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.

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 👀
