| Outline of Final Research Achievements |
Ubiquitin chain in different topologies related to distinct functional consequences, including protein degradation, NF-κB activation, and DNA repair. The ubiquitin chain assembly is mostly promoted by E2s, but the linkage specificity by E2s is hardly understood. In this study, we searched for UBE2S inhibitors from natural sources as bio-probes to study the mechanisms of K11-ubiquitin chain elongation. We established the in-house screening system for UBE2S inhibitors and found the several positive extracts from our library of extracts of natural sources. The isolation and structure determination of the inhibitors are in progress.
