#ESCRT-III
Happy to share our paper’s final version on the evolution, structure, and membrane binding / remodeling of Asgard ESCRT-III proteins! And my first 🦋 post! www.science.org/doi/10.1126/...
Asgard archaea reveal the conserved principles of ESCRT-III membrane remodeling
Asgard archaea have two ESCRT-III subunits with the conserved traits that drive stepwise membrane remodeling in eukaryotes.

Very glad to see our story on the choreography of #ESCRT proteins in #archaeal cell division finally published in mBio - Junfeng Liu et al "A relay race of ESCRT-III paralogs drives cell division in a hyperthermophilic archaeon" journals.asm.org/doi/10.1128/...

2470m down - tracking the bottom. The sediment is flat with large spirals drawn by worms in the mud. Anyone thinking Escrt-III?

Hot off the press, first PI paper 🎉. Reporting a novel protein (VIA1) involved in thylakoid membrane biogenesis. VIA1 (similar to ESCRT-II) and bind to chloroplast ESCRT-III (VIPP1). Showing a direct role of VIPP1 in thylakoid biogenesis.

New research on ancient Asgard archaeal ESCRT-III proteins reveals evolutionary secrets of membrane remodelling.
Diorge Souza, Javier Espadas and Sami Chaaban, investigated the ESCRT-III proteins with Buzz Baum and Aurelien Roux.

New preprint from the lab!!🎉
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?

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!

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...

Now out in NSMB for those who missed our biorxiv back in 2023.. bacterial ESCRT-III-like #Vipp1 forms dynamic spiral filaments on membrane! Spirals are springs that drive 3D ring formation in the spiral centre! 😵‍💫 wonderful collaboration with Adai Colom’s lab and @rouxlab.bsky.social

So, we all know that VIPP1 (the Very Important Protein in Plants) is the "photosynthetic ESCRT-III", required for the biogenesis and maintenance of light-harvesting thylakoids. But what about ESCRT-II, you say? ...Meet VIA1! Congrats @mayankdu.bsky.social on your lab's first paper! #PlantScience 🧪 🌾

Recently out! An awesome commentary on our (and others!) bacterial ESCRT-III work rdcu.be/ei98N - big thanks to John McCullough and Wes Sundquist for this. And of course big shout out to @natsmb.nature.com for the tasty cover!

ESCRTs are repurposed when missegregated DNA persist during nuclear envelope reformation, at this point ESCRT-III binds this DNA and mounts the NoCut response to protect the genome

Looking forward to sharing our latest work on the ESCRT-III complex in Asgard archaea!
Hope to see many of you online!
#membrane seminars are back this week with @javierespadas.bsky.social from the @rouxlab.bsky.social and Chris Burd from @yalecellbiology.bsky.social! Looking forward to seeing everyone online!

ESCRT-III is an ancient complex, present in Archaea, with only two proteins and all membrane remodelling functions. Great work by @javierespadas.bsky.social, @diorgeps.bsky.social, @sami-c.bsky.social, thanks to the @buzzbaum.bsky.social lab! Drawing by Julie Polge.

In a new publication, Team Harper found that α-synuclein fibrils cause ESCRT-III loss through “collateral degradation,” weakening endolysosomes and promoting further aggregation🔬

Javier has done beautiful work (following on from the study he did with Diorge Souza), showing how Asgard Escrt-III likely cut membranes. The answer: with Hofund.
