## PN row 1: Translation | Cytosolic translation | Translation termination | Ribosome splitting
- UniProt: P61221
- In branches: TR
- PN-node mapping records (path + ancestors):
    - [type] Translation|Cytosolic translation|Translation termination|Ribosome splitting
        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.
    - [group] Translation|Cytosolic translation|Translation termination
        status=mapped scope=ok_for_propagation_to_go GO=[GO:0006415 translational termination]
        rationale: This PN group denotes cytosolic translation termination and release factors. Translational termination is the shared process 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: Translation | Cytosolic translation | Ribosome-associated QC | Ribosomal rescue
- UniProt: P61221
- In branches: TR
- PN-node mapping records (path + ancestors):
    - [type] Translation|Cytosolic translation|Ribosome-associated QC|Ribosomal rescue
        status=mapped scope=ok_for_propagation_to_go GO=[GO:0072344 rescue of stalled cytosolic ribosome]
        rationale: This PN RQC type denotes rescue of stalled cytosolic ribosomes. The matching GO process term is the direct 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.
