Application of Cryo-Electron Microscopy on Epigenetic Studies

摘要: The architecture and structural details of chromatin assembler, chromatin modifier, and chromatin remodeler, and their complexes with nucleosome and chromatin, are critical for revealing the molecular mechanisms for the establishment, maintenance and regulation of epigenetic information. The fast-developing cryo-electron microscopy (cryo-EM) provides an indispensible tool for the structure determiantion of the huge, multi-subunits, and flexible epigenetic regulation related macromolecular assemblies. In this review, we summarized the recent progresses on EM structural studies of macromolecules and complexes relating to epigenetic regulation.
