General Information
Term ATG2-ATG18 complex ID (Ontology) GO:0062079 (Gene Ontology)
Definition A protein complex essential for autophagy during nutrient deprivation, a catabolic process that sequesters undesired cellular material into autophagosomes for delivery to lysosomes for degradation. Contributes to nutrition homeostasis and damage control in eukaryotic cells. Functions at a late step of autophagosome formation for efficient completion of sequestration, probably through facilitating recruitment of ATG8-phosphatidylethanolamine (PE) to the preautophagosomal structure (PAS) and/or its protection from deconjugation by ATG4. Composed of ATG2 and ATG18 in Saccharomyces cerevisiae.[ PubMed:23230146 ]
