Outline of Final Research Achievements

Fluorescence polarization allows detailed analysis of both orientations and positions of biomolecules at a single molecule level. We have developed a novel labeling method for fluorescence polarization imaging and investigated its usefulness in cell biology. We have successfully discovered previously unknown dynamics of actin-related structures in starfish oocytes by using a probe for actin. We also succeeded in improvements of the probe for multicolor imaging along with modifications of microscope settings.

Academic Significance and Societal Importance of the Research Achievements

新規開発に成功した標識法は、本研究計画の成果である多色化等の改良により、汎用性が向上し、将来的に蛍光偏光を利用した生命科学領域におけるイメージングや計測の応用可能性が拡張された。また、細胞骨格分子を標的とした私たちのグループの応用例の成果から明らかなように、学術的意義を有する知見の蓄積が期待できる。細胞生物学、生物物理学、発生生物学の他、基礎生命科学から蛍光計測を利用する応用生命科学まで、広範囲の応用成果が見込まれ、その社会的意義は大きい。
