Outline of Final Research Achievements

Angiotensin II receptor type2 (AT2R) play an important role for regulating blood pressure. Recent studies strongly suggest that AT2R not only mediates blood pressure control but also plays an important role in cardiovascular protection such as anti cardiac hypertrophy. To solve AT2R structure is important for understanding of the molecular mechanism of blood pressure control and developing of drug against cardiac hypertrophy.
In this study, our aim is to solve the AT2R structure. We developed AT2R structure specific recognition antibodies to crystallize of AT2R. And we screened more stable AT2R mutant. In the result of this study, complex of AT2R mutant and its specific Fab is crystallized by lipidic cubic phase method successfully. The data of these crystals were collected by micro focus beam line, BL32XU (SPring-8). We have been trying to determine the AT2R structure.
