PN row 1: ER proteostasis | Organelle-specific protein degradation | ER associated degradation | Cytosolic handling of ERAD substrates | ERAD-associated RING E3 ligase
UniProt: Q96GF1
In branches: ER, ALP, UPS
PN-node mapping records (path + ancestors):
[subtype] ER proteostasis|Organelle-specific protein degradation|ER associated degradation|Cytosolic handling of ERAD substrates|ERAD-associated RING E3 ligase
status=mapped scope=ok_for_propagation_to_go GO=[GO:0061630 ubiquitin protein ligase activity]
rationale: This PN subtype denotes ERAD-associated RING E3 ligases. Ubiquitin protein ligase activity is the appropriate shared catalytic target.
[type] ER proteostasis|Organelle-specific protein degradation|ER associated degradation|Cytosolic handling of ERAD substrates
status=mapped scope=ok_for_propagation_to_go GO=[GO:0036503 ERAD pathway]
rationale: This PN type covers the cytosolic processing steps that receive ERAD substrates after retrotranslocation. These activities remain part of the ERAD pathway, but the source category is a specific mechanistic slice.
[group] ER proteostasis|Organelle-specific protein degradation|ER associated degradation
status=mapped scope=exact GO=[GO:0036503 ERAD pathway]
rationale: The PN group "ER associated degradation" is a direct lexical and biological match to the GO ERAD pathway term. The additional branch and class context disambiguates the source string from any broader degradation language.
[class] ER proteostasis|Organelle-specific protein degradation
status=no_mapping scope= GO=[]
rationale: Reviewed as a broad PN category rather than a single GO class. The member genes span multiple activities, complexes, or contexts, so direct propagation from this node would overstate the shared biology.
[branch] ER proteostasis
status=no_mapping scope= GO=[]
rationale: Reviewed as a top-level PN branch. This is a systems/taxonomy umbrella, not a direct GO assertion; narrower child curations carry any propagating GO mappings.
Notes: Mitochondrial ubiquitin E3 ligase that regulates selective mitochondrial autophagy via interaction with BNIP1.

[type] Autophagy-Lysosome Pathway|Autophagy substrate selection|Autophagy receptor regulation|Mitophagy
status=mapped scope=ok_for_propagation_to_go GO=[GO:0000423 mitophagy]
rationale: The PN receptor-regulation type for mitophagy captures factors that tune receptor activity within the mitophagy pathway. This supports propagation to mitophagy while preserving that the source is a regulatory sub-role.
[group] Autophagy-Lysosome Pathway|Autophagy substrate selection|Autophagy receptor regulation
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 row 3: Ubiquitin Proteasome System | E3 ubiquitin and UBL ligases | RING | with transmembrane domain | ER, mitochondria
UniProt: Q96GF1
In branches: ER, ALP, UPS
Signature domains: IPR001841
Auxiliary domains: (none)

PN-node mapping records (path + ancestors):
[subtype] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|RING|with transmembrane domain|ER, mitochondria
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|with transmembrane domain
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.

[group] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|idiosyncratic RING complex
status=mapped scope=ok_for_propagation_to_go GO=[GO:0000151 ubiquitin ligase complex]
rationale: This PN group is an E3 ligase complex bucket. The safest shared GO target is ubiquitin ligase complex membership rather than assigning catalytic activity to every subunit.
[class] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases
status=context_only scope=too_broad_to_propagate GO=[GO:0061630 ubiquitin protein ligase activity]
