Elucidation of the Mechanisms Underlying Dynamical Ordering of Biomolecular Systems for Creation of Integrated Functions

Living systems are characterized as dynamic processes of assembly and disassembly of various biomolecules that are self-organized, interacting with the external environment. The omics-based approaches developed in recent decades have provided comprehensive information regarding biomolecules as parts of living organisms. However, fundamental questions still remain unsolved as to how these biomolecules are ordered autonomously to form flexible and robust systems. We develop multidisciplinary research area, including fields of biology, chemistry, physics, and aims to elucidate the mechanisms underlying the dynamic ordering of biomolecules for the creation of integrated functions.
