The accessory adapters FAF1, FAF2, and UBXN7 accelerate proteasomal degradation by increasing prior p97-mediated substrate unfolding A group of accessory adapters positions the p97 adapter Ufd1 to boost substrate unfolding and subsequent proteasomal degradation.

VCP/p97’s accessory adapters (FAF1, FAF2, UBXN7) boost unfolding and subsequent proteasomal degradation. #ubiquitin. Our paper is out now:

Why do pathological protein aggregates persist in cells and how can we overcome this?
In our new preprint, we show that Tau aggregates fail to initiate selective autophagy and that their autophagic degradation can be restored.

Molecular basis for cellular compartmentalization by an ancient membrane fission mechanism The emergence of cell compartmentalization depends on membrane fission to create the endomembrane compartments. In eukaryotes, membrane fission is commonly executed by ESCRT-III, a protein complex con...

New preprint from the lab!!πŸŽ‰
We show that Asgard archaea ESCRT-III proteins can trigger membrane fission and reveal its molecular mechanism, offering clues to how these cells may have built internal compartments. But do these organisms even have these compartments?

We have wondered what a complex archaeal cell might look like ever since 2014. It’s been a long road (and the journey is far from over), but it’s a good time to pause for breath and look. These Asgard archaeal cells are a surprise! And that is the joy of being a cell biologist.

Quiescent cells stay alive by eating less. They downregulate amino acid transporters to match reduced demand. When this brake fails -> cell death & disease.

Just out in @science.org: Together with the lab of @wilhelmpalm.bsky.social, we used sequential in-vitro/in-vivo CRISPR screens to decipher metabolic adaptations in tumors. We find that acidosis is a dominant factor that shapes energy metabolism and stress resilience. www.science.org/doi/10.1126/...
