Research Abstract

In this research project, I newly discovered GS protein whose expression is regulated specifically different way in the cardiomyocyte. GS regulates the function of ATP synthesis. We also purified and identified a new AMPK substrate; CLIP-170 and clarified the regulatory role of AMPK in microtubule polymerization. Both discoveries lead to the understanding of novel cellular stress response in cardiomyocyte and the therapeutic approach of the cardiovascular diseases.
