Travel’s got me wiped, but catching up with @colindascheele.bsky.social, @pierresantucci.bsky.social & @olivierduss.bsky.social at #FEBS2025 made it totally worth it. Huge thanks to Pelin Telkoparan and Dilek Cevik for the wonderful hospitality—what a time in Istanbul!

Excited to share our new @science.org paper! Led by postdocs Ruchao Peng and Xin Xu, we used cryo-EM/ET to reveal the influenza ribonucleoprotein complex structure and its strand-sliding mechanism for RNA synthesis, paving the way for new antivirals.

Molecular basis of influenza ribonucleoprotein complex assembly and processive RNA synthesis

Influenza viruses replicate and transcribe their genome in the context of a conserved ribonucleoprotein (RNP) complex. By integrating cryo–electron microscopy single-particle analysis and cryo–electro...

The timeline of co-transcriptional #mRNA processing and #modification may have to be revised: cleavage, termination, and #m6A deposition may occur earlier than most #splicing! Potential textbook changing study in bioRxiv by edueyras.bsky.social & Rippei Hayashi labs!

Single-molecule multimodal timing of in vivo mRNA synthesis

mRNA synthesis requires extensive pre-mRNA maturation, the organisation of which remains unclear. Here, we directly sequence pre-mRNA without metabolic labelling or amplification to resolve transcript...

Ever wondered how several individual RBPs cooperate to repress translation?

Lead by @marcopayr.bsky.social and in great collaboration with @hennig-lab.bsky.social, we simultaneously tracked the binding of several proteins to single mRNA molecules in real-time!

The RNA helicase HrpA rescues collided ribosomes in E. coli

Antibiotics that inhibit ribosomes lead to collisions on mRNAs when upstream ribosomes catch up with stalled ones. Campbell et al. show that the HrpA protein in E. coli senses ribosome collisions and removes the stalled ribosome, helping cells survive in…
