RIKEN Center for Brain Science Laboratory for Protein Conformation Diseases
Team Director: Motomasa Tanaka (Ph.D.)
Research Summary
We are investigating the molecular basis of neurodegenerative disorders and psychiatric diseases using both in vivo and in vitro systems via a variety of techniques including neurobiology, structural biology, genetics and proteomics. In conjunction, we are seeking to uncover the structural basis of yeast prion strains and transmission barriers, and to identify novel functional prions or protein aggregates that play physiological roles in cells.
