## PN row 1: Autophagy-Lysosome Pathway | Pre-initiation autophagy signaling | mTORC1 pathway, upstream | Nutrient sensing | Regulator of the lysosomal v-ATPase proton pump
- UniProt: Q15904
- In branches: ALP
- Notes: Adapter protein for v-ATPase and its regulators
- PN references (titles):

- PN-node mapping records (path + ancestors):
    - [subtype] Autophagy-Lysosome Pathway|Pre-initiation autophagy signaling|mTORC1 pathway, upstream|Nutrient sensing|Regulator of the lysosomal v-ATPase proton pump
        status=mapped scope=ok_for_propagation_to_go GO=[GO:0060590 ATPase regulator activity]
        rationale: This PN leaf contains ATP6AP-family regulators of the lysosomal V-ATPase. ATPase regulator activity is the safe shared molecular-function target.
    - [type] Autophagy-Lysosome Pathway|Pre-initiation autophagy signaling|mTORC1 pathway, upstream|Nutrient sensing
        status=no_mapping scope= GO=[]
        rationale: Reviewed as a contextual PN role. The label is useful for curator triage, but by itself does not support a universal GO assertion for all member genes beyond curated ancestor or child mappings.
    - [group] Autophagy-Lysosome Pathway|Pre-initiation autophagy signaling|mTORC1 pathway, upstream
        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|Pre-initiation autophagy signaling
        status=context_only scope=too_broad_to_propagate GO=[GO:0010506 regulation of autophagy]
        rationale: This class organizes upstream signaling inputs to autophagy initiation. Because the subtree contains generic insulin, AMPK, mTORC1, nutrient-sensing, and miscellaneous signaling components, class-level propagation to regulation of autophagy would over-annotate many genes.
    - [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.

## PN row 2: Autophagy-Lysosome Pathway | Lysosomal catabolism | Regulation of lysosomal environment | Lysosomal acidification | Regulator of the lysosomal v-ATPase proton pump
- UniProt: Q15904
- In branches: ALP
- Notes: Adapter protein for v-ATPase and its regulators
- PN references (titles):
    - The emerging roles of vacuolar-type ATPase-dependent Lysosomal acidification in neurodegenerative diseases | Translational Neurodegeneration | Full Text (biomedcentral.com)
- PN-node mapping records (path + ancestors):
    - [subtype] Autophagy-Lysosome Pathway|Lysosomal catabolism|Regulation of lysosomal environment|Lysosomal acidification|Regulator of the lysosomal v-ATPase proton pump
        status=mapped scope=ok_for_propagation_to_go GO=[GO:0060590 ATPase regulator activity]
        rationale: This PN subtype is a regulator of the lysosomal V-ATPase proton pump. ATPase regulator activity is the narrowest GO target that preserves the source mechanism without requiring a speculative complex-specific term.
    - [type] Autophagy-Lysosome Pathway|Lysosomal catabolism|Regulation of lysosomal environment|Lysosomal acidification
        status=mapped scope=ok_for_propagation_to_go GO=[GO:0007042 lysosomal lumen acidification]
        rationale: This PN group directly names the lysosomal acidification mechanism. Propagation to the GO lysosomal lumen acidification term is an exact mechanistic match.
    - [group] Autophagy-Lysosome Pathway|Lysosomal catabolism|Regulation of lysosomal environment
        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|Lysosomal catabolism
        status=no_mapping scope= GO=[]
        rationale: Reviewed as a broad lysosomal-degradation container. The subtree includes carbohydrate, lipid, protein, nuclease, phosphatase, sulfatase, and environment-regulation roles, so mapping should occur at the enzyme or process subtype level.
    - [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.
