Part of our cell-free mRNA translation work (plus a 3-year project killed by Rabbit reticulocyte lysate artefacts) discussed in a Nature Technology & tools feature. Thanks to Amber Dance for the nice discussion! www.nature.com/articles/d41...
We report a human cell-free translation screen that identified NT-2, a Fusarium mycotoxin that blocks human ribosomes. The surprise: NT-2 does binds the ribosome and pushes them into a dormant state. www.nature.com/articles/s42...
A very exciting NMD story 🤩Congratulations to the team!
How are faulty #RNA degraded? New mechanistic insight into NMD: 1️⃣SMG5 & SMG6 PIN domains form a composite endonuclease (cPIN) 2️⃣ SMG5 completes the SMG6 active site, enabling efficient mRNA cleavage Fantastic collaboration with @labconti.bsky.social 🙏 👉 www.nature.com/articles/s41... 1/n

Using "in extracto cryo-EM", we visualize ribosomes in mammalian lysates, including RRL. "Hibernating" ribosomes carry an extended set of proteins that protect functional centers. These include elongation factor eEF2, LARP1 implicated in mTOR signaling, eIF5A etc. www.biorxiv.org/content/10.1...

Exciting new #Zebrafish research from the #WeinsteinLab, led by Jong Park! “Specialized gas-exchange endothelium of the zebrafish gill” — www.biorxiv.org/content/10.6... Amazing to see red blood cells moving through the gills! Don’t forget to check out the supplemental movies ;-)
🚀 New preprint! We used a human cell-free translation screen (~28 000 compounds) to discover NT-2, a #Fusarium -derived #mycotoxin that blocks human ribosomes. #Cryo-EM at 1.72 Å reveals a link between chemical inhibition and ribosome dormancy. www.biorxiv.org/content/10.1...
This work was possible thanks with the Cryo-EM hub at the @ethz.ch and the BSF screening facility at the EPFL. @nccr-rna-disease.bsky.social @mcid-unibe.bsky.social

Kandersteg has been the hub for the swiss @nccr-rna-disease.bsky.social RNA for most of the last 9 years of workshops. Collaborations and friendships were made, posters were drugged on ice streets, and plans and dreams were made on frozen slopes. Those #RNA days in Kandersteg have left their mark.
