Function
Involved in autophagy and cytoplasm to vacuole transport (Cvt) vesicle formation (PubMed:8224160, PubMed:7593182, PubMed:8663607, PubMed:10735854, PubMed:14504273). Plays a key role in the organization of the preautophagosomal structure/phagophore (PAS) assembly site, the nucleating site for formation of the sequestering vesicle (PubMed:10662773, PubMed:11689437, PubMed:17329962, PubMed:17426440, PubMed:24905091). Required for mitophagy (PubMed:18818209). Cycles between the PAS and the cytoplasmic vesicle pool and may participate in supplying membrane for the growing autophagosome (PubMed:18829864, PubMed:22826123). Also involved in endoplasmic reticulum-specific autophagic process and is essential for the survival of cells subjected to severe ER stress (PubMed:17132049). Recruits vesicle-tethering proteins TRS85 and YPT1 to the autophagosome formation site (PubMed:23129774). Recruits also ATG23 and ATG8 to the PAS (PubMed:14504273).
