# AlphaFold AlphaFold is the protein-structure prediction system from [[Google DeepMind]]. It predicts the 3D structure of a protein from its amino-acid sequence with accuracy competitive with experimental methods (X-ray crystallography, cryo-EM), and it effectively solved a 50-year open problem in structural biology. ## Generations - **AlphaFold 1** (2018) — first version; won CASP13 but still gap to experimental accuracy - **AlphaFold 2** (2020) — the breakthrough; at CASP14 it produced predictions for most targets at near-experimental accuracy - **AlphaFold 3** (2024) — extended beyond single-protein structure to protein-ligand, protein-nucleic-acid, and protein-protein complexes; uses a diffusion-based architecture ## Impact - **AlphaFold Protein Structure Database** (with EMBL-EBI) released predicted structures for ~200 million proteins, essentially the entire known protein universe, available to researchers for free - Accelerated drug discovery, enzyme design, and fundamental biology research - [[Demis Hassabis]] and [[John Jumper]] awarded the **Nobel Prize in Chemistry 2024** for AlphaFold; [[David Baker]] shared the prize for related protein-design work - One of the most consequential scientific AI deployments to date; the "proof of concept" argument for AI-for-science at large ## Why it matters - Demonstrates that deep learning systems can solve long-standing scientific problems, not just pattern-match on internet text - Gives [[Google DeepMind]] a durable differentiation axis vs pure-LLM competitors ([[OpenAI]], [[Anthropic]], Chinese labs): the ability to couple LLM work with domain-specific scientific models - Sets the template for follow-on "Alpha" scientific systems (AlphaMissense, AlphaGeometry, AlphaProof, GNoME for materials) ## References - AlphaFold Protein Structure Database: https://alphafold.ebi.ac.uk - Nature paper (AlphaFold 2): https://www.nature.com/articles/s41586-021-03819-2 - AlphaFold 3: https://www.nature.com/articles/s41586-024-07487-w - Nobel Prize 2024 (Chemistry): https://www.nobelprize.org/prizes/chemistry/2024/ ## Related - [[Google DeepMind]] - [[Demis Hassabis]] - [[John Jumper]] - [[AlphaGo]] - [[Gemini]] - [[Artificial Intelligence (AI)]]
