An autophagy assay reveals the ESCRT-III component CHMP2A as a regulator of phagophore closure | Nature Communications
PN-node mapping records (path + ancestors):
[type] Autophagy-Lysosome Pathway|Autophagosome closure maturation and lysosome fusion|Sealing of autophagophore membrane|ESCRT-III complex activity modulator
status=context_only scope=too_broad_to_propagate GO=[GO:0000815 ESCRT III complex]
rationale: Reviewed as an ESCRT-III activity modulator. It is related to ESCRT-III but should not project ESCRT-III complex membership to all members.
[group] Autophagy-Lysosome Pathway|Autophagosome closure maturation and lysosome fusion|Sealing of autophagophore membrane
status=mapped scope=ok_for_propagation_to_go GO=[GO:0000045 autophagosome assembly]
rationale: This group captures autophagophore closure/sealing, a late step in autophagosome assembly. Autophagosome assembly is the safer process target than autophagosome-lysosome fusion.
[class] Autophagy-Lysosome Pathway|Autophagosome closure maturation and lysosome fusion
status=context_only scope=too_broad_to_propagate GO=[GO:0016236 macroautophagy]
rationale: This class is a late macroautophagy context, but the subtree mixes docking, fusion, localization, membrane-composition, and unknown late-stage roles. The class-level relation is useful for display while propagation is restricted to narrower mechanism nodes.
[branch] Autophagy-Lysosome Pathway
status=no_mapping scope= GO=[]
rationale: Reviewed as the top-level PN branch. It is a project taxonomy umbrella rather than a direct GO assertion; all propagation must come from manually curated child nodes.
[type] Autophagy-Lysosome Pathway|Microautophagy|General microautophagy machinery|ESCRT-III complex component
status=mapped scope=ok_for_propagation_to_go GO=[GO:0000815 ESCRT III complex]
rationale: This leaf is a component bucket for ESCRT-III machinery used in microautophagy contexts. The shared GO assertion is ESCRT III complex membership.
[group] Autophagy-Lysosome Pathway|Microautophagy|General microautophagy machinery
status=no_mapping scope= GO=[]
rationale: Reviewed as a broad PN taxonomy container. The descendants mix components, regulators, context labels, and mechanistic leaves, so propagation should come only from narrower curated nodes.
[class] Autophagy-Lysosome Pathway|Microautophagy
status=context_only scope=too_broad_to_propagate GO=[GO:0016237 microautophagy]
rationale: The class names a real GO process, but the subtree includes machinery components and mitochondrion-derived-vesicle contexts as well as process labels. Propagation is restricted to narrower nodes.
[branch] Autophagy-Lysosome Pathway
status=no_mapping scope= GO=[]
rationale: Reviewed as the top-level PN branch. It is a project taxonomy umbrella rather than a direct GO assertion; all propagation must come from manually curated child nodes.
