General FunctionInvolved in binding
Specific FunctionPhosphatidylinositol 3-kinase required for cytoplasm to vacuole transport (Cvt) and autophagy as a part of the autophagy- specific VPS34 PI3-kinase complex I. This complex is essential to recruit the ATG8-phosphatidylinositol conjugate and the ATG12-ATG5 conjugate to the pre-autophagosomal structure. Also involved in endosome-to-Golgi retrograde transport as part of the VPS34 PI3- kinase complex II. This second complex is required for the endosome-to-Golgi retrieval of PEP1 and KEX2, and the recruitment of VPS5 and VPS7, two components of the retromer complex, to endosomal membranes (probably through the synthesis of a specific pool of phosphatidylinositol 3-phosphate recruiting the retromer to the endosomes). Its activation by VPS15 may lead to the phosphorylation of phosphatidylinositol in the sorting compartment membrane. Finally, it might also be involved in ethanol tolerance and cell wall integrity
Cellular LocationGolgi apparatus, trans-Golgi network membrane; Peripheral membrane protein. Endosome membrane; Peripheral membrane protein
