Happy to see our latest work published in @jcb.org. Led by an excellent PhD student, Abir Elfarkouchi, and in collaboration with @francoizochsenbein.bsky.social and co-first author Arthur Vitard, we investigated the structural mechanism of CM1 domain autoinhibition rupress.org/jcb/article/...

Excited to share our new VIP in Angewandte Chemie! Can foldamers mimic extended protein surfaces? Our peptide-oligourea foldamers reproduce the histone H3-H4 interface on the histone chaperone ASF1, combining nanomolar affinity, stability & cell permeability. onlinelibrary.wiley.com/doi/10.1002/...

Downsizing the Histone H3–H4 Quaternary Structure Into Foldamer Mimetics Yields High‐Affinity and Cell‐Permeable Ligands of ASF1
We present a foldamer strategy to downsize the histone H3-H4 quaternary structure into high-affinity, medium-sized binders (∼2 kDa) for the histone chaperone ASF1. Our peptide-oligourea chimeras, des....

A pleasure to reconnect with the 3R community - Replication, Repair and Recombination - at the 16th 3R Meeting in La Grande-Motte, 18-21 May 2026. Thanks to all for the great science, discussions and atmosphere, and to our sponsors. See you in two years! #3RMeeting #ReplicationRepairRecombination

The 14th #NMR a tool for biology conference was a big success, thanks to the contributions of our 200 attendees from 18 countries, and 40% of students/postdocs. The future of NMR is in good hands. 🥰 Have a safe trip back home. See you @pasteur.fr on May 10-12, 2027 @brukercorporation.bsky.social

(2/2)Through integrative structural and functional analyses, we identified a large disordered segment of Rad52 that binds Rad51 and functions as an assembly chaperone. It prevents Rad51 oligomerization, facilitates filament formation, and protects filaments from destabilization by the helicase Srs2.

(1/2) Thrilled to share our findings on the assembly of the Rad51 recombinase filament in Saccharomyces cerevisiae. This work is the result of a wonderful collaboration with Eric Coïc's team at CEA Fontenay-aux-Roses and Angela Taddei's team at the Institut Curie. www.biorxiv.org/content/10.1...
