New paper alert 🚨
I am super happy about it, for many reasons!
👥 It was a great collaborative project with Calum @chgjohnston.bsky.social and J. Pablo Radicella, designed a long time ago (in the pre-AlphaFold era - can you imagine?) together with @polardlab.bsky.social and @raphguerois.bsky.social
Pleased to share our recent article in PNAS - a collaboration with @jessicaandreani.bsky.social & Pablo Radicella, with important roles played by many members of each team.

Elegant PNAS paper on the ComEC/ComFA/ComFC complex in bacterial transformation. AF3 predictions validated by clever mutagenesis. We tried for years to solve this by cryo-EM/crystallography - never succeeded.

How do new centromeres evolve while staying compatible with the division machinery?

Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore.

Proteins are dynamic structures, but structural biology often shows them as static snapshots. Inspired by long-exposure photography and generative art, I built ProteinCHAOS, an artistic tool inspired by molecular dynamics to capture protein flexibility over time, much like long-exposure images.
