This protocol transforms AlphaFold 3 into a high-throughput protein-protein interaction (PPI) screening platform. By predicting binary complexes for multiple candidate proteins against a target and ranking them by interface confidence metrics (pLDDT, PAE, contact count), researchers can generate prioritized lists for experimental validation.

Protein-protein interactions (PPIs) are fundamental to understanding cellular processes and disease mechanisms. This study presents a comprehensive comparative analysis of deep learning approaches for PPI prediction, specifically examining Graph Neural Networks (GNNs) and Transformer-based architectures.
