Nucleosome assembly and disassembly pathways in vitro

Structural fluctuations of nucleosomes modulate the access to internal DNA in eukaryotic cells; clearly characterisation of this fundamental process is crucial to understanding gene regulation. Here we apply PhAST (Photochemical Analysis of…

Different Pathways Conferring Integrase Strand-Transfer Inhibitors Resistance

Integrase Strand Transfer Inhibitors (INSTIs) are currently used as the most effective therapy in the treatment of human immunodeficiency virus (HIV) infections. Raltegravir (RAL) and Elvitegravir (EVG), the first generation of INSTIs used…

Differential activation of human neutrophils by SARS-CoV-2 variants of concern

The emerging SARS-CoV-2 virus has affected the entire world with over 600 million confirmed cases and 6.5 million deaths as of September 2022. Since the beginning of the pandemic, several variants of SARS-CoV-2 have emerged, with different…

Cryo–electron microscopy unveils unique structural features of the human Kir2.1 channel

We present the first structure of the human Kir2.1 channel containing both transmembrane domain (TMD) and cytoplasmic domain (CTD). Kir2.1 channels are strongly inward-rectifying potassium channels that play a key role in maintaining resting…

The convergence of head-on DNA unwinding forks induces helicase oligomerization and activity transition

Significance Bloom syndrome helicase (BLM) is a multifunctional helicase that primarily catalyzes the separation of two single strands of DNA. Here, using a single-molecule optical tweezers approach combined with confocal microscopy, we monitored…

The Autophagy Receptor TAX1BP1 ( T6BP ) improves antigen presentation by MHC‐II molecules

CD4 + T lymphocytes play a major role in the establishment and maintenance of immunity. They are activated by antigenic peptides derived from extracellular or newly synthesized (endogenous) proteins presented by the MHC-II molecules. The pathways…

Bloom Syndrome Helicase Compresses Single‐Stranded DNA into Phase‐Separated Condensates

Bloom syndrome protein (BLM) is a conserved RecQ family helicase involved in the maintenance of genome stability. BLM has been widely recognized as a genome "caretaker" that processes structured DNA. In contrast, our knowledge of how BLM behaves on…
