Outline of Final Research Achievements |
I found that the AMP-activated protein kinase (AMPK) phosphorylates several proteins of tight junction (TJ). I showed that when cingulin, it is tight junctional protein, was phosphorylated by AMPK, the molecular configurational change occurred. By exploiting this conformational alteration regulated by AMPK, I try to design a module that undergoes efficient fluorescence resonance energy transfer (FRET). FRET probe is possible to be a powerful tool to visualize the intracellular nutritional condition by observing the activity of AMPK.
