Protein binder design has seen advancements with hallucination-based methods optimizing structure prediction confidence metrics like interface predicted TM-score (ipTM) through backpropagation.
A new method has been proposed to extract statistical likelihoods from structure predictors by interpreting their confidence outputs as an energy-based model (EBM).
Leveraging the Joint Energy-based Modeling framework, pTMEnergy, a statistical energy function derived from predicted inter-residue error distributions, was introduced.
The incorporation of pTMEnergy into BindEnergyCraft (BECraft) design pipeline has shown superior performance over other methods, achieving higher in silico binder success rates and improved results in structure-based virtual screening tasks.
