Do you want to label the nuclear envelope? Do you work on a non-model species? Try Concanavalin A! We tested ConA on various species across the eukaryotic tree and find it is a very useful ExM-compatible marker for the NE and ER. Read all about it in our preprint: www.biorxiv.org/content/10.6...

Check out our preprint on the structural mechanisms of how LEM2 and ESCRTs seal the nuclear envelope. Awesome collaboration with @karenpalacior.bsky.social who brought my structures to life 💃🔬❄️🌀 @hummerlab.bsky.social www.biorxiv.org/content/10.6...

💡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...

Are the lipids associated with static protein structures there as long-lived ligands or an effect of preferential solvation? This computational-experimental framework shows the way! #lipidtime #compchem www.nature.com/articles/s41...

Molecular basis for the regulation of membrane proteins through preferential lipid solvation - Nature Chemical Biology

Static protein structures can capture the association of lipids, but it is unclear whether the association is due to lipids acting as long-lived ligands or the solvation of preferred lipids around the protein. A computational-experimental framework has now shown that for the protein CLC-ec1, it is the change in lipid solvation energies that drives dimerization, with preferred lipids around the protein modulating this driving force.
