| Outline of Final Research Achievements |
We investigated the role of RHD3, a plant homologue of atlastin GTPase, on the membrane fusion of endoplasmic reticulum. Based on analyses of the membrane fusion and the tubular formation in vitro of endoplasmic reticulum isolated from Arabidopsis seedling or cultured cell, RHD3 was revealed to be involved in GTP-dependent membrane fusion of endoplasmic reticulum. Furthermore, the biochemical approach with the chemical cross-linkers showed that the membrane fusion of endoplasmic reticulum was progressed through the formation of RHD3 oligomer by the association with GTP.
