Registration for this mechanisms of RNA Polymerase regulation meeting is Aug 2: u.osu.edu/mltermmeeting/

Your cryo-EM work deserves to be seen 🔬 Submit your poster or talk abstract for the annual New England cryo-EM symposium by July 15th. The meeting will be held September 8th at MIT. This is the place to be if you are doing structural biology in the Northeast! Register: cryoem.mit.edu/2026-ne-cryo...

(1/n) Very excited to share tri-lab collab (Mirny & Zechner) led by Harvey, Henrik & Jack: Q: How do enhancers & promoters interact in space (contact vs. action-at-a-distance) and time (stable vs. transient)? A: Transient E-P contact (~25-42 nm lasting ~10-20 sec): www.biorxiv.org/content/10.6...

⚡New preprint from the lab⚡: A key early checkpoint in gene expression is promoter proximal pausing of RNA polymerase II. For over 20 years, we as field have not been able to recreate pausing under realistic cellular conditions. @robertovn.bsky.social shows that ELOF1 is the missing piece.

🚨 New preprint: GATO-seq did it again! ELOF1 is the missing promoter-proximal factor that confers RNA Pol II resistance to TFIIF. Including ELOF1, DSIF, and NELF in GATO-seq reactions recapitulates promoter-proximal pausing in vitro at physiological conditions for the 1st time. tinyurl.com/ELOF1

The E3 ubiquitin ligase mechanism specifying target-directed microRNA degradation (TDMD) is now published! 🎉🍾 We, @bartellab.bsky.social and Schulman lab, describe how 2-RNA factors control protein degradation by recruiting an E3 ligase. @mpibiochem.bsky.social www.nature.com/articles/s41...

Preprint alert 🚨Happy to share my first Posdoc manuscript from the Vos lab @voslab.org. We introduce GATO-seq, a high-throughput, fully in vitro technique that maps RNA polymerases at base pair resolution over time. Using it, we found a new pause state of Pol II: sidetracking tinyurl.com/superpause

🚨New preprint! We built a cell-free genomics platform (GATO-seq) to probe transcriptional regulation and discovered a “super pause” sequence that triggers a new Pol II active-site conformation. Huge shout-out to @robertovn.bsky.social for pulling off this monster of a project. tinyurl.com/superpause

Please join Andreas Ladurner and me for the GRC Chromatin Structure and Function conference to be held near Barcelona Spain from May 31-June 5! We accepting abstracts for posters and talks. The meeting is preceded by an awesome GRS. Learn more in our video below and apply www.grc.org/chromatin-st...

🧪🧬New preprint We present cryo-EM structures of reconstituted CTCF–nucleosome complexes, showing CTCF dimerization drives nucleosome oligomerization into defined higher-order assemblies. Disrupting CTCF–CTCF interfaces in mESCs reduces looping and impairs differentiation. tinyurl.com/CTCF-nucleos...

🎉Super excited to share our story on how the substrate receptor FBXO31 functions as a quality control factor by recognizing amides. This has been an amazing collaboration between Bode lab and @jcornlab.bsky.social. Special shutout goes to @matthiasmuhar.bsky.social www.nature.com/articles/s41...

C-terminal amides mark proteins for degradation via SCF–FBXO31 - Nature

SCF–FBXO31 scans proteins for C-terminal amidation and marks them for subsequent proteasomal degradation.

Our collaborative AGO2 work with @bartellab.bsky.social is published! Abdallah and Peter used cryo-EM and biochemistry to determine the structure of AGO2 in a slicing competent conformation with a fully paired RNA. Read more about it here: tinyurl.com/AGO2-slicing

The structural basis for RNA slicing by human Argonaute2

Mohamed et al. report the cryoelectron microscopy structure of human AGO2 with fully paired guide RNA. Their analysis reveals the structural basis for the slicing activity that drives RNAi, showing that the slicing-competent conformation is achieved by domain movements and RNA-protein contacts distinct from those of conformational intermediates and prokaryotic homologs.

Our paper describing a novel DNA binding mode for MORC2 is published! Congratulations to Nika Fendler on her first, first author paper. This was an epic effort and revealed many new and unpredicted functions for MORC2. You can read about it here: tinyurl.com/MORC2-DNA

The short talk abstract deadline for the Keystone Interplay of Chromatin Architecture and Transcription Regulation meeting is coming up (Jan 9). The meeting is being held jointly with the Epigenetics in Development and Disease meeting. Join us in Banff for some awesome science. #KSChromatin25
