PN row 1: ER proteostasis | Organelle-specific protein degradation | ER associated degradation | ER handling of ERAD substrates
UniProt: O75477
In branches: ER, UPS
PN-node mapping records (path + ancestors):
[type] ER proteostasis|Organelle-specific protein degradation|ER associated degradation|ER handling of ERAD substrates
status=mapped scope=ok_for_propagation_to_go GO=[GO:0036503 ERAD pathway]
rationale: This PN type captures ER-lumenal and membrane-local ERAD handling steps prior to retrotranslocation. These steps are mechanistic parts of the broader ERAD pathway, so propagation to ERAD pathway is appropriate.
[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.
PN row 2: Ubiquitin Proteasome System | E3 ubiquitin and UBL ligases | idiosyncratic RING complex | RNF170 / ERLIN complex | noncatalytic / BAND 7
UniProt: O75477

PN-node mapping records (path + ancestors):
[subtype] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|idiosyncratic RING complex|RNF170 / ERLIN complex|noncatalytic / BAND 7
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|idiosyncratic RING complex|RNF170 / ERLIN complex
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|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]
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.
