phosphatidylinositol 3-kinase complex, class III, type II phosphatidylinositol 3-kinase complex II PtdIns-3-kinase complex II GO:0034272 A class III phosphatidylinositol 3-kinase complex that is involved in vacuolar protein sorting (VPS) via endosomes. In budding yeast, this complex consists of Vps30p, Vps34p, Vps38 and Vps15p. Note that this term should not be confused with '1-phosphatidylinositol-4-phosphate 3-kinase, class IA complex; GO:0005943' or '1-phosphatidylinositol-4-phosphate 3-kinase, class IB complex ; GO:0005944'. cellular_component phosphatidylinositol 3-kinase complex, class III
