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...

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.
