Abstract excerpt
Phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P(2)) is widespread in eukaryotic cells. In Saccharomyces cerevisiae, PtdIns(3,5)P(2) synthesis is catalyzed by the PtdIns3P 5-kinase Fab1p, and loss of this activity results in vacuolar morphological defects, indicating that PtdIns(3,5)P(2) is es...
