GO Term : GO:0062079 ATG2-ATG18 complex GO

Namespace  cellular_component Obsolete  false
Description  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.

Identifier Name Description
GO:0032991 protein-containing complex A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.
GO:0005737 cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
GO:0005575 cellular_component A location, relative to cellular compartments and structures, occupied by a macromolecular machine. There are three types of cellular components described in the gene ontology: (1) the cellular anatomical entity where a gene product carries out a molecular function (e.g., plasma membrane, cytoskeleton) or membrane-enclosed compartments (e.g., mitochondrion); (2) virion components, where viral proteins act, and (3) the stable macromolecular complexes of which gene product are parts (e.g., the clathrin complex).
GO:0005622 intracellular anatomical structure A component of a cell contained within (but not including) the plasma membrane. In eukaryotes it includes the nucleus and cytoplasm.
GO:0110165 cellular anatomical structure A part of a cellular organism consisting of a material entity with granularity above the level of a protein complex but below that of an anatomical system. Note that cellular organisms exclude viruses.
GO:0098796 membrane protein complex Any protein complex that is part of a membrane.
GO:0016020 membrane A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
GO:0000407 phagophore assembly site Punctate structures proximal to the endoplasmic reticulum which are the sites where the Atg machinery assembles upon autophagy induction.
GO:0034045 phagophore assembly site membrane A cellular membrane associated with the phagophore assembly site.
