Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Cryo-EM structure of the deltaretroviral intasome in complex with the PP2A regulatory subunit B56γ
Nature Communications, 2020 Human T-cell lymphotropic virus type 1 (HTLV-1) is a pathogenic deltaretrovirus. Here the authors resolve the cryo-EM structure of the deltaretroviral intasome in complex with the human host PP2A regulatory subunit.

Open Biology, 2021 Histone H1s or the linker histones are a family of dynamic chromatin compacting proteins that are essential for higher-order chromatin organization. These highly positively charged proteins were previously thought to function solely as repressors of ...

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

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.

Cryo-EM structures of the BAF-Lamin A/C complex bound to nucleosomes
Nature CommunicationsBarrier-to-autointegration factor (BAF) associates with mitotic chromosomes and promotes nuclear envelope assembly by recruiting proteins, such as Lamins, required for the reconstruction of the nuclear envelope and lamina.

Contribution of smFRET to Chromatin Research
Biophysica, 2023 Chromatins are structural components of chromosomes and consist of DNA and histone proteins. The structure, dynamics, and function of chromatins are important in regulating genetic processes. Several different experimental and theoretical tools have been

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.

Essentiality of CENP-A Depends on Its Binding Mode to HJURP
Cell Reports, 2020 Summary: CENP-A incorporation is critical for centromere specification and is mediated by the chaperone HJURP. The CENP-A-targeting domain (CATD) of CENP-A specifically binds to HJURP, and this binding is conserved. However, the binding interface of CENP-
