| Outline of Final Research Achievements |
F-BAR domain protein Syndapin is essential for membrane dynamics during cytokinesis. Syndapin is phosphoregulated in cytokinesis but responsible kinases and phosphatases remained unclear. In this study, we identified PP1 phosphatases are required for Syndapin localisation to the cleavage furrow during cytokinesis. Furthermore, one of the essential mitotic kinases Plk1 directly phosphorylated Syndapin in vitro. These results suggested that Syndapin function during cytokinesis is spatially and temporally phosphoregulated by counter action of PP1 phosphatases and Polo-like kinase.
