Deltaviruses spread through a viral Trojan Horse Hepatitis D-like satellite viruses, known as deltaviruses, have been recently discovered in a wide range of animals. These viruses are thought to expr…

The Trojan Horse is real, and it’s microscopic! 🐴🦠
Our paper is out today in @cellcellpress.bsky.social!
We discovered that deltaviruses physically hide INSIDE helper viruses to sneak into new cells. And to prove it, we had to image them from every angle. 🧵👇

ps – slightly biased - i really like this year’s poster, highlighting the Dark Side of ubiquitin biology – fantastic art by the one and only @philippdexheimer.bsky.social – many thanks, philipp!

Ubiquitin & Friends Fiesta in Vienna, 29-30 April 2026.
Great speakers, small size, a friendly community, perfect for early-career researchers to connect with fellow ubiquitin enthusiasts. Sign up at www.protein-degradation.org/symposium/ and submit abstracts for talks and awards.

big congratulations, leo. exciting ub times ahead 🥳

Image of FAF2's predicted helical domain interacting with the UFD1 UT3 domain. Next to this are similar images showing the predicted binding of de novo designed protein binders to the same region. Above is a sequence alignment indicating the key residues involved in the interaction.

Screening p97 cofactors, @prithadg.bsky.social identified FAF2 as the strongest activator of the p97-UFD1-NPL4 complex. Leveraging her mechanistic descoveries, we designed 𝘥𝘦 𝘯𝘰𝘷𝘰 binders that could also enhance p97 substrate unfolding.

Our latest cotranslational folding story is now published @cp-molcell.bsky.social. Really cool (I think) new ideas about how exactly the ribosome directs folding and assembly to make sure complicated proteins mature efficiently in cells.

Have a look at our new structure of co translational folding in yeast. This is collaborative work initialized by the Rospert lab from the @uni-freiburg.de. Structural work has been done by the amazing @lgrundmann.bsky.social Stay tuned for the next ribosome paper from him, following very soon.

New preprint!
Led by @sarahgersing.bsky.social we map how 7,500+ variants in glucokinase (GCK) affect binding to GKRP and disentangle this from stability.
