CC -!- FUNCTION: Required for cytoplasm to vacuole transport (Cvt), pexophagy
CC and mitophagy. Also involved in endoplasmic reticulum-specific
CC autophagic process and is essential for the survival of cells subjected
CC to severe ER stress. Functions in protein retrieval from the endocytic
CC pathway. Required for proper sorting of the v-SNARE protein SNC1.
CC {ECO:0000269|PubMed:12048214, ECO:0000269|PubMed:12554655,
CC ECO:0000269|PubMed:15901835, ECO:0000269|PubMed:16138904,

CC ECO:0000269|PubMed:20861302}.
CC -!- SUBUNIT: Forms a complex with SNX4 and ATG17.
CC -!- INTERACTION:
CC Q07528; P47057: SNX4; NbExp=7; IntAct=EBI-36894, EBI-17610;
CC Q07528; P53039: YIP1; NbExp=2; IntAct=EBI-36894, EBI-25295;
CC -!- SUBCELLULAR LOCATION: Endosome membrane; Peripheral membrane protein.
CC Preautophagosomal structure membrane; Peripheral membrane protein.
CC -!- DOMAIN: The PX domain binds phosphatidylinositol 3-phosphate which is
CC necessary for peripheral membrane localization of ATG20 to the
CC perivacuolar punctate structures.
CC -!- MISCELLANEOUS: Present with 358 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the sorting nexin family. {ECO:0000305}.
