[subtype] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|idiosyncratic UBOX complex|STUB1/CHIC2 complex|noncatalytic
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 UBOX complex|STUB1/CHIC2 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 UBOX 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.
