About our laboratory

Dr.Shigetsugu HatakeyamaDepartment of Biochemistry (formerly Biochemistry II), established in 1963, is one with tradition and history, having been led by professors You Imai and Teruo Ishibashi, renowned for their work on lipid research.

 

Since 2004, with the leadership of professor Shigetsugu Hatakeyama, it has been conducting research on the degradation control of proteins with a focus on ubiquitination, a post-translational modification of proteins.

 

Related fields of research include fundamental biology fields such as cellular biology, immunology, neuroscience, and molecular biology, and clinical fields, including cancer and neurodegenerative disease.

 

Ubiquitin, as a system of intracellular protein degradation, has a history of barely 20 years, and, less than a 10 year history as a new field of biology since the discovery of its related enzyme systems on a molecular level. Further, it was only recently that, aside from protein degradation, other functions, such as endocytosis, translational control, DNA repair, histone control, etc., have become understood.

 

As for the objective of fundamental research, it is the identification and functional analysis of ubiquitination enzyme systems, additionally, as for clinical medical research, it is the investigation into the involvement of ubiquitination and phosphorylation with respect to diseases related to cancer, the immune system, and neurodegeneration, with a view to advancing research into prevention and cure.
