Wow! Amazing stuff from @matteoall.bsky.social. Congratulations to all the authors involved.

It’s out! Using cryo-ET in Dicty cells, we take a fresh in situ look at vaults. Surprisingly, we uncover vaults associated with ER and NE membranes, and find that many vaults enclose ribosomes in defined orientations, opening new avenues to their cellular function! www.biorxiv.org/lookup/conte...

Check out our new work! In collaboration with @moitrayee-lab.bsky.social lab at Yale!

I would be particularly keen to chat with #cryoET experts who would be interested in working on exciting new models of neurodegeneration, but the brief is wide open and could involve tau filament formation with recombinant protein, in cell cultures or in mice.

Thrilled to share my recent work from the Pereira and Sherman Labs at @umlifesciences.bsky.social, out now in Communications Chemistry! We applied metabolic engineering, semi-synthesis, and biocatalysis to expand access to the antimalarial natural product premarineosin A. I suggest you check it out!

Thrilled to share that the final piece of my PhD work is now on bioRxiv! biorxiv.org/content/10.1... With support from @nvidia and the @NSF, we used AlphaFold to screen 1.6M+ protein pairs, revealing thousands of potential novel PPIs. All data can be viewed at predictomes.org/hp

Just published! We share an open-source workflow to measure membrane thickness from tomograms, including a tutorial with 3D visualizations. We analyze thickness variations across organelles and reflect on where to define a membrane boundary. @becklab.bsky.social #teamtomo rupress.org/jcb/article/...

Happy to share this satellite story. Structure of tau filaments from the amygdala of patients with mixed pathologies #Alzheimer’s and LATE. Strikingly, none of the patients had documented head injury or trauma but tau adopts a CTE-fold Preprint: www.biorxiv.org/content/10.1...

Nothing short of spectacular!🤩

Very excited that my final postdoctoral work is now online in Cell @cellpress.bsky.social. www.sciencedirect.com/science/arti... Using 16 (!) cryo-EM structures, we uncovered how the three proteins coronin, cofilin and AIP1 work together to rapidly disassemble actin filaments.

Great discussion here!

New PrePrint from the Vecchiarelli and Mosalaganti (@shyamalm.bsky.social) labs! 🧵 Collaboration with the Giessen and Pi labs Congratulations to co-first authors Y Hoang (@hoanghamyy.bsky.social) and Pankaj Jadhav! www.biorxiv.org/content/10.1...

Ever wondered how to position organelles in bacteria? Wonder no more! Happy to have contributed to this fantastic story from @cellforganized.bsky.social' lab. The avenues this opens in the synthetic biology space are enormous! Movie: Carboxysomes positioned in E. coli! Preprint: shorturl.at/D6xVg

If you are thinking about the future of structural biology, we are too! Our two cents (Jürgen Plitzko and I) just got published online here: authors.elsevier.com/sd/article/S...

HPV is the most common STI. Revisiting the infection pathways, we discover that, contrary to the accepted model of trafficking, HPV stays intact and infectious in host cell lysosomes 🤯. Among other discoveries, we show that the intact virus is a cargo of COPI-coated pits!

Happy to have contributed to this amazing story by Hari!

Our new preprint: how photoprotection is spatially coordinated with energy metabolism. Photosystem I is major source of radicals. We report EM structure of PSI in complex with superoxide dismutase SOD: direct link between energy conversion & oxidative stress defence www.biorxiv.org/content/10.1...

We are happy to release LocScale2.0: a tool for context-aware, confidence-weighted cryoEM map optimisation. Taking two half maps as input, LcoScale-2.0 produces feature-enhanced maps along with a robust confidence score that guides objective map interpretation. cryotud.github.io/locscale/

We’ve uncovered Asgard chromatin structures formed by a Hodarchaeal histone : closed hypernucleosome conserved in archaea and an open form resembling the H3-H4 eukaryotic octasome. Fantastic work by @harshranawat.bsky.social! www.biorxiv.org/content/10.1... #Chromatin #Asgard #Archaea #cryoEM

Happy to have contributed to this amazing story from @caroleparentlab.bsky.social at the @umlifesciences.bsky.social www.nature.com/articles/s41... Congrats to all involved.

Problem cryo-ET structure alert. A recent paper by Lange et al. in @natcellbio.nature.com (tinyurl.com/38s6a4dn) reported an unusual-looking model of the prohibitin complex in situ. We asked: how was this structure generated? Our reanalysis offers an explanation: tinyurl.com/mszdtwxx 🧵

*Deadline extended* Applications for this year's #CryoEM Data Processing Workshop are due March 27! Don't miss this chance to learn about various approaches to deal with conformational/compositional heterogeneity. myumi.ch/lsi-cryo-2025 @jbquerido.bsky.social @shyamalm.bsky.social

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/... @wehi-research.bsky.social @komanderlab.bsky.social

Happy to share this work from my group on the endolysosomal/PM resident 2 pore potassium channel with roles in #inflammation We determine the structure and show that it is pH independent, voltage-gated using high-throughout whole cell electrophysiology assay. www.biorxiv.org/content/10.1...
