DomainThe C-terminal domain called the BARA domain is dispensable for the construction of both VPS34 PI3-kinase complexes, but is specifically required for autophagy through the targeting of complex I to the pre-autophagosomal structure. {ECO:0000269|PubMed:22437838}.
FunctionRequired for cytoplasm to vacuole transport (Cvt), autophagy, nucleophagy, and mitophagy, 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). Plays also a role in regulation of filamentous growth. {ECO:0000269|PubMed:11157979, ECO:0000269|PubMed:11689437, ECO:0000269|PubMed:12244127, ECO:0000269|PubMed:16267277, ECO:0000269|PubMed:17404498, ECO:0000269|PubMed:17700056, ECO:0000269|PubMed:18182384, ECO:0000269|PubMed:18701704, ECO:0000269|PubMed:19131141, ECO:0000269|PubMed:22437838, ECO:0000269|PubMed:8224160, ECO:0000269|PubMed:9105038, ECO:0000269|PubMed:9712845}.

Subcellular LocationEndosome membrane; Peripheral membrane protein. Vacuole membrane; Peripheral membrane protein. Preautophagosomal structure membrane; Peripheral membrane protein. Note=With the VPS34 PI3-kinase complex I, localizes to the vacuole-isolation membrane contact site (VICS) during isolation membrane (IM) expansion. The IM is a membrane sac generated from the pre-autophagosomal structure that ultimately expands to become a mature autophagosome.
