AF3Complex

AF3Complex modifies AlphaFold 3 to improve prediction of protein complex structures, particularly for challenging types such as protein-peptide and antibody-antigen complexes.

Key Features:

• Enhanced Complex Prediction: Incorporates similar and novel improvements to AlphaFold 3, building on strategies previously used in AF2Complex.
• Superior Benchmarking Performance: Outperforms AlphaFold 3 on a large dataset of protein complexes in benchmarking tests.
• High-Fidelity Structure Generation: Generates high-fidelity structures for challenging complex types including protein-peptide complexes and antibody-antigen complexes.
• CASP16-Grade Predictions: Yields structural predictions for protein complexes that would have placed among the top models in the CASP16 competition.

Scientific Applications:

• Protein Complex Structure Prediction: Predicts accurate structures of protein complexes essential for understanding biological pathway function.
• Protein-Peptide Complex Modeling: Creates high-fidelity structural predictions for protein-peptide complexes.
• Antibody-Antigen Complex Modeling: Creates high-fidelity structural predictions for antibody-antigen complexes.

Methodology:

AF3Complex applies downstream modifications to AlphaFold 3, incorporating both similar and novel improvements relative to those previously developed for AF2Complex.
