The ubiquitin-proteasome system is believed to play an important role in the determination of cell sensitivity to methylmercury. The ubiquitin ligase enzyme is involved in the recognition of substrate proteins that are degraded by the ubiquitin-proteasome system. In this study, the ubiquitin ligase species affecting methylmercury sensitivity was investigated by the gene interference method. We found that the inhibition of expression of the gene for Cell division cycle 23 (CDC23), a constitutional component of the ubiquitin ligase anaphase promoting complex/cyclosome, sensitized HEK 293 cells to methylmercury.
