Nucleosome thermodynamics, histone modifications, and histone chaperone function

The FASEB Journal, 2010
Genome accessibility is regulated to a large part by the posttranslational modification of histones (PTM). Surprisingly, and despite the fact that nucleosomes were first characterized over 35 years ago, very little is known about the free energy required to assemble and maintain ...

RNA‐binding protein RBMS1: A new target for cancer diagnosis and treatment

Precision Medical Sciences, EarlyView.
This schematic illustrates the diverse regulatory roles of RNA‐binding motif single‐stranded interacting protein 1 (RBMS1) across multiple human cancers. In breast cancer, RBMS1 stabilizes B4GALT1 mRNA to promote PD‐L1 glycosylation, modulating tumor immune escape and immunotherapy efficacy.

Mechanistic models of asymmetric hand-over-hand translocation and nucleosome navigation by CMG helicase

Nature Communications
Faithful replication of eukaryotic chromatin requires the CMG helicase to translocate directionally along single-stranded DNA (ssDNA) while unwinding double-stranded DNA (dsDNA) and navigating nucleosomes.

A long non-coding RNA is required for targeting centromeric protein A to the human centromere

eLife, 2014
The centromere is a specialized chromatin region marked by the histone H3 variant CENP-A. Although active centromeric transcription has been documented for over a decade, the role of centromeric transcription or transcripts has been elusive.

Recent Advances in Photocatalyst‐Driven Protein Labeling and Proximity Mapping

The Chemical Record, EarlyView.
Photocatalyst‐driven protein labeling and proximity mapping have rapidly advanced as powerful strategies for spatiotemporal control in complex biological environments. This review integrates recent developments across single‐electron transfer and energy transfer‐based mechanisms and highlights how catalyst design, reactive intermediates, and diffusion ...

Imaging the fate of histone Cse4 reveals de novo replacement in S phase and subsequent stable residence at centromeres

eLife, 2014
The budding yeast centromere contains Cse4, a specialized histone H3 variant. Fluorescence pulse-chase analysis of an internally tagged Cse4 reveals that it is replaced with newly synthesized molecules in S phase, remaining stably associated with ...

Resolving Endoplasmic Reticulum‐Protein Misfolding Restores Corticosteroid Sensitivity in Experimental Models of Severe Asthma

Allergy, EarlyView.
This study investigates the role of ER stress in steroid resistance in severe asthma. Results from advanced 3D models of human bronchial epithelial cells, steroid‐resistant severe asthma mouse models, and human severe asthma sputum samples show that treatment with ICS in combination with the ER stress inhibitor 4‐PBA significantly enhances steroid ...

USP52 acts as a deubiquitinase and promotes histone chaperone ASF1A stabilization

Nature Communications, 2018
Histone chaperone ASF1A is often dysregulated in cancers, however the regulation of its abundance is unclear. Here, the authors show that USP52 promotes ASF1A stability through deubiquitination while impairment of this stability reduces breast ...

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances

Andrology, EarlyView.
ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...
