| Outline of Final Research Achievements |
In humans, an absence of stomatin is associated with a form of hemolytic anemia known as hereditary stomatocytosis. In this study, I tried to elucidate how the partner protein STOPP (STomatin Operon Partner Protein) regulates the oligomeric protein stomatin. By X-ray crystallography, I elucidated that the protease domain of STOPP could form a different dimeric structure, and that the OB (Oligonucleotide Binding) domain of STOPP could assemble into 12-24 mer multimers based on a dimer as a basic unit. This result indicates that the OB domain functions as a scaffold protein to form the multimeric assembly of STOPP and stomatin. In the future, I want to elucidate the mechanism how hereditary stomatocytosis is developed.
