Excited to share our paper with @savitski-lab.bsky.social, led by @tarabartolec.bsky.social, Karin Mitosch & Clément Potel, out now in @nature.com. We show that T7 phage broadly disables bacterial defenses using a unique ‘loose cannon’ protein kinase. www.nature.com/articles/s41...

Excited to share our preprint with @savitski_lab led by @tarabartolec.bsky.social, @KMitosch & Clément Potel! We uncovered a mechanism by which the T7 phage broadly counteracts DNA-targeting bacterial defenses by deploying a loose cannon kinase in its genome @embl.org www.biorxiv.org/content/10.1...

1/5 How much phosphorylation can a single kinase deposit? In our new study with @typaslab.bsky.social out in @nature.com, phage T7's kinase (T7K) modifies almost all the E. coli proteome + more densely than all ~500 kinases do our own proteomes 🤯 www.nature.com/articles/s41...

1/11 - With Karin Mitosch and Clément Potel + colleagues in Savitski lab and @typaslab.bsky.social @embl.org, I’m very happy to share our discovery of a hyper-promiscuous phage protein kinase (T7K) which broadly deactivates bacterial defenses! 🦠 www.biorxiv.org/content/10.1...

You asked, we listened. Millions of AI-predicted protein complex structures are now available in the #AlphaFold Database. This spans homodimers from 20 of the most studied species, including humans, as well as the World Health Organization’s priority pathogens list. www.ebi.ac.uk/about/news/t...

10 years and still standing strong @EMBL 🍾💪 Huge thanks to all members, alumni, supporters & colleagues who made it possible. Here’s to the next decade! 🙏

When I first learned about omics at university, I confidently stopped caring about single proteins. Fast-forward 4 years of a system’s biology PhD, I now have the most amazing favorite single protein which I can’t stop thinking about. Here is the story of how that happened 👀
