Research Abstract |
Dynamic analyses of subcellular structures using pinpoint functional depletion The purpose of this project is to reveal the dynamics of cell division in animals and plants using pinpoint functional depletion. The pinpoint functional depletion using a chromosomal protein RBMX fused with a photosensitizer protein was successfully performed by high-power laser. Spatiotemporal inactivation of RBMX with the photosensitizer was performed in combination with live cell imaging. At the result, RBMX interaction with chromatin is turned out through the spatiotemporal inactivation. This method to induce the delay of cell division can be performed through generation of reactive oxygen species and structural destruction of the protein complex by laser irradiation to fluorescent protein-labelled subcellular structures.
