Description

Hao Du's team better protein-protein interaction forecast by pre-training on pseudo-dimers built from abundant monomeric proteins, addressing the scarcity of dimer shapes that limits models such as AlphaFold-Multimer and AlphaFold3. Collecting true dimer shapes is expensive and slow.

Their split-and-merge proxy splits monomers into pseudo-sensor and pseudo-ligand halves and trains models to rejoin them by predicting contacts or docking, enabling large-scale pre-training at no extra cost. Fine-tuned models beat strong baselines across benchmarks and surpassed both AlphaFold systems on several CASP15 dimer targets.
