RIKEN Center for Integrative Medical Sciences Laboratory for Protein Functional and Structural Biology
Team Director: Mikako Shirouzu (Ph.D.)
Research Summary
The high-resolution structural information of proteins related to diseases shall increasingly become important for drug development leading to future individualized medicine. We plan to establish a structural analysis technology platform to contribute to "Life innovation" such as drug discovery as well as development of methods for the sample preparation of challenging proteins including membrane proteins/biomolecular complexes and for the structural analysis by cryo-electron microscopy (cryo-EM). The 3D-structural information will be used for in-silico screening/design of chemical compounds and for dynamic structural analysis toward simulation research of cell function.
