To understand life, it is indispensable to understand the function and the structure of proteins that play essential roles inside and outside of cells. Laboratory for Cell-Free Protein Synthesis aims to develop the PURE system, a reconstituted cell-free protein synthesis system, to contribute to the development of techniques for manipulating, analysing, and modeling proteins by establishing a method for diverse protein production without restraint. We are also trying to incorporate into the PURE system the ability for self-replication by synthesizing PURE system components autonomously. Using these techniques, we hope to design and control living systems.

Research Topics

  • Protein production by the PURE system
  • Construction of a self-replication model for cell-free protein synthesis
  • Cell-free protein synthesis on micro-devices
