| Outline of Final Research Achievements |
To elucidate the molecular mechanism of cellular aging, I focused on Mlp proteins and investigated the molecular mechanism of asymmetric inheritance of damaged protein aggregates. I found the mlp mutant strain of budding yeast showed defects in asymmetric inheritance of damaged protein aggregates and prion propagons and shorter life span. I also found Mlp proteins co-localized with damaged protein aggregates. Thus, Mlp proteins must be scaffolds of aggregated proteins in mother cells and retain these aggregates in mother cells to keep the daughter cells fresh.
