly linked with disruption of nucleosome organization at promoters, enhancers, silencers, insulators and locus control regions due to transcription factor binding. Regulatory DNA thus coincides with open or accessible genomic sites of remodeled chromatin.

Computational modeling of chromatin accessibility identified important epigenomic regulators

open access: yesBMC Genomics, 2022
Chromatin accessibility is essential for transcriptional activation of genomic regions. It is well established that transcription factors (TFs) and histone modifications (HMs) play critical roles in chromatin accessibility regulation. However, there is a

Reorganization of postmitotic neuronal chromatin accessibility for maturation of serotonergic identity

open access: yeseLife, 2022
Assembly of transcriptomes encoding unique neuronal identities requires selective accessibility of transcription factors to cis-regulatory sequences in nucleosome-embedded postmitotic chromatin.

Evolution and genetic architecture of chromatin accessibility and function in yeast. [PDF]

open access: yesPLoS Genetics, 2014
Chromatin accessibility is an important functional genomics phenotype that influences transcription factor binding and gene expression. Genome-scale technologies allow chromatin accessibility to be mapped with high-resolution, facilitating detailed ...

Transcription factor access to chromatin [PDF]

open access: yesNucleic Acids Research, 1997
The question of how sequence-specific transcription factors access their cognate sites in nucleosomally organized DNA is discussed on the basis of genomic footprinting data and chromatin reconstitution experiments. A classification of factors into two categories is proposed: (i) initiator factors which are able to bind their target sequences within ...

SeATAC: a tool for exploring the chromatin landscape and the role of pioneer factors

open access: yesGenome Biology, 2023
Assay for Transposase-Accessible Chromatin with sequencing (ATAC-seq) reveals chromatin accessibility across the genome. Currently, no method specifically detects differential chromatin accessibility.

A chromatin accessibility landscape during early adipogenesis of human adipose-derived stem cells

open access: yesAdipocyte, 2022
Obesity has become a serious global public health problem; a deeper understanding of systemic change of chromatin accessibility during human adipogenesis contributes to conquering obesity and its related diseases.

Profiling single-cell chromatin accessibility in plants

open access: yesSTAR Protocols, 2021
Summary: Coupling assay for transposase-accessible chromatin sequencing (ATAC-seq) with microfluidic separation and cellular barcoding has emerged as a powerful approach to investigate chromatin accessibility of individual cells.

Cations and the accessibility of chromatin to nucleases [PDF]

open access: yesNucleic Acids Research, 1979
When rat liver nuclei prepared with polyamines as stabilising cations are digested with DNAase II, release of both inactive chromatin and Mg-soluble, active chromatin is greatly reduced, in comparison to digestion of liver nuclei prepared with Mg2+ as stabilising cation.
