2 Figure 1 A Model for the Regulation of CENP-A Assembly
CDK and Plk1 act as master regulators of CENP-A assembly timing. Plk1 phosphorylation of Mis18BP1 enables its recruitment to centromeres early in mitosis through an interaction with CENP-C. CDK activity during G2 and mitosis phosphorylates CENP-A and HJURP, preventing their association until CDK activity drops during anaphase. CDK activity also prevents the association of Mis18α/β with Mis18BP1. As CDK activity drops in late mitosis, HJURP, CENP-A, and H4 are recruited to centromeres through an interaction between Mis18β and HJURP that enables incorporation of CENP-A and H4 into nucleosomes.
