Why Local Quality Matters
Protein motion isn't uniform. Stable cores need tight restraints. Flexible loops need freedom. Local quality scores let us distinguish between them, refining uncertain regions while preserving well-predicted ones.
De Novo Design
Model novel folds where evolutionary information is absent
Mutant Modelling
Capture subtle structural changes that determine stability
