AlphaProteo designs high-affinity protein binders
Including the first AI-designed VEGF-A binder
Result confirmed
The takeaway
DeepMind’s AlphaProteo generated protein binders for 7 targets with 9–88% experimental success rates (88% for BHRF1) and 3–300× better affinities than prior methods.

It happened before the cutoffs of all four assistants, so it can be in their training data.
Key facts
- Experimental binding success 9–88% across 7 targets
- Affinities 3–300× better than the best previous methods on several targets
- Technical report, not peer-reviewed at announcement
What happened
DeepMind released a binder-design system and reported wet-lab results from partner labs.
Why it matters
High one-shot success rates cut the months of screening normally needed to find a binder.
