Outline of Final Research Achievements

The ubiquitin conjugation system is one of the most important reversible post-translational modification system that regulates functions of proteins in a wide variety of ways. This is one of the eight research projects of 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. Pathophysiological roles of the ligase that generate M1-linked chain and mechanism underlying M1-chain generation was studied. Then, I found that 1. M1-chains are essential for the function of B lymphocytes, 2.the ligase (LUBAC) and de ubiquitinating enzymes (OTULIN and CYLD) that are specific for M1-linked chains always form complex and tune strength of NF-kappaB activation elicited by M1-chains, M1-chains are involved in the oncogenesis of B cell lymphomas, and Aspergillus, an opportunistic pathogen for pneumonia, infects to lung by suppressing the generation of M1-chains.
