AlphaFold AI has profoundly reshaped health data research in a short time: since 2020, DeepMind’s technology has produced protein models with unprecedented accuracy and has made them widely accessible to the community in the spirit of open science—a milestone recognized in 2024 with the Nobel Prize in Chemistry awarded to Demis Hassabis, John Jumper, and David Baker [1–3].

What is AlphaFold AI?​

AlphaFold is an AI-based model for protein structure prediction. In 2020, DeepMind presented a solution to the 50-year-old “protein-folding problem”, and in 2021 it published the methodological foundation (AlphaFold 2) in Nature. In parallel, the AlphaFold Protein Structure Database (AF-DB) was created with EMBL-EBI; today it contains more than 214 million entries—virtually the entire UniProt space. This open resource enables health data research at a new level, from basic science to application [1, 2, 4–6].

Open science: AlphaFold models and the AF-DB are freely accessible; the data (including PAE plots) can be programmatically analyzed. This accelerates hypothesis generation in biomedical research and creates reusable assets for health data research [5, 6].

How does AlphaFold AI work?​

AlphaFold combines deep-learning architectures with multiple sequence alignment (MSA), template information, and geometric representations to compute 3D structures from amino acid sequences. The system assesses quality using, among other metrics, pLDDT (local confidence) and PAE (Predicted Aligned Error) for cross-domain confidence—two measures that help researchers correctly interpret model limitations [2, 7–9].

AlphaFold 3 (2024): The current model extends prediction to biomolecular interactions (proteins, DNA/RNA, ligands/antibodies, ions) via a diffusion-based architecture. This improves the informativeness of binding scenarios, but—like any in-silico method—it still requires experimental validation [3, 10].

AlphaFold AI in scientific discovery​

In drug discovery, AlphaFold shortens the path from target hypothesis to structure, enables target prioritization, and supports the identification of potential protein binding sites. Reviews and case studies document faster hypothesis generation in oncology, infectious diseases, and rare diseases—a clear added value for health data research [11–13]. At the same time, flexibility, allostery, and dynamic pockets remain critical aspects that must be tested experimentally [11].

AlphaFold 3 is already being used in industry-aligned programs (Isomorphic Labs; collaborations with Eli Lilly and Novartis, among others), while non-commercial research can access predictions free of charge via the AlphaFold Server [14–17].

Recognition and awards​

The developers of DeepMind AlphaFold received the 2024 Nobel Prize in Chemistry (Hassabis; Jumper; Baker for computer-aided protein design)—a signal of the scientific significance and lasting impact on structural biology and adjacent fields [3, 18–20].

AlphaFold AI and the future of systems medicine​

With AlphaFold 3, omics integration (genomics, proteomics, metabolomics), and digital twins, the potential to simulate systems biology in a data-driven way—from molecule to patient—is growing. Crucial enablers are the interoperability of clinical and molecular data (e.g., via OMOP CDM, FAIR metadata) and governance aligned with WHO guidance on the ethics and regulation of AI in health care [6, 21, 22].
