ExplainableFold: Understanding AlphaFold Prediction with Explainable AI

Black-box AI systems can be made more interpretable: AlphaFold, despite its remarkable accuracy in predicting protein structures, operates as a "black box" where users cannot understand why it makes specific predictions. ExplainableFold addresses this by generating explanations that reveal which amino acids most influence the predicted 3D structure.

Explainability enables scientific validation: By providing "near-experimental understanding of the effects of amino acids on 3D protein structure," the framework allows researchers to verify whether AlphaFold's reasoning aligns with known biological principles, rather than trusting predictions blindly.

Counterfactual explanations offer practical insights: The framework uses counterfactual learning (asking "what if this amino acid were different?") to generate explanations, enabling a "dry-lab experimentation approach" that could reduce the need for costly physical experiments.

Responsible AI requires understanding, not just accuracy: This work demonstrates that high-performing AI systems in science need accompanying explainability tools to be truly trustworthy and useful—accuracy alone is insufficient for scientific applications where understanding the reasoning is critical.

Explainability can accelerate scientific discovery: By making AI predictions interpretable, researchers gain deeper insights into protein structures themselves, potentially leading to new biological discoveries beyond what the AI system was originally designed to do.
