Holy smoke. What ultimately happened???

I fucking hate proline so fucking much it's the worst amino acid it's so fucking stupid it's incapable of being fucking normal so it forms an ugly ass ring with itself with its own fucking nitrogen cuz it's a loser fucking amino acid I hate it so much I'd rather cut off my right tit than have to ever draw a mechanism with proline ever again

Remember that everyone you meet is fighting their own battle, sometimes with amino acids

Context-dependent translation inhibition as a cancer therapeutic modality - Nature Communications Robust protein synthesis by the ribosome is required for rapid cancer growth. Here authors present interdictors, small molecule inhibitors of protein synthesis with context-dependent activity that inh...

Incredibly proud of our small but mighty team at Interdict Bio as we bring the interdictor modality closer to the clinic! Check out our first publication that lays the foundation for context-dependent translation modulators as a therapeutic approach for cancer!

Happy birthday to one of my favourite haters, Charles Darwin

I am getting excited about teaching at this! I think we're going to do copick, membrain-seg, morphometrics, and surforama on my day!

Cryo-electron tomogram on a navy background with text: Cryo-ET Data Processing Workshop. June 7-11, 2026

Join us this summer for U-M's 2026 #CryoET Data Processing Workshop!
This four-day workshop will introduce participants to standard image processing packages and all aspects of cryo-ET data processing.

Caveolins are conserved (metazoan) proteins essential for forming membrane-derived vesicles called caveolae.

While evolutionarily distant caveolins have similar structures, we found they do not maintain caveolae-generating capabilities (movie).

What determines this? Check out our new preprint!

I've been working on Surface Morphometrics for a new version (coming soon), and made some significant (AI-assisted) performance improvements, especially in pycurv (20-50x!). If you've had technical issues or just felt like it was too slow, give it another try! #teamtomo github.com/GrotjahnLab/...

EMBL is deeply saddened by the passing of our Interim Director General Peer Bork, a pioneering scientist who left an indelible imprint on life science research in Europe and beyond.

We extend our deepest condolences to his family, friends, and colleagues.

Online today, the journal version of our ( @nanigrotjahn.bsky.social @attychang.bsky.social @mmedina300kv.bsky.social) manuscript from earlier this year describing membrane thickness measurement in cells with #teamtomo! rupress.org/jcb/article/...

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.

Metabolic engineering and late-stage functionalization expand the chemical space of the antimalarial premarineosin A - Communications Chemistry Premarineosin A, a potent and selective antimalarial natural product, is a promising yet underexplored scaffold due to its limited availability and synthetic complexity. Here, the authors employ metab...

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!

Proteome-wide in silico screening for human protein-protein interactions Protein-protein interactions (PPIs) drive virtually all biological processes, yet most PPIs have not been identified and even more remain structurally unresolved. We developed a two-step computational...

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/...

While tau adopts PHF/SF folds as expected in Alzheimer's, the CTE-fold might be a common occurrence in pathologies with TDP-43 aggregation. The exact molecular mechanisms that drive this remain to be investigated.

CTE-Type Tau Filaments in Alzheimer's Disease with Co-morbid LATE-NC Alzheimer's disease (AD), the most common neurodegenerative disease, is defined by β-amyloid plaques and tau neurofibrillary tangles. Tau filaments in AD adopt the Alzheimer's fold, which is distinct ...

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

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!
