Vacuolar membrane protein involved in termination of autophagy; regulates autophagy termination during persistent nitrogen starvation through Atg1p-mediated re-phosphorylation of Atg13p and PAS disassembly; type II membrane protein containing a hydrophobic transmembrane region, with N-terminal region oriented toward the cytosol and C-terminus inside the lumen; luminal domain is glycosylated; forms foci in the vacuole membrane during starvation
