| Outline of Final Research Achievements |
Centrioles are duplicated to produce a single copy of each preexisting centriole. At the onset of centriole duplication, the master regulator Plk4 undergoes a dynamic change in its spatial pattern around the preexisting centriole, forming a single duplication site. However, the significance and mechanisms of this pattern transition remain unknown. Based on results from super-resolution imaging and mathematical modeling, we proposed that the self-patterning of Plk4 is crucial for the regulation of centriole duplication. These results, defining the mechanisms of self-organized regulation, provide a fundamental principle for understanding centriole duplication.
