一、主 题：Intelligent 3D Cryo-EM Image Analysis for Next Generation Biomedicine
Life ultimately depends on the interactions of large biological molecules, such as proteins. The nature of these interactions depends on the three dimensional (3D) shape and structure of these molecules. Electron cryo-microscopy (cryo-EM) as a cutting edge technology has carved a niche for itself in the study of large-scale protein complex. The accuracy of secondary structures and backbone structure detection from the volumetric protein density images is critical for ab initio modeling in cryo-EM. So far it is challenging to detect the SSEs and backbone structures automatically and accurately from the density images at medium-high resolutions. We have combined image processing, machine learning and geometric modeling techniques and developed SSETracer, SSELearner, StrandTwister, StrandRoller, BarrelMiner along with recent developed deep learning framework to allow for the automatic and accurate prediction of secondary structures and backbone structures from experimental derived 3D cryo-EM images of protein complexes.
