A stress response can be a great starting point for discovering new biology! By following genes regulated during the chloroplast unfolded protein response, we’re discovering novel factors involved in chloroplast homeostasis. Here’s the first one we characterized: www.pnas.org/doi/10.1073/...

💡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...

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...

During #NeuronalDifferentiation, #organelles dramatically reorganize. #Microtubules are essential tracks for transport. But are they just highways, or can they instruct organelle behavior? Are tubulin modifications a regulatory code that guides organelle position or function? 1/9

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...
nature.com
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.
