"Data found that the abundance of CAP-H2 is increased in mitosis by a Plk1 kinase activity-dependent manner and that inhibition of Plk1 induces a degradation of CAP-H2 through Cdc20-mediated ubiquitin-proteasome machinery. These results suggest that the expression levels of CAP-H2 are regulated by Plk1 and Cdc20 for proper chromosomal organization during mitosis."xsd:string
