Lipids build the membranes of all cells, but identifying their precise functions is extremely challenging. Here’s our attempt to change that: How to find and understand lipid-protein interactions, by Katelyn Cook & company. www.biorxiv.org/content/10.6...

Very happy to see this #MechanoGolgi story out (and in full open access, thanks to @upf.edu). Thanks a lot to everyone who contributed and helped make this possible, and, hopefully, more to come! rupress.org/jcb/article/...

🧵 I've been meaning to write a #Skytorial on our recently posted prepring in which we show evidence that the Golgi 🥞 is a mechanoresponsive organelle. Extracellular mechanical forces also tune Golgi export capacity! 👉 www.biorxiv.org/content/10.1...

💡New Preprint! How does a cell control which way a membrane bends? ESCRT-III has the remarkable ability to reshape membranes and drive reverse-topology fission, yet a fundamental question has remained: what determines the direction of membrane remodeling? www.biorxiv.org/content/10.6...

Direction of ESCRT-III-dependent membrane bending emerges from bilayer asymmetry

In cells, ESCRT-III is unique in mediating fission of membrane necks from inside, a process called reverse-topology fission. Yet, in vitro, the complex primarily assembles outside membrane necks and m...

ESCRT-III assembles around mis-segregated DNA to protect genome stability - Nature Structural & Molecular Biology

The authors show that persistent ultrafine DNA bridges become coated by membranes and the ESCRT-III proteins CHMP1B and IST1, which protect the genome within from damage.

Do we grow wiser as we age? I spent 15+ years chasing glam journals, wasting time and energy (and frustrating my team and co-authors). I don’t want to wake up at 70 and realize my life went into convincing a few editors my work was trendy enough. Enough. I’ll try to be smarter.

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. #Autophagy #Tau #Proteostasis Out now 👇 www.biorxiv.org/content/10.6...
