Shusuke Tomoshige completed his Ph.D. in pharmaceutical sciences at The University of Tokyo, Japan, in 2016 under the supervision of Prof. Yuichi Hashimoto. After his postdoctoral training for two years at University of Notre Dame, USA, under the guidance of Prof. Shahriar Mobashery, he joined Tokyo University of Science, Japan. Since September 2019, He has been appointed as an assistant professor at the Graduate School of Life Sciences, Tohoku University, Japan, working with Prof. Minoru Ishikawa.

Recent Activities

I have been working on the research on the degradation machinery of biopolymers (e.g. proteins and cell wall), especially ubiquitin-proteasome system (UPS). Recently, we have achieved the targeted protein knockdown of proteins involved in neurodegenerative disorders mediated by small molecules harnessing a ubiquitin ligase (E3), an enzyme conjugating ubiquitin to substrates, and currently are making an effort to expand the scope of the compounds. Also, I am challenging to develop the novel small molecules hijacking another E3.

Message to Students

The Ishikawa group (Bioactive Molecules lab.) has just started in April, 2019 and we are pleased to work with the Tohoku University members. Our group carry out interdisciplinary studies integrating computation, molecular biology, and organic syntheses of medically important bioactive molecules. Motivated students are highly welcomed to commence their post-graduate programs in our group. Feel free to contact me by e-mail if you are weighing joining our group.
