Happy to announce our most recent preprint: Stereoselectivity and plasticity of a common binding pocket in TRPM3, by cryo-EM and elecrophysiology. Great collaboration with the Voets, Vriens and CISTIM labs.

Happy to share the latest from the lab, led by Daniel Alvarez, in collaboration with @lizconibear.bsky.social‬. In this AA-MD tour-de-force, we delve deep into the mechanism and energetics of lipid uptake by bridge-like lipid transfer proteins, and we learn a few interesting things along the way...

We are excited to announce the first in-cell structure of a LINC complex within a native nuclear envelope at subnanometer resolution!! #In-cell cryo-ET + #atomistic MD simulations! @tomdendooven.bsky.social et al!!

How do nuclear membranes fuse during NPC assembly? We answer this question in our latest work, where we identify a new mechanism for membrane fusion… (1/13)

Excited to share our latest story in Nature. We developed a high-throughput cellular stretch system to look for genes regulating membrane rupture under tension, and found an amazing small protein called NINJ1 that weakens the membrane for rupture! H/T to Zozo, my 10-y.o. for her artist's impression😃

I’m thrilled to finally share this preprint! It contains a WOW Cryo-EM structure (likely one of the strongest protein fibers known to man 🤯), but we’ve also untangled its biological function: a novel type of virulence factor💀!

In our latest preprint we used cryoEM to solve the structure of A-ENA fibers and show that they are stabilized by 10 isopeptide bonds per monomer. A-ENA couples the spore to the cry-toxins, and in doing so increases the virulence of Bacillus thuringiensis: www.researchsquare.com/article/rs-6...

Here's our newest study: we reveal the molecular principles of neuronal excitation by glutamate, and how physiological temperatures influence this process.

Thrilled to share the structure of dimerised human PINK1 docked to an endogenous translocase array on the mitochondrial surface, composed of two TOM complexes, bridged by a VDAC2 dimer! Published today in Science www.science.org/doi/10.1126/...

Just because it's a homo-oligomer, don't assume it's symmetric! @benjabsnt.bsky.social & collaborators used cryo-EM to study the transthyretin (TTR) tetramer (55 kDa), shedding light on its misfolding pathways linked to amyloid disease. Now in peer-reviewed form: www.nature.com/articles/s41...

Protein production for cryoEM structure determination just got a lot cheaper - high resolution structure from half a plate of HEK cells with the "MIcro ISolation (MISO)" microfluidics-based approach. Congrats to the Brunner and Efremov labs in Brussels! www.biorxiv.org/content/10.1...

Cryo-EM structures of mammalian membrane proteins from a single cell culture dish?

Yes, Micro ISOlation (MISO) sample preparation makes it possible.

Happy to be part of this exciting story and wonderful collaboration with the Rouslan Efremov lab.
