## PN row 1: Autophagy-Lysosome Pathway | Autophagosome closure maturation and lysosome fusion | Sealing of autophagophore membrane | ESCRT-I complex component
- UniProt: A5D8V6
- In branches: ALP
- Notes: Component of the ESCRT-I complex, involved in autophagosome closure

    - A helical assembly of human ESCRT-I scaffolds reverse-topology membrane scission | Nature Structural & Molecular Biology
- PN-node mapping records (path + ancestors):
    - [type] Autophagy-Lysosome Pathway|Autophagosome closure maturation and lysosome fusion|Sealing of autophagophore membrane|ESCRT-I complex component
        status=mapped scope=ok_for_propagation_to_go GO=[GO:0000813 ESCRT I complex]
        rationale: This leaf is restricted to ESCRT-I components used in autophagophore sealing. The shared GO assertion is ESCRT I complex membership.
    - [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.
