Outline of Final Research Achievements

This research aimed at regulating subcellular localization of proteins through their catalytic chemical modifications in living cells as a new method for functional regulations of the proteins. I succeeded in developing a novel catalyst system to enable protein-selective acylation, and I found that a protein modified by the catalyst system (fatty acylation) localized in liposomes. I, furthermore, succeeded in protein-selective acylation in living cells using the catalyst system. Although I, unfortunately, have not achieved subcellular localization control in living cells, I believe that this research achievement paved a way for a new method of regulating protein functions through a novel mechanism.
