Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Diversity of chromatin condensation patterns, nuclear reorganization, evolution and phylogenetic distribution of sperm nuclear basic proteins in fish

, 2021
One of the most astonishing examples of chromatin remodelling occurs during the maturation of male germ cells, where changes in protein structure, as well as chromatin compaction, take place.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Bactericidal activity of mammalian histones is caused by large membrane pore formation

Cell Reports
Summary: Histones have an important role in eukaryotic innate immunity, wherein histones co-localize with antimicrobial peptides (AMPs). The mechanism of histone cooperation with AMPs and the extent to which histones form pores both remain a mystery ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Distinctive Nuclear Features of Dinoflagellates with A Particular Focus on Histone and Histone-Replacement Proteins

Microorganisms, 2018
Dinoflagellates are important eukaryotic microorganisms that play critical roles as producers and grazers, and cause harmful algal blooms. The unusual nuclei of dinoflagellates “dinokaryon„ have led researchers to investigate their enigmatic ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Why are histones dynamic?

, 2015
Afin de pouvoir être contenu dans le noyau des cellules eucaryotes, l'ADN doit être compacté en un ensemble très structuré. L'ADN eucaryote est généralement associé à des protéines, principalement à des histones, pour former cette structure très compact ...

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Bacterial and Archaeal Histones Structure DNA Differently

, 2023
Histones are small DNA binding proteins that structure DNA. Eukaryotes use well conserved histones to wrap DNA into nucleosomes; discrete packages used to regulate gene expression and structure genomes. Most archaea also encode histones, such as HMfB and
