Thanks for sharing! Happy to see our work highlighted by @lcbm-epfl.bsky.social ⚡️: Electrostatics tune TF search and chromatin invasion. I appreciate my former colleagues for the discussions and help with troubleshooting throughout this work. Grateful as well to EPFL facilities for their support.

TFs search are governed by many parameters, what about electrostatic forces? @simsakong.bsky.social led a multi-scale study on Sox2 revealing how electrostatic interactions influence its search. In close collaboration with @davidsuter.bsky.social. Congratulations Sim 🎉 www.nature.com/articles/s41...

I’m excited to share that my PhD work is now published in @natcomms.nature.com! Big thanks to @davidsuter.bsky.social & @beatfierz.bsky.social for your guidance throughout this work. We show that electrostatic differences in disordered regions control TF search and chromatin invasion. More details👇

How do electrostatic forces impact TF search ? In joint effort with @beatfierz.bsky.social , tour-de-force from @simsakong.bsky.social who single-handedly combined in vitro SPT on DNA & chromatin, in cellulo SPT, ChIP-seq and ATAC-seq www.nature.com/articles/s41...

Impressions from the LCBM Xmas party.!Happy holidays!!! 🎄🎁🎅🏽

Exciting research update 🎉 How do eukaryotic TFs find target sites on the chromatinized genome? How does DNA state—naked or nucleosomal—shape their search strategy? We investigated how the charge of disordered regions flanking DBDs influences target search and pioneering activity. Check it out! 👇

A Site‐Specific Click Chemistry Approach to Di‐Ubiquitylate H1 Variants Reveals Position‐Dependent Stimulation of the DNA Repair Protein RNF168

We developed a click chemistry approach to di-ubiquitylate histone H1 at relevant DNA repair-associated positions (H1KxUb2) to probe its effect on the E3 ligase RNF168. We demonstrate that H1KxUb2 st...

Single-molecule analysis reveals the mechanism of chromatin ubiquitylation by variant PRC1 complexes

Chromatin regulation relies on "writer" enzymes that add post-translational modifications (PTMs) to histone proteins. Variant Polycomb repressive complex 1 (PRC1) exists as several subtypes, which are...

1/ Preprint haiku alert 🤓✍🏻 Cells walk a tightrope— proteins made and then destroyed, balance must be kept. Yet how is this done? A mystery in the cell, we set out to ask. Live imaging helps, plus models and omics, too— data tells the tale.
