Proteins are the building blocks of life of living organisms, and they’re packed into every cell of our bodies. To understand protein function and make full use of this information, researchers need to understand protein geometry and how they fold.
If you want to produce a treatment or an immune reaction in the body, and the protein used doesn’t fold appropriately, it could not only render the treatment useless, but even make it dangerous. Several degenerative diseases and allergies are caused by incorrect folding of some proteins, because the immune system doesn’t produce antibodies for some protein structures.
Predicting protein folding, however, is a tough job. Researchers have been struggling with it for decades, and even with advanced computers and software, it still takes a lot of effort. This is where DeepMind’s AI comes in.
