Summary
ER and Golgi, are responsible for glycosylation, a universal post-translational modification that occurs on more than 60% of proteins. In this study, we are planning to develop a method to selectively deliver glycan-structure-regulating molecules to the ER or Golgi. Until now, glycans have been regarded as an undruggable target due to the difficulty of their structure regulation. This study is expected to provide the useful tool to change glycan structures, changing glycans into the druggable targets and opening the door to the development of glycoldrug.

Comment

We want to realize glycoldrug.

Outline of Research Achievments

Glycosylation is the most ubiquitous post-translational modification and is involved in numerous biological processes. However, because glycans are bio-synthesized in a non-templated process, it is difficult to regulate their structures using genetic approaches, and their functions remain largely unelucidated. In this study, we developed glycan editing methods, aiming to understand and regulate glycan functions. We developed inhibitors of the core fucose biosynthetic enzyme, which plays a critical role in immune regulation. Additionally, we successfully introduced synthetic glycans onto proteins and controlled their dynamics and functions.
