Towards community-driven visual proteomics! Excited to finally share this large-scale curated & annotated dataset of 1829 high-quality #cryoET tomograms of the little green alga that just keeps giving— Chlamydomonas! 🧪🧶🧬🌾🌊🌍

Hellooooo beautiful!😍 #CryoEM #ArchaeaSky 🧪

Out in Science Advances: Our #cryoEM structure of HFTV1, a virus infecting the halophile #archaea. *First full atomic structure (containing all structural proteins) of any tailed virus!* Congrats and thanks to all co-authors and our fantastic collaborators! www.science.org/doi/10.1126/...
Cryo-EM resolves the structure of the archaeal dsDNA virus HFTV1 from head to tail
This structure of an archaeal tailed virus (arTV) provides detailed insights into arTV assembly and infection mechanisms.

#TeamTomo ❄️🔬 meets #MassSpec Imaging 🧬🔬. Super cool, and great potential for EM grids with mixes of different cell types. For example -- environmental samples! @embltrec.bsky.social 🌍 🧪

Check out our new preprint on an integrated pipeline combining in situ #cryo-ET with MALDI #MSImaging for single-cell identification and classification from previously analysed EM-grids.

This is rad! It gets me excited for the potential with mixed environmental samples. Congrats to you, @andschwarz.bsky.social and the crew!

Delightful to finally meet you @edwardmarcotte.bsky.social and hear about your crazy cool science exploring the proteomes of all the diverse beasties on the planet to reconstruct LECA 🧪🌎. Now I see where Caitie gets it from 👨‍🔬👩‍🔬

Can they make eggs from male skin cells? Or sperm from female skin cells? Now that would be interesting….

I think it has something to do with conservative lawmakers taking aim at liberal-leaning social media. See this announcement that my friend got. Did you get something similar? X is not affected by this law, and that place is swarming with misinformation and porn bots. No free speech = Hot Garbage 🔥🗑️

Time for a thread!🧵 How different is the molecular organization of thylakoids in “higher” plants🌱? To find out, we teamed up with @profmattjohnson.bsky.social to dive into spinach chloroplasts with #CryoET ❄️🔬. Curious? ..Read on!

The case for studying proteins inside the cell 😉

But there’s a curious loose end to this story. Scientists have been looking at PSII organization in thylakoids for over 50 years (including some really stunning freeze fracture 🔬😍). Sometimes PSII looks randomly oriented, and other times it forms extended 2D crystalline arrays in the membrane 💠

Love it! 🧪🤓 Ya know, thylakoids can also play this paracrystalline lattice game. In plants, they emerge from the prolamellar body during de-etiolation 🟡➡️🟢

An interesting parallel: Rod outer-segment disk membranes are highly packed with a membrane protein (rhodopsin) 👁️, similar to the stacked domains of thylakoids (PSII-LHCII) 🌱. And isolation of disk membranes may cause rhodopsin to crystallize into 2D arrays 💠

Thanks Marcel! But don’t you mean the prettiest membranes on Earth? 😉. Golgi tried hard…. but thylakoids are the best 🌱🏆

This study completes a trilogy of thylakoid papers in @elife.bsky.social, one every 5 years⏳⌛

Part 1 was my first #CryoET paper: elifesciences.org/articles/04889

Part 2 was my first paper with @wojwie.bsky.social: elifesciences.org/articles/53740

Time flies... so let's start working on Part 4? 🤓🧪

So, PSII arrays seem to be an artifact of isolating thylakoid membranes. And yet… We still wonder if these beautiful (and likely more static) structures play some physiological role during stress or damage. @wojwie.bsky.social & I wrote a mini-review on this:
