PN-node mapping records (path + ancestors):
[subtype] Autophagy-Lysosome Pathway|Autophagy substrate selection|Marking substrates for selective autophagy|Mitophagy|PINK/PRKN pathway
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.
[type] Autophagy-Lysosome Pathway|Autophagy substrate selection|Marking substrates for selective autophagy|Mitophagy
status=mapped scope=ok_for_propagation_to_go GO=[GO:0000423 mitophagy]
rationale: The PN marking category for mitophagy captures upstream cargo-marking steps that commit mitochondrial substrates to the mitophagy pathway. That supports propagation to mitophagy.
[group] Autophagy-Lysosome Pathway|Autophagy substrate selection|Marking substrates for selective autophagy
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|Autophagy substrate selection
status=no_mapping scope= GO=[]
rationale: Reviewed as a broad substrate-selection container. GO has useful targets for specific receptor, cargo-adaptor, and selective-autophagy leaves, but this class mixes marking, recognition, receptor regulation, and unknown roles and should not propagate as one term.
[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-node mapping records (path + ancestors):
[subtype] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|RING|SIAH / SINA|SIA TRAF-like
status=no_mapping scope= GO=[]
rationale: Reviewed as a narrower E3-ligase architecture, component, or domain subdivision already covered by the curated parent E3 mapping. No additional direct GO mapping is needed at this node.
[type] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|RING|SIAH / SINA
status=no_mapping scope= GO=[]
rationale: Reviewed as a narrower E3-ligase architecture, component, or domain subdivision already covered by the curated parent E3 mapping. No additional direct GO mapping is needed at this node.
[group] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|RING
status=mapped scope=ok_for_propagation_to_go GO=[GO:0061630 ubiquitin protein ligase activity]
rationale: This PN group is a catalytic ubiquitin E3 ligase bucket. The shared GO molecular-function target is ubiquitin protein ligase activity.
[class] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases
status=context_only scope=too_broad_to_propagate GO=[GO:0061630 ubiquitin protein ligase activity]
rationale: This class is a genuine E3-ligase context, but its descendants include catalytic ligases, cullin scaffolds, substrate receptors, adaptors, cofactors, regulators, and UBL modifier systems. A class-level propagation would over-annotate.
[branch] Ubiquitin Proteasome System
status=no_mapping scope= GO=[]
rationale: Reviewed as the top-level UPS branch. It is a project taxonomy umbrella rather than a direct GO assertion; UPS propagation must come from manually curated child nodes.
