Edward Marcotte

Nobel Laureate Professor Sir John Gurdon dies aged 92 It is with great sadness that the University shares the news of the death of Professor Sir John Gurdon, founder of the Gurdon Institute.

So sad to hear the news - John truly was an inspiration to so many, and one of a kind.

So much fun to host @edwardmarcotte.bsky.social at the @biozentrum.unibas.ch and introduce him to the @cellarchlab.com, thanks for a wonderful Discovery Seminar!!

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 👨‍🔬👩‍🔬

It was a blast! Thanks to you all for hosting me. Nothing but amazing science all day!

EXCITING NEWS!! We're searching for a new professor colleague at the Biozentrum🇨🇭. Ideal candidates are exploring novel biological questions with structure, biophysics, or high-resolution imaging. 🧪 🧶🧬 🔬

The call closes Nov 3. Please get in touch if you would like more information. Come join us! 👩‍🔬🤓

I'm looking forward to it! Excited to hear about all the fun science going on

Love #protists? Then you'd love this! Beautiful collection of hand-drawn critters represented here at the Oxford-Japan symposium on ethological dynamics in diorama environments sites.google.com/view/oxford-... #ciliates #testateamoeba #diatoms

Meet the CAGE: a newly-discovered protein nanocapsule💊, conserved from bacteria to eukaryotes! Looks more like an eclair🍩 than a prezel🥨. This protein pastry now makes us wonder- what's the filling!? Huge congrats to the ever-amazing @computingcaitie.bsky.social, now at the @biozentrum.unibas.ch 🧪🧶🧬

I am excited to share our new preprint on the CAGE complex, a mysterious hollow protein complex that I first saw years ago while surveying Tetrahymena ciliary lysate www.biorxiv.org/content/10.1... #cilia #protistsonsky 🧬🧪

The #PRETZEL is out !!!
Okay the CAGE renamed now fine.

Congrats @computingcaitie.bsky.social and team!!

YAYYYY, Immune systems of choano !!!!
Beautiful to see how knowledge about bacterial immune systems illuminate immunology in diverse organisms with the always incredible biochemistry and structural approaches of @kranzuschlab.bsky.social.
Wonderful work @yao-li.bsky.social 👏

Super excited for the full data, especially to see which of the over 400 screened binders actually got us the third place 🥳
Shout-out to the organizers for this very cool competition!

🚨The Bits to Binders Competition has concluded!🧬

One year ago we gathered scientists from around the world to design and submit protein binders that cause immune cells to target and eliminate CD20+ tumors

Spoiler: They work!

Structures of dynamic interactors at native proteasomes by PhIX-MS and cryoelectron microscopy Proteasome function depends on a network of transient interactions that remain structurally and functionally unresolved. We developed PhIX-MS (Photo-induced In situ Crosslinking-Mass Spectrometry), a ...

We are excited to share our preprint describing DirectContacts2! Here we develop a machine learning model to discriminate between direct and indirect protein interactions. We use our model to construct a highly accurate wiring diagram of the human cell.

Scientists, please take a moment to comment on these plans to limit animal testing in drug regulation and biomedical research. Use whatever experience you have to make your comments specific to you. The law requires regulators take these comments into account, so it might help. Mine is attached.

This is great! Thank you. Can the SIB help to keep the CASP challenge running?

We will be hosting a mirror site of the CASP data and workflows at @sib.swiss. Operating a redundant site with independent funding is a good idea for important scientific infrastructure, independent from the current funding situation in the US.

Exclusive: Famed protein structure competition nears end as NIH grant money runs out Agency silent on funding renewal for contest that inspired creation of AIs that predicted how proteins would fold

Speak up to prevent a major loss for the field. CASP, which helped shaping structural biology including AlphaFold is on the verge of shutting down. NIH funding has lapsed, UC Davis support ends and the core team is being let go. Painfully shortsighted.

Ritscher-Schinzel syndrome can be characterized as an endosomal recyclinopathy The multiorgan phenotypes found in Ritscher-Schinzel syndrome stem from defective endosomal protein recycling, leading to a proposed recyclinopathy.

Congratulations to Kohl Kato and Pete Cullen and all involved in this tour de force characterising mutations in the Commander complex leading to Ritscher-Schinzel or 3C syndrome. @peterjcullen1.bsky.social

Advice from NSF: grant proposals can still include outreach, community engagement, and so on. But avoid specifying particular groups

learned that the NSF indirect cost change would not retroactively alter total grant amount. Let’s say you have a funded 100K IDC grant plus 50K overhead. Total grant is 150K. If IDC changed retroactively from 50% to 15% the total grant would still be 150k.

Sorry to hear this, Sean. We use HMMER all the time--it's a critical tool for our research.
