How will AlphaFold 3 change life sciences research?

Context:

In a Nature paper published in May 2024, scientists at DeepMind led by John Jumper introduced AlphaFold 3, building on its predecessors with even more transformative capabilities.

More on news:

AlphaFold uses machine learning and artificial intelligence (AI) to accurately predict protein structures from an amino acid sequence, seemingly solving the protein-folding problem without learning any of the deeper physical principles that drive this biological process.

What are proteins?

Proteins are one of the most important molecules of life, with almost every biological function from birth to death being regulated by them in some way.
Each protein is made up of a string of smaller building blocks called amino acids, which contain all the information to transform proteins — from a single sequence to a folded, functional 3D structure.

About AlphaFold:

AlphaFold is an artificial intelligence (AI) program developed by DeepMind, a subsidiary of Alphabet, which performs predictions of protein structure.
The program is designed as a deep learning system.
AlphaFold software has had three major versions.
A team of researchers that used AlphaFold 1 (2018) placed first in the overall rankings of the 13th Critical Assessment of Structure Prediction (CASP) in December 2018.

About AlphaFold 2:

AlphaFold 2 predicts the structure of proteins with revolutionary levels of accuracy.But it was limited to proteins only.

About AlphaFold 3:

AlphaFold 3 is more accurate than AlphaFold 2 for predicting the structure of proteins.
It can also predict the structure of DNA, RNA, and all the other molecular components that make up biology. The interaction of all these biomolecules is what makes up the processes of life, so it is important to be able to predict the structure of these interactions.
The new AlphaFold is also more usable by scientists who aren’t experts in machine learning.
AlphaFold 3 predicts protein structures and interactions better than other models used right now.
Academics and companies can potentially use it to find drug candidates that can bind to proteins and help cure diseases.
DeepMind’s spin-off company Isomorphic Labs is using AlphaFold 3 for this very purpose: drug discovery.

Application of AlphaFold 3:

Drug Discovery:
- AlphaFold 3 can drastically reduce drug discovery time by simulating and predicting the action of substances on proteins.
Genomics:
- Genomics can be revolutionized if all genes’ DNA and RNA structure is predicted. Such insights can also be used to treat, develop drugs for genetic diseases, or create individualized medicine.
Test a wider range of molecules:
- Test more molecules: more RNA molecules can be tested.
