Outline of Final Research Achievements

Ubiquitin, a proteinous post-translational modifier, has been studied as a part of protein degradation system. However, it is now widely recognized that the ubiquitin system is involved in the regulation of a wide variety of biological phenomena by modulating protein functions in many ways. Since dissection methods of the ubiquitin system become diversified and highly developed, it is almost impossible to do all the dissections in one laboratory. “New aspect of the ubiquitin system : its enormous roles in protein regulation”, an research area of Grant-in-Aid for Scientific Research on Innovative Areas was organized to develop cutting-edge technologies to dissect the ubiquitin system and tried to identify new roles of the ubiquitin system in the regulation of biological phenomena. This research project is a headquarter of the research area and handled advertisement, organizing conference for young as well as foreign researchers and promoting collaborations within research areas.
