Remodeling of RNA-Binding Proteome and RNA-mediated regulation as a new layer of control of sporulation Sporulation allows certain bacteria to survive extreme conditions for extended periods posing challenges to public health and food safety. Transcriptional level of regulation relying on σ factors has ...

🚨 New preprint! 🚨
We just dropped our latest work on RNA-binding proteins and sporulation in B. subtilis! Turns out, the RBP landscape gets a major remix during sporulation 👀. Check it out here 👉 www.biorxiv.org/content/10.1...

30S-seq redefines the bacterial Ribosome Binding Site The translation initiation step is rate limiting for the efficiency of gene expression in all organisms. However, the mechanism of ribosome recruitment to mRNA start sites strikingly differs between e...

I am thrilled to share this new preprint from our lab!
We find (>800!) 30S binding sites in hundreds of 5'UTRs, but also new dynamic steps of translation initiation.

The result of a collective effort by all the members of the Rougemaille lab and others, including @jessicaandreani.bsky.social
A work supported by @agencerecherche.bsky.social, @fondationarc.bsky.social, @cnrs.fr and @univparissaclay.bsky.social

Thrilled to see our story now out at @naturecomms.bsky.social
A shared adventure with Estelle Leroy and Mathieu Rougemaille @i2bcparissaclay.bsky.social, and with the precious help of the @palancadelab.bsky.social
Such a tiny RNA with such a wide range of functions

Happy to share our genetic toolkit designed to make your gene editing (life) easier, faster and very efficient!

Also suitable to build saturated chromosomal variant libraries using oligo-recombineering with extra short homology arms!

My main Ph.D project on the role of General Regulatory Factors in protecting promoters from ectopic and divergent transcription initiation is now available. So enthusiastic to finally see the result of this great adventure with @DomenicoLibri @LabLibri
