| Outline of Final Research Achievements |
In ovarian cancers, gankyrin and Nedd8 are overexpressed. In vitro gankyrin neddylation assay (bacteria-expressed and purified E1, E2, Mdm2, Nedd8, gankyrin, ATP) produces gankyrin mononeddylation, that is verified by western blot of anti-gankyrin antibody and anti-Nedd8 antibody. Due to synthetic biological method, polycistronic affinity-tagged gankyrin, Nedd8, E1, E2, and Mdm2 are expressed into Rosetta bacterial cells. Gankyrin mononeddylation occurs. This expressed and purified mononeddylated gankyrin enhances p53 and pRB polyubiquitylation and 26S proteasome-mediated protein degradation. This effect is enhanced by full-length S6 ATPase co-expression. However it is suppressed by C-terminal truncated S6 ATPase mutant.
