3D-organization and dynamics of human genome chromatin

Faculty


Research Summary

Our research interest is to know how a long string of genomic DNA is three-dimensionally organized in the cell, and how the genome is read out for cellular proliferation, differentiation and development. For this purpose, we are using a unique combination of molecular cell biology and biophysics, such as single molecule imaging, superresolution imaging, X-ray scattering and computational simulation.

Chromatin consists of irregularly folded 10-nm fibers and forms numerous chromatin domains in the cell nuclei. Chromatin dynamically behaves like “liquid”. NPC, nuclear pore complex; NE, nuclear envelope.
