🧐 What if metabolic defects are not just a consequence of inflammatory disease - but actively contribute to it? Inflammation and metabolism are deeply intertwined, but the molecular links remain unclear. Our new paper in Cell Death & Differentiation uncovers one. 🧵👇 nature.com/articles/s41...

Really happy to see this one out: www.sciencedirect.com/science/arti... Alibek's drive & great coll w/ friends @gekaragoz.bsky.social & E. Hallacli resulted in a cool story that starts with our beloved #Marchantia and ends with iPSC-derived neurons 🤩🤪 A short 🧵

I have multiple positions available to join my lab from this summer: #postdoc, #student and #technician. Adverts to follow but see www.saurinlab.com for further details. #senescence, #mitosis, #cellcycle, #phosphorylation are the key areas. Email me if interested.

Super new paper from @ubch-alice.bsky.social and Danny Huang @cruk-si.bsky.social – a great deal of hard work and development behind this story. From a technical perspective, this reads as a primer for tapping 'unconventional' E3s. Very well done Alice and team!

Excited to share our work into ubiquitin E1-E2 specificity mechanisms. CryoEM visualising #ubiquitin transfer,biochemistry,evolution @labhofmann.bsky.social & tissue expression analyses @psarkies.bsky.social Big thanks to the team,reviewers & handling editor @dimitristypas.bsky.social rdcu.be/eTRdR

We’re thrilled to onboard Alice Wicks @ubch-alice.bsky.social in the lab this week. Alice trained with Danny Huang @cruk-si.bsky.social and has developed exciting new ideas for co-opting E3s for targeted degradation. Welcome to the team, Alice.

We’ve made some new tools to manipulate N-recognins. Check them out in our preprint. www.biorxiv.org/content/10.1...

Pre-print: our description of RZ affiliate ZNFX1 is now online. On binding viral RNA, ZNFX1 generates parallel Ub currents, coordinating Ub-dependent RNA silencing and aggregate resolution. Huge effort from first authors Dan Squair and @eilidhrivers.bsky.social www.biorxiv.org/content/10.1...

So excited to see our newest study out in print! Led by the brilliant @jgezelle.bsky.social and @sophiekorn.bsky.social, we discovered how viruses from highly divergent families converge on a shared RNA structure mechanism to inhibit cellular nucleases. #RNAsky #LoveVirology

Glad to share the final version of our story about the UBR4 complex, an E4 ligase protein quality control hub @science.org. Now with more cryo-EM structures and a deeper dive into substrate recognition, especially escaped mitochondrial proteins @clausenlab.bsky.social www.science.org/doi/10.1126/...

Happy to share our work on the structure and function of the unusual E3 ligase ZNFX1 @cp-cell.bsky.social. It uses a nucleic acid-activated transthiolation mechanism, ubiquitinating and clustering RNA to protect cells in an immune response. @clausenlab.bsky.social www.cell.com/cell/fulltex...
