AlphaFold-Multimer can predict interactions for complexes of up to several protein chains with accuracy approaching that of experimentally determined structures.
By extending AlphaFold’s single-chain prediction to multi-chain complexes, AlphaFold-Multimer predicts protein-protein interactions at atomic resolution. It incorporates co-evolutionary data, inter-chain contacts, and geometric constraints to model stable complexes. Researchers use these predictions to understand signaling pathways, enzyme assemblies, and immune system interactions. The model outputs include confidence metrics for interface residues, guiding experimental validation. Integration with docking simulations enhances precision. Applications include rational drug design, synthetic biology, and functional annotation of uncharacterized proteins. The AI accelerates understanding of molecular interaction networks without requiring full experimental complex determination.
