Our latest work is out in Nature today! Using smFRET, we directly visualized recruitment of the eIF4F complex to the 5' cap of eukaryotic mRNAs and formation of an activated mRNA. Our findings reveal new and surprising roles for each eIF4F component. 1/3 www.nature.com/articles/s41...

First paper of our lab today @natureportfolio.bsky.social by Nussi!

We provide a real-time movie on how #transcription and #translation cooperate using #single-molecule FM: we find long-range #ribosome/ RNAP communication mediated by #RNA looping!

Meet Romain Linares, cryo-electron microscopy (cryo-EM) expert at EMBL Grenoble.

In this interview, he talks about his role in managing the cryo-EM platform to explore molecules at the atomic level and his passion for stargazing.

Very cool work on single mRNA visualisation inside cells!
We designed MS2 and PP7 binding coat proteins that are degraded in cells except when bound by their hairpin RNAs.

We did this crazy project where we tried to see if proteins could interact with their mirror image ligand. Seems impossible when proteins need to form 3D structures to interact. But what about if the interaction remains disordered???

Stereochemistry in the disorder–order continuum of protein interactions - Nature
Studies on protein–protein interactions using proteins containing d- or l-amino acids show that stereoselectivity of binding varies with the degree of disorder within the complex.

How long does an mRNA stay in the nucleus? How long does it stay in the cytoplasm? In an amazing collaboration with @landthalerm.bsky.social, we used metabolic labeling, cell fractionation and mathematical modeling to quantify mRNA flow through the cell. Finally out in MSB: doi.org/10.1038/s443...
