Outline of Final Research Achievements

In this study I got following three results which indicated that kendrin and Cep152 may regulate the centrosome duplication. At first, kendrin and Cep152 can interact via their carboxyl terminals. Second, although Cep152 may not localize at the centrosome during G2/M phase they were recruited to the centrosome again during cytokinesis. Third, by siRNA mediated- kendrin depletion, expression level of Cep152 were increased and Cep152 could localize at the centrosome efficiently rather than normal condition. Taken together I found that Cep152 might be recruited efficiently to the centrosome after kendrin was released and that this mechanism could facilitate centrosome duplication at next cell cycle.
