Cep63 Recruits Cdk1 to the Centrosome: Implications for Regulation of Mitotic Entry, Centrosome Amplification, and Genome Maintenance

Original language description

Centrosomes are central regulators of mitosis that are often amplified in cancer cells. Centrosomes function both as organizers of the mitotic spindle and as reaction centers to trigger activation of Cdk1 and G(2)/M transition in the cell cycle, but their functional organization remains incomplete. Recent proteomic studies have identified novel components of the human centrosome including Cep63, a protein of unknown function that Xenopus studies have implicated in mitotic spindle assembly and spindle inactivation after DNA damage. Here, we report that human Cep63 binds to and recruits Cdk1 to centrosomes, and thereby regulates mitotic entry. RNAi-mediated Cep63 depletion in U2OS cancer cells induced polyploidization through mitotic skipping. Elicitation of this phenotype was associated with downregulation of centrosomal Cdk1, mimicking the phenotype induced by direct depletion of Cdk1. In contrast, Cep63 overexpression induced de novo centrosome amplification during cell-cycle interpha
