AI has been used to predict the structures of almost every protein made by the human body.
The development could help supercharge the discovery of new drugs to treat disease, alongside other applications.
Proteins are essential building blocks of living organisms; every cell we have in us is packed with them.
Understanding the shapes of proteins is critical for advancing medicine, but until now, only a fraction of these have been worked out.
Researchers used a program called AlphaFold to predict the structures of 350,000 proteins belonging to humans and other organisms.
The instructions for making human proteins are contained in our genomes - the DNA contained in the nuclei of human cells.
There are around 20,000 of these proteins expressed by the human genome. Collectively, biologists refer to this full complement as the "proteome".
Commenting on the results from AlphaFold, Dr Demis Hassabis, chief executive and co-founder of artificial intelligence company Deep Mind, said: "We believe it's the most complete and accurate picture of the human proteome to date.
