CC -!- FUNCTION: Lipid transfer protein involved in autophagosome assembly
CC (PubMed:28561066, PubMed:31271352, PubMed:30952800). Tethers the edge
CC of the isolation membrane (IM) to the endoplasmic reticulum (ER) and
CC mediates direct lipid transfer from ER to IM for IM expansion
CC (PubMed:31271352, PubMed:30952800). Binds to the ER exit site (ERES),
CC which is the membrane source for autophagosome formation, and extracts
CC phospholipids from the membrane source and transfers them to ATG9
CC (ATG9A or ATG9B) to the IM for membrane expansion (PubMed:31271352,
CC PubMed:30952800). Lipid transfer activity is enhanced by WIPI1 and
CC WDR45/WIPI4, which promote ATG2A-association with phosphatidylinositol
CC 3-monophosphate (PI3P)-containing membranes (PubMed:31271352). Also
CC regulates lipid droplets morphology and distribution within the cell
CC (PubMed:22219374, PubMed:28561066). {ECO:0000269|PubMed:22219374,
