|dc.description.abstract||Caged proteins are macromolecules exhibiting a self-assembled nanoplatform that can be used for detection of biomolecule. We present here the strategy to image apoptotic cells using a nanoplatform of caged protein. For that purpose, cage protein was genetically modified to have two abilities, real-time imaging of apoptosis and cellualr uptake. A high ratio of target peptides to cage formed from self-assembling of cage subints resulted in increase of fluorescence signals per a probe particle, and our cage probe was well cell-permeable and exceedingly biocompatible. We demonstrated that cege probe was specifically cleaved by effector caspase in cell-free conditions, and also finally apoptotic events were imaged real-timely in living cells. Our strategy provides an application to imaging and sensing of other specific protease activities.||-|
