Proud to share the yeast telomerase structure, led by the talented @hongmiaohu.bsky.social in collaboration with the Wellinger and Chartrand labs. Discovered 37 years ago and took us nearly 7 years but totally worth the wait 😍. www.science.org/doi/10.1126/... www.youtube.com/watch?v=gFE4...

Automatic screening of cryo-EM grids using EPU is fast and efficient, but reviewing the generated data & picking the best areas for data collection can be slow and cumbersome. We made a little tool that makes this process more streamlined and enjoyable: github.com/mvorlander/E... 1/4

How does the cell tune p97/Cdc48 activity for different substrates? Study suggests different adaptor combinations function as molecular accelerators of protein clearance. www.science.org/doi/10.1126/...

More evidence that LUBAC has functions beyond inflammation: Our study shows that LUBAC regulates AMPK signalling to control metabolic adaptation, autophagy, and cell death. This might explain the metabolic problems observed in LUBAC deficiency and ORAS patients. www.nature.com/articles/s41...

FAF1 and FAF2 enhance human p97-UFD1-NPL4 complex unfoldase activity enabling rational design of p97 activators https://www.biorxiv.org/content/10.64898/2026.02.24.707758v1

This project started with confusion 🤔 www.nature.com/articles/s41... Loss of LUBAC or OTULIN causes severe inflammatory disease. But patients also show clear metabolic defects. Neither LUBAC nor OTULIN had been linked to metabolic regulation. So where do these metabolic manifestations come from?

🧐 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...
