⚡Preprint alert⚡ So proud of @amohamed98.bsky.social! Abdallah determined the cryo-EM structure of BRD4 bound to the kinase P-TEFb, defining the molecular basis of this key transcription interaction — and revealing that BRD4 and AFF4 binding are mutually exclusive to P-TEFb. Lots more inside 👇

Abdallah Mohamed@amohamed98.bsky.social

New preprint: in the last bit of my graduate work in the @voslab.org, we describe the mechanism for how BRD4 engages with P-TEFb in the context of regulating early RNA Pol II elongation. Read more here: www.biorxiv.org/content/10.6...

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...

⚡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

Big thanks to our lab and our collaborators from the lab of Andreas Mayer, Annkatrin Bressin and Zhihao Shao at @molgen.mpg.de and the Institute of RNA Biology and Genomics at the Medical University of Innsbruck

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...

nature.comC-terminal amides mark proteins for degradation via SCF–FBXO31 - NatureSCF–FBXO31 scans proteins for C-terminal amidation and marks them for subsequent proteasomal degradation.

Only two days left to apply to the joint Epigenetics and Chromatin Architecture & Transcription Regulation meeting 👇 We're looking forward to seeing you in Banff!

Keystone Symposia@keystonesymposia.bsky.social

The ⏰ is ticking to submit your abstract or scholarship application for a chance to present a short talk at our Epigenetics meeting. Make sure to send them in by 11:59 PM MST on January 9th! keysym.us/KSEpigenetic... #KSEpigenetics25 #epigenetics #humandevelopment #developmentalbiology

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

You are up to date.
