Title: Mega-scale in-silico structure predictions

◈Speaker: Assistant Prof. Martin Steinegger (School of Biological Sciences, SNU)

The protein folding problem, where you try to predict the 3D structure from a string of amino acids, is one long-standing fundamental problem in biology. Recent advances in machine learning and computational methods enabled our method AlphaFold2 [1] to predict structures at a margin of error similar to crystal structures. Its performance was validated in the most recent Critical Assessment of protein Structure Prediction (CASP) [2,3]. We are expecting a many order of magnitude increase in available structures due to this technology. To extract new insights from this structures we need tools to efficiently analyze them. In this talk we will discuss AlphaFold2 and propose method we develop to compress, organize and compare millions of novel protein structures.
