Abstract/OtherAbstract:
Phosphatidylinositol 4,5-bisphosphate-regulated phosphatidylcholine-specific phospholipase D is conserved from yeast to man. The essential role of this enzyme in yeast is to mediate the fusion of Golgi and endosome-derived vesicles to generate the prospore membrane during the developmental program of sporulation, through the production of the fusogenic lipid phosphatidic acid. In addition to recruiting proteins required for fusion, phosphatidic acid is believed to lower the energy barrier to stimulate membrane curvature. During mitotic growth, phospholipase D activity is dispensable unless the major phosphatidylinositol/phosphatidylcholine transfer protein is absent; it also appears to play a nonessential role in the mating signal transduction pathway. The regulation of phospholipase D activity during both sporulation and mitotic growth is still not fully understood and awaits further characterization.
