Research themes

Regulation of enzymatic activity by post-translational modification

Brief explanation of research

Amount of protein expression is regulated by "synthesis" and "degradation". Ubiquitin modification (ubiquitylation)-dependent protein degradation is important and failure of this system causes many types of diseases. In contrast, ubiquitin-like protein ISG15 also modifies proteins (ISGylation). So far, the role of ISGylation has not been cleared, but we hypothesize that the ISGylation may activate enzymes. We are going to keep studying both ubiquitylation and ISGylation.
