Frank Nijpels from VitriMatics paid us a visit today. Not only did he repair our broken VitroBot Mark IV and returned it in person, he also brought some extremely cool tools ❄️ for reliable cryo-EM grid freezing 🔬. Check out the VitriClip and the SupraBlot at vitrimatics.com. #cryoEM #cryoET

New preprint! 👀RNAse activity has to be tightly regulated.✂️🧬Here, we present the dynamic architecture of the conserved Rixosome complex – a major player in ribosome maturation and heterochromatin maintenance. Our results give insights into its mode of activation.👇 #cryoEM #Ribosome #RNA

📰Happy to share our preprint.🥳Here we investigate🔬, the essential role of the conserved RNA helicase Drs1. We show that its engagement and activity license timely incorporation of 25S rRNA domain III into maturing nucleolar pre-60S subunits.👇 doi.org/10.64898/2026.09.05.749353 #cryoEM #ribosome #RNA

Preprint alert: a helicase watching the ribosomal A-site 👀🧬 Our cryo-EM structure reveals how yeast Dhx29 senses mRNA hairpins forming in the A-site and positions its helicase at the mRNA entry channel to resolve them during translation elongation: doi.org/10.64898/202... #cryoEM #ribosome #RNA

It's finally out now in @natcomms.nature.com! We used cryo-EM + simulations to watch the Na⁺/H⁺ antiporter NhaA in action across a wide range of pH—and uncover how pH, Na⁺ binding, and structural changes are coupled. Read here 🔗 www.nature.com/articles/s41...

Proud to share our latest preprint! 🥳 Using a multidisciplinary approach, we uncover a dual function of the snR37 H/ACA snoRNP - combining pseudouridylation with ribosome chaperone activity within a single RNP.🔬🧬 Challenging the traditional view of snoRNP function. 👇 #cryoEM #ribosome #RNA #snoRNA

Glad to be part of this great work from @beckmannlab.bsky.social, led by @guan316.bsky.social and @timodenk.bsky.social, exploring the mechanics of co-translational acetylation of histones by NAA40.

How are histones acetylated as they emerge from the ribosome? We show that NAA40 cooperates with the NAC complex to enable co-translational acetylation of H2A/H4, revealing NAC as a coordinator of nascent protein modification. Read more about our collaboration with @kirmizislab.bsky.social #cryoEM

We are excited to share our collab with @kedrov-lab.bsky.social! Using Cryo-EM❄️ on an amazing sample, we found that YidC is recruited to the back of SecYEG during late-stage substrate insertion —supporting that the "back-of-Sec" route observed in eukaryotes also exists in bacteria 🦠. Check it out👇👇👇

How does an unusual heptameric AAA-ATPase translocate fully-folded Rieske protein across the inner mitochondrial membrane? Cryo-EM & functional data by Roland Beckmann and coworkers show how Bcs1 alternates between different states during its translocation activity. www.embopress.org/doi/full/10....

We are happy to share that our snR30 story is finally out in @natureportfolio.nature.com 🥳 We report the first structure of a H/ACA snoRNP acting in ribosome synthesis thereby providing a detailed structural and biochemical view of the snR30 snoRNP guiding local 18S rRNA subdomain folding. 👇👇👇
