Outline of Final Research Achievements |
In the biomembranes, lipids are not randomly distributed. Rather, lipids are asymmetrically distributed between outer and inner membrane bilayer. Even in one layer, lipids form domains. However, the detailed distribution of lipids in biomembranes are not yet elucidated. We have developed various protein probes that bind specific lipids or lipid domains. Using these probes in combination with state-of-the-art microscopy techniques, we clarified the detailed distribution of lipid domains, including lipid rafts, in biomembranes. Application of our strategy to various pathophysiological events such as cell division, cell adhesion and genetic defects in cholesterol and sphingolipid metabolism provided us new aspects of lipid domains.
