| Outline of Final Research Achievements |
Prospore membrane formation in budding yeast is developmental process and is regarded as a model for de novo membrane formation. Rab GTPase, Sec4 and its GTP exchange factor, Sec2 function in the fusion of post-Golgi vesicles to plasma membrane. The conditional mutant, in which Sec2 expression is specifically repressed during sporulation, was generated and analyzed for prospore membrane formation. Electron and light microscopic observation suggest that prospore membrane formation in the mutant was not uniform and included irregular spore wall materials. Further analysis revealed that some but not all effector proteins and cargo proteins were not delivered effectively to prospore membrane in the mutant. Although more extensive analysis will be required, but our analysis could provide some clues regarding de novo membrane formation in the cells.
