Research Field
[The Cell Function Sensing and Therapy Laboratory] conducts research on the spatiotemporal molecular mechanisms of dynamic protein interactions and complex cellular functions related to various diseases through real-time cell imaging and optogenetics technology. To achieve this, we are developing fluorescent protein-based fluorescent molecular sensors and novel optogenetic techniques. Our goals are to understand the molecular-level pathological mechanisms of various diseases, and ultimately to develop gene/cell therapies that can finely regulate cellular functions for the treatement of diseases. To this end, we are conducting research to design key therapeutic proteins that can effectively control cell function.
