PN row 1: Translation | Cytosolic translation | Ribosome-associated QC | ubiquitination of eEF1A on stalled ribosomes
UniProt: Q9UBS8
In branches: TR, UPS
PN-node mapping records (path + ancestors):
[type] Translation|Cytosolic translation|Ribosome-associated QC|ubiquitination of eEF1A on stalled ribosomes
status=mapped scope=ok_for_propagation_to_go GO=[GO:0016567 protein ubiquitination]
rationale: This PN RQC type is a specific ubiquitination bucket for eEF1A on stalled ribosomes. Protein ubiquitination is the shared process target.
[group] Translation|Cytosolic translation|Ribosome-associated QC
status=mapped scope=ok_for_propagation_to_go GO=[GO:0006515 protein quality control for misfolded or incompletely synthesized proteins]
rationale: The PN ribosome-associated quality-control group covers surveillance and disposal of stalled or defective nascent-chain translation products. GO lacks a dedicated ribosome-associated QC term in the local cache, so the broader protein-quality-control process is the best supported target.
[class] Translation|Cytosolic translation
status=context_only scope=too_broad_to_propagate GO=[GO:0002181 cytoplasmic translation]
rationale: The PN class Cytosolic translation is centered on the cytoplasmic translation apparatus and process, but it also houses supporting machinery such as ribosome biogenesis factors. The GO process term is a useful high-level label for the class, but propagating it to all members would over-annotate genes whose PN placement is through assembly or maturation context rather than core cytoplasmic translation.
[branch] Translation
status=context_only scope=too_broad_to_propagate GO=[GO:0006412 translation]
rationale: The PN Translation branch is organized around the translation apparatus and immediately associated cotranslational quality-control systems. GO translation is the closest high-level process label, but the PN branch also contains adjacent machinery such as ribosome biogenesis and nascent-chain handling. Keeping this relationship is useful for interpretation, but it is too broad to project safely onto every member.
PN row 2: Ubiquitin Proteasome System | E3 ubiquitin and UBL ligases | RBR | RWD

PN-node mapping records (path + ancestors):
[type] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|RBR|RWD
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|RBR
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.
PN row 3: Ubiquitin Proteasome System | Ubiquitin and UBL binding | E3 ligase | RBR / with UBD | RWD
UniProt: Q9UBS8
In branches: TR, UPS
Signature domains: IPR006575
Auxiliary domains: IPR044066
PN-node mapping records (path + ancestors):
[subtype] Ubiquitin Proteasome System|Ubiquitin and UBL binding|E3 ligase|RBR / with UBD|RWD
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|RBR / with UBD
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.
[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.
[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.
