Characterization of proteins in the yeast Golgi apparatus

The yeast Saccharomyces cerevisiae used in brewing and bread making is a unicellular microorganism and serves as a model system of the eukaryotic cell. Genetic and molecular biochemical studies also provided pioneering discoveries in the field of vesicular trafficking. Recently, our understanding of this field has greatly advanced, however, there still remain unsolved problems. For example, since vesicular trafficking of each component occurs between related organelles, how the Golgi compartments keep their identity as a distinct organelle remains to be solved. Therefore, we carried out studies to investigate these problems.
