The AlphaFold Protein Structure Database was launched on July 22, 2021, as a joint effort between AlphaFold and EMBL-EBI. At launch the database contains AlphaFold-predicted models of protein structures of nearly the full UniProt proteome of humans and 20 model organisms , amounting to over 365,000 proteins.
Interpretation of PAE values allows scientists to understand the level of confidence in the predicted structure of a protein: Lower PAE values between residue pairs from different domains indicate that the model predicts well-defined relative positions and orientations for those domains.
John Michael Jumper (born 1985) [1] is an American chemist and computer scientist. He currently serves as director at Google DeepMind. [2] [3] [4] Jumper and his colleagues created AlphaFold, [5] an artificial intelligence (AI) model to predict protein structures from their amino acid sequence with high accuracy. [6]
Structure prediction software such as AlphaFold rely on co-evolutionary data derived from multiple sequence alignment (MSA) and homologous protein sequences to predict structures of proteins. However, per definition, de novo proteins lack homologous sequences, as they are evolutionarily new. [ 17 ]
According to one of CASP co-founders John Moult, AlphaFold scored around 90 on a 100-point scale of prediction accuracy for moderately difficult protein targets. [19] AlphaFold was made open source in 2021, and in CASP15 in 2022, while DeepMind did not enter, virtually all of the high-ranking teams used AlphaFold or modifications of AlphaFold.
There has been rapid development in computational ability to determine protein structure with programs such as AlphaFold, [2] and the demand for the corresponding protein-ligand docking predictions is driving implementation of software that can find accurate models. Once the protein folding can be predicted accurately along with how the ligands ...
The company draws upon DeepMind's AlphaFold technology, which can be used to predict protein structures in the human body with high accuracy, allowing its researchers to find new target pathways for drug delivery. [7] [8] In December 2022, Isomorphic Labs announced its second office location in Lausanne, Switzerland. [7] [9]
AlphaFold's protein structure prediction results at CASP were described as "transformational" and "astounding". [94] [95] Some researchers noted that the accuracy is not high enough for a third of its predictions, and that it does not reveal the physical mechanism of protein folding for the protein folding problem to be considered solved.
