New paper alert π¨
I am super happy about it, for many reasons!
π₯ 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
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.

Latest from the lab. The conclusion is in the title!
Basically, we found that the KMN complex (outer kinetochore) is fully conserved between plants and fungi/animals, showing deep origin. (reminder, you are closer to a mushroom than a mushroom is to a plant.)
Among the anti-recombinases, FIGNL1 rules them all. So much that inactivating it brings BRCA2-deficient cells to life. Who is responsible for RAD51 loading without BRCA2/FIGNL1, check out the paper to find out! Great collaboration with @raychaudhurilab.bsky.social

Excited to release BoltzGen which brings SOTA folding performance to binder design! The best part of this project is collaborating with a broad network of leading wetlabs that test BoltzGen at an unprecedented scale, showing success on many novel targets and pushing the model to its limits!
