| Outline of Final Research Achievements |
Our proteomics analysis of mitotic chromosomes revealed that uncharacterized protein MKT4 localizes to centromere in mitosis. Functional analysis suggested the involvement of MKT4 in the mitotic spindle checkpoint depending on microtubules. Moreover MKT4 shows most strong kinetochore localization in prophase and disassociation by anaphase onset. In this study, we found another novel centromere protein ZNF518B which associates centromere through the cell cycle. ZNF518B and its homolog ZNF518A interact Heterochromatin protein 1 (HP1) and Centromere protein B (CENP-B), which associate pericentromere region in chromosomes.
