The design of the neural network used in AlphaFold 2, according to the Nature paper, is complicated. The system has also already proven that it can accurately predict the shape of some key proteins associated with SARS-CoV-2, the virus that causes COVID-19. In its Nature paper, DeepMind wrote that AlphaFold 2 has already helped those who study X-ray crystallography and electron microscope images of proteins to better refine their understanding of what they are seeing in that data. “Today we take the first step toward delivering on that commitment.” Hassabis promised to share more updates “soon” on the company’s progress toward making AlphaFold2’s predictions more widely available.

“We pledged to share our methods and provide broad, free access to the scientific community,” Demis Hassabis, DeepMind’s cofounder and chief executive officer, said in a statement.

Having the source code would still require non-DeepMind scientists to train the neural network themselves before they could derive useful protein structure predictions. The company has said previously that it may develop an interface that would allow academic researchers and possibly even pharmaceutical companies to simply query AlphaFold 2 for protein structure predictions, but the company has not yet announced any such access. It has also open-sourced the code it used to create AlphaFold 2 for other researchers to use. Today, in a peer-reviewed paper published in the prestigious scientific journal Nature, DeepMind offered further details of how exactly its A.I. company’s team win the contest, the CASP organizers themselves declared that DeepMind had essentially solved the protein structure prediction problem as Anfinsen had first formulated it. This time it was able to make predictions that were so accurate across most protein types that not only did the A.I. Last year, DeepMind entered again with a redesigned deep-learning system, AlphaFold 2. DeepMind’s system, which it called AlphaFold, handily beat all the other teams, making a big leap forward in prediction accuracy, although it was still far from equaling the accuracy of X-ray crystallography.

In 2018, DeepMind-which is owned by Google parent-company Alphabet-entered the competition for the first time using a deep-learning system, a kind of artificial intelligence that uses neural networks: software that is loosely based on the way connections in the human brain work.

A biennial contest for software that could accurately predict protein structure from genetic sequences, called the Critical Assessment of Protein Structure (or CASP) competition, began in 1994.

At the time, however, the computational methods, the gene sequencing techniques, and just as important, the computing power, to work out such complex correlations did not exist. But back in 1972, Nobel laureate chemist Christian Anfinsen postulated that it should be possible to accurately predict the exact shape a protein will fold into just by looking at its DNA sequence. More recently, other methods have been used, such as flash-freezing the proteins at extremely low temperatures and then examining them in electron microscopes. But the method is expensive, time-consuming, and sometimes fraught. One of the most accurate is X-ray crystallography, in which a solution of proteins is crystallized and then bombarded with high-powered X-rays and the resulting diffraction patterns analyzed to build up a picture of the protein. The shape of a proteins is usually determined using some kind of imaging method. So knowing the exact shape of the protein can be a critical step in the development of new pharmaceuticals, and DeepMind’s breakthrough has the potential to accelerate drug discovery. Most drugs work by binding to very specifically shaped “pockets” within the structure of a protein. The shape of a protein is important because it helps determine that protein’s function. software to predict the shape into which proteins would fold based solely on their genetic code. DeepMind, the London-based artificial intelligence company, has published further details of how it solved a 50-year-old scientific challenge late last year, using A.I.
