DeepSummary
This episode explores how artificial intelligence (AI) has revolutionized the field of protein science, enabling scientists to solve a long-standing problem: determining the complex 3D shapes of proteins. Traditionally, experimental methods to map protein structures were tedious and often unsuccessful. In 2020, Google DeepMind's AI model AlphaFold2 outperformed all other methods in a protein structure prediction competition, accurately predicting millions of protein shapes.
The impact of AlphaFold has been significant, allowing researchers like Julian Bergeron to rapidly progress in their work on understanding the intricate machinery of bacterial flagella. The recently released AlphaFold3 can now model not just proteins but also their interactions with other biomolecules, providing a more comprehensive picture of biological processes.
Beyond predicting existing protein structures, AI is also being used to design entirely new proteins not found in nature. Scientists like David Baker are using AI to engineer proteins that could tackle challenges like disease, climate change, and sustainable technology. While limitations remain, AI has fundamentally transformed the protein science landscape, accelerating progress and opening up new possibilities.
Key Episodes Takeaways

- “I think really, across medicine, sustainability, technology, I think there's huge opportunities to transform the current ways we do things with protein design.“ by David Baker
- “The mission statement that we have for the science program at Google DeepMind is to leverage AI to accelerate and advance science.“ by Pushmit Kohli
- “So it really gives you a more detailed and more accurate picture of what is happening inside the body, where proteins are just not just sort of existing in isolation, they are interacting in a very rich biological space, or soup of rna and DNA and small molecules, and it really sheds light into those rich interactions.“ by Pushmit Kohli
