Perturbation of chromatin structure globally affects localization and recruitment of splicing factors [PDF]

, 2012
Chromatin structure is an important factor in the functional coupling between transcription and mRNA processing, not only by regulating alternative splicing events, but also by contributing to exon recognition during constitutive splicing.

Dynamic chromatin: concerted nucleosome remodelling and acetylation [PDF]

, 2005
The flexibility of chromatin that enables translation of environmental cues into changes in genome utilisation, relies on a battery of enzymes able to modulate chromatin structure in a highly targeted and regulated manner.

Interaction of the pioneer transcription factor GATA3 with nucleosomes

Nature Communications, 2020
GATA 3 functions as a pioneer factor during cellular reprogramming. Here the authors delineate nucleosome positioning relative to GATA3 binding motifs and describe the structure of a GATA3–nucleosome complex; providing insight into how a pioneer factor ...

Proteomic interrogation of human chromatin. [PDF]

, 2011
Chromatin proteins provide a scaffold for DNA packaging and a basis for epigenetic regulation and genomic maintenance. Despite understanding its functional roles, mapping the chromatin proteome (i.e. the "Chromatome") is still a continuing process. Here,

Internal modifications in the CENP-A nucleosome modulate centromeric dynamics

Epigenetics & Chromatin, 2017
Background Posttranslational modifications of core histones are correlated with changes in transcriptional status, chromatin fiber folding, and nucleosome dynamics. However, within the centromere-specific histone H3 variant CENP-A, few modifications have

Repressive and non-repressive chromatin at native telomeres in Saccharomyces cerevisiae [PDF]

, 2009
Background In Saccharomyces cerevisiae genes that are located close to a telomere can become transcriptionally repressed by an epigenetic process known as telomere position effect.

Male Germline Chromatin [PDF]

, 2020
Spermatogenesis requires radical restructuring of germline chromatin at multiple stages, involving coordinated waves of DNA methylation/demethylation, histone modification, and the replacement and removal that occurs before, during, and after meiosis ...

Structural basis for the inhibition of HTLV-1 integration inferred from cryo-EM deltaretroviral intasome structures

Nature Communications, 2021
Human T-cell lymphotropic virus type 1 (HTLV-1) is an oncogenic deltaretrovirus. Here the authors provide structural characterization of the binding mechanism of novel integrase strand transfer inhibitor (INSTI) candidates to limit HTLV-1 infection.

Telomeric chromatin structure

Current Opinion in Structural Biology, 2022
Eukaryotic DNA is packaged into nucleosomes, which further condenses into chromosomes. The telomeres, which form the protective end-capping of chromosomes, play a pivotal role in ageing and cancer. Recently, significant advances have been made in understanding the nucleosomal and telomeric chromatin structure at the molecular level. In addition, recent

Job Opening for Nucleosome Mechanic: Flexibility Required

Cells, 2020
The nucleus has been studied for well over 100 years, and chromatin has been the intense focus of experiments for decades. In this review, we focus on an understudied aspect of chromatin biology, namely the chromatin fiber polymer’s mechanical ...
