A deserved celebration after the hard work 🍾🥂. @waelskamel.bsky.social and collaborators from the @castello-lab.bsky.social discovered that the U2 snRNP displays a moonlighting antiviral role and uses the U2 snRNA to interact with viral RNA 🤯🤯🤯 t.co/DJlXFxmGEv

Are you thinking on an exciting PHD project at the interface of translation control and innate immunity? @rnanomad.bsky.social and I have a project that might interest you!

@alf-castello.bsky.social & I are inviting applications for a competitive PhD studentship to study the mechanisms of translational regulation of the host response to RNA virus infections. The student will be based at Uni. Glasgow. Please spread the word. #RNASky

Our new PLOS Pathogens paper with ‪@brennanlab.bsky.social‬ is out! We charted the first protein–RNA interaction map for virus-infected tick cells, revealing 283 RNA-binding proteins reshaped by Uukuniemi virus. Some directly control viral particle output. Full story: doi.org/10.1371/jour...
Uukuniemi virus infection causes a pervasive remodelling of the RNA-binding proteome in tick cells
Author summary In host cells, RNA-binding proteins play essential roles in the life cycle of many viruses by influencing how viral RNA is processed, translated, replicated and assembled into virions. ...

Post 5/5 🧵
IMPACT: This transforms tick-borne disease research:
🎯 New drug targets
🎯 Understanding vector competence
🎯 Virus-tick evolution
Testing if mechanisms work across other tick viruses next.

🚀 New from Cell: SPIDR is a game-changer—map dozens to hundreds of RNA-binding proteins simultaneously with single-nucleotide precision in one CLIP experiment. An exciting advance for RNA–protein interactomics! 🧬🔗https://doi.org/10.1016/j.cell.2025.06.042

Happy to see Honglin Chen's paper published! 🎉🎉🍾🥂. Great collaboration with @shabazlab.bsky.social to discover the discordances between RNA and protein in the interferon response...

Pre-print is up! SARS-2 produces a truncated N protein to antagonize multiple antiviral pathways. A very collaborative project in the @corcoranlab.bsky.social with @nogasharlin.bsky.social, Danyel Evseev, and Max Bui-Marinos, and of course the boss Jenn Corcoran

At this END of YEAR please check out our new paper on GENE ENDS and a convenient marker of transcription termination: RNAPII CTD T4ph! We think it is relevant to anyone studying human/animal #genes and #genome so put a lot of effort to make it easy to read. #RNABiology and #Epigenetics meet:)

Do you know where transcription of a gene actually stops? Hint: it is not the annotated gene end.
In our new paper in Nucleic Acids Research we argue that phosphorylation on threonine 4 of RNA Pol II CTD is a marker of transcription termination in animals... 🧵

These studies are so important. Well done to the authors and the journal for publishing it. This certainly applies to so many antibodies. Companies selling antibodies should do and provide the right controls before commercialisation.

Please check out our paper in collaboration with Nahum Sonenberg's group. We show how some DNA viruses co-opt the host cell translation machinery to repress the cGAS/STING response.
TLDR; the cap-binding protein 4EHP represses the cGAS mRNA translation.

I am just going to plug-in the latest paper from our lab, wherein we show that treatment with the chemotherapy agent 5-Fluorouracil (5-FU) induces ribosome collision and that RQC pathway mitigates the 5FU-induced cytotoxicity. #RNA, #RNASky, #Cancer

🦸 Hidden superheroes in our cells!?

@waelskamel.bsky.social, @castello-lab.bsky.social & the Rosalind Franklin Institute have uncovered how a team of cellular “superheroes” leap into action to stop viruses in their tracks.
