We made FLIP2, a protein fitness benchmark spanning seven new datasets, including enzymes, protein-protein interactions, and light-sensitive proteins, as well as splits that measure generalization relevant to real-world protein engineering campaigns.

most proteins are multi domain but our understanding of how architectures evolve is limited - we mapped 40K chitinases and show a stepwise “grammar” of domain gain/loss and localisation changes that predicts ecological strategy and physiological function.
