Phosphatidylinositol phosphates are key regulators of vesicle identity, formation and trafficking. In mammalian cells, the evolutionarily conserved class III PtdIns 3-kinase PIK3C3/VPS34 is part of a large multiprotein complex that catalyzes the localized phosphorylation of phosphatidylinositol to phosphatidylinositol-3-phosphate (PtdIns3P). We demonstrate that PIK3C3 has a key function in vesicular trafficking, endocytosis and autophagosome-autolysosome formation in the highly specialized glomerular podocytes.
