| Outline of Final Research Achievements |
To contribute to the elucidation of nuclear transport mechanisms we have (1) predicted the structure of the complex formed between transcription factor Oct3/4 and importin α; (2) performed a comprehensive analysis of the dynamic structure of nuclear localization signals (NLS); and (3) elucidated the release mechanism of cargo proteins from importin α. In addition, we identified two NLS sites in epigenetic factor EZH2 and inferred its nuclear import mechanism. Furthermore, we designed and developed chemical compounds that inhibit the formation of the PRC2 complex including EZH2 and then explored their potential for the targeted therapy of lymphomas and other cancers.
