PN row 1: Autophagy-Lysosome Pathway | Pre-initiation autophagy signaling | mTORC1 pathway, direct | Modulator of mTORC1 activity
UniProt: Q969H0
In branches: ALP, UPS
Notes: F-box protein, member of SCF E3 ubiquitin ligase. Mediates ubiquitination and thereby degradation of SHOC2, which binds and activates RPTOR to inhibit mTORC1, thereby activating mTORC1 and suppressing autophagy.

PN-node mapping records (path + ancestors):
[type] Autophagy-Lysosome Pathway|Pre-initiation autophagy signaling|mTORC1 pathway, direct|Modulator of mTORC1 activity
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, direct
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: Ubiquitin Proteasome System | E3 ubiquitin and UBL ligases | Cul1 substrate receptor | F-box | WD40

PN-node mapping records (path + ancestors):
[subtype] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|Cul1 substrate receptor|F-box|WD40
status=no_mapping scope= GO=[]
rationale: Reviewed as a narrower substrate-receptor, adaptor, domain, or family subdivision already covered by the curated parent adaptor/receptor mapping. No additional direct GO mapping is needed at this node.
[type] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|Cul1 substrate receptor|F-box
status=no_mapping scope= GO=[]
rationale: Reviewed as a narrower substrate-receptor, adaptor, domain, or family subdivision already covered by the curated parent adaptor/receptor mapping. No additional direct GO mapping is needed at this node.
[group] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|Cul1 substrate receptor
status=mapped scope=ok_for_propagation_to_go GO=[GO:1990756 ubiquitin-like ligase-substrate adaptor activity]
rationale: This PN group captures substrate receptors/adaptors for cullin/UBL ligase systems. The shared GO molecular-function target is ubiquitin-like ligase-substrate adaptor 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.

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.
[subtype] Ubiquitin Proteasome System|Ubiquitin and UBL binding|E3 ligase|CUL1 receptor|idiosyncratic Ub binding / WD40
status=no_mapping scope= GO=[]
rationale: Reviewed as a narrower enzyme-family, domain, or architecture subdivision already covered by a curated parent enzyme mapping. No additional direct GO mapping is needed at this node.
[type] Ubiquitin Proteasome System|Ubiquitin and UBL binding|E3 ligase|CUL1 receptor

[group] Ubiquitin Proteasome System|Ubiquitin and UBL binding|E3 ligase
status=mapped scope=ok_for_propagation_to_go GO=[GO:0061630 ubiquitin protein ligase activity]
rationale: This PN group captures ubiquitin/UBL-binding factors that are E3 ligases. The shared molecular-function target is ubiquitin protein ligase activity.
[class] Ubiquitin Proteasome System|Ubiquitin and UBL binding
status=context_only scope=too_broad_to_propagate GO=[GO:0140036 ubiquitin-modified protein reader activity]
rationale: This class records ubiquitin/UBL-reader context, but the subtree mixes ubiquitin, SUMO, UBL-domain, domain-architecture, catalytic, signaling, trafficking, and nucleic-acid process buckets. It is useful context, not a safe direct propagation.
