Molecular mechanisms of biomolecular condensate formation in Drosophila melanogaster siRNA biogenesis Abstract. Biogenesis of small interfering RNAs (siRNA) in Drosophila melanogaster involves the processing of double-stranded RNA (dsRNA) by Dcr-2 with Loqs

New paper in collaboration with the Förstemann Lab & Boekhoven Lab is out! Combining #NMR & mutational analysis, we characterize the unique features of the #Ago2 IDR region which drives Ago2/RNA #condensate formation.

J'entends Aurore Bergé sur @franceinfo.fr expliquer que les gens sont contres la loi Duplomb parce qu'ils sont désinformés.
Désinformés par qui ? 14 sociétés savantes ? La ligue contre le cancer ? Le CNRS écologie environnement ?

Very happy to share our preprint on heavy metal associated (HMA) domain-containing rice proteins bound by the rice blast MAX effector AVR-Pia! 🌾

You designed binders for your favourite protein and wish there was a way to experimentally screen them within 24h w/ only a set of pipettes and a plate reader?

Triple Labeling Resolves a GPCR Intermediate State by Using Three-Color Single Molecule FRET The correlation of individual conformational changes in dynamic protein complexes remains challenging as most structural methods rely on averaged information over a large number of molecules. Single molecule FRET is a powerful tool for monitoring such conformational changes. When performed using three distinct probes, it enables the correlation of domain movements by providing up to three simultaneous distance measurements with high temporal resolution. Nevertheless, a major challenge lies in the site-specific attachment of three probes to unique positions within the target protein. Here, we propose an orthogonal triple-labeling strategy that is not compromised by native, reactive amino acid functionalities. It combines genetic code expansion and bioorthogonal labeling of two different noncanonical amino acids with an enzymatic self-labeling SNAP tag. We demonstrate its application by establishment of a 3-color sensor on the human metabotropic glutamate receptor 2, a dimeric, multidomain G protein-coupled neuroreceptor, and describe a previously unknown conformational intermediate state using 3-color single molecule FRET.

Our new study is out !
We introduce a triple labeling strategy (2 non canonical Amino Acids + 2 click chemistries and 1 SNAP-tag) to triple label a G-protein coupled receptor.

Schematic of Hsp90's conformational cycle and the effect of Sgt1 that stabilizes the client's complex and prevents Aha1 binding.

New preprint is out! We've looked at the interactions of Sgt1 with Hsp90 in yeast and found some surprising results! We've also shown that in the presence of clients, Sgt1 prevents aha1 binding on Hsp90 and thus increases the substrate's dwell time. #NMR #chaperone

French researcher, going to a conference in Houston, was forbidden entry to US; his work and personal electronics were both confiscated.

Why? Because a “random search” of his cell phone revealed a negative personal opinion on Trump and the Trump administration. www.lemonde.fr/internationa...

I think it's important to reach out to your own community and explain what the funding cuts mean in practice.
