The paper “Inhibition of protein SUMOylation by davidiin, an ellagitannin from Davidia involucrata” was published in the Journal of Antibiotics. The first author of the paper is Misao Takemoto (formerly Yoneyama), a former student of our lab who completed the PhD program. This paper has screened a natural product library to identify novel small molecule compounds that specifically inhibit SUMOylation, a post-translational modification of proteins.
