[type] Translation|Cytosolic translation|Ribosome biogenesis factor|pre-40S complex
status=mapped scope=ok_for_propagation_to_go GO=[GO:0030688 preribosome, small subunit precursor]
rationale: This PN type denotes pre-40S particles. The GO preribosome small-subunit precursor term is the direct complex target.
[group] Translation|Cytosolic translation|Ribosome biogenesis factor
status=mapped scope=ok_for_propagation_to_go GO=[GO:0042254 ribosome biogenesis]
rationale: This PN group collects factors assigned through cytosolic ribosome biogenesis, including SSU-processosome and pre-60S maturation machinery. The full PN path resolves the earlier over-annotation problem: these genes are not being placed by core translational elongation or decoding, but by assembly and maturation of ribosomal subunits. GO ribosome biogenesis is therefore the appropriate propagation 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.
[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.
PN row 3: Autophagy-Lysosome Pathway | Autophagophore initiation and elongation | ATG8 homolog processing, upstream | Preparation of ATG8 homologs for lipidation | Modulation of ATG5-ATG12-ATG16 complex activity
UniProt: P63244
In branches: TR, ALP
Notes: RACK1 interacts with ATG5. Importantly, classical autophagy inducers (starvation or mammalian target of rapamycin blockage) stimulated RACK1-ATG5 interaction. Knockdown of RACK1 or prevention of its binding to ATG5 using mutagenesis blocked autophagy activation. RACK1 may recruit other proteins to the phagophore membrane.

[subtype] Autophagy-Lysosome Pathway|Autophagophore initiation and elongation|ATG8 homolog processing, upstream|Preparation of ATG8 homologs for lipidation|Modulation of ATG5-ATG12-ATG16 complex activity
status=no_mapping scope= GO=[]
rationale: This PN leaf is a regulator bucket rather than a shared gene function or shared process participation class. The current gene set is too heterogeneous for a single defensible GO target.
[type] Autophagy-Lysosome Pathway|Autophagophore initiation and elongation|ATG8 homolog processing, upstream|Preparation of ATG8 homologs for lipidation
status=no_mapping scope= GO=[]
rationale: Reviewed as a contextual PN role. The label is useful for curator triage, but by itself does not support a universal GO assertion for all member genes beyond curated ancestor or child mappings.
[group] Autophagy-Lysosome Pathway|Autophagophore initiation and elongation|ATG8 homolog processing, upstream
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|Autophagophore initiation and elongation
status=context_only scope=too_broad_to_propagate GO=[GO:0016236 macroautophagy]
rationale: This class is a real macroautophagy context, but its descendants include core factors, component buckets, upstream modulators, localization roles, and residual categories. Projecting generic macroautophagy from this ancestor creates TRAPP-like overpropagation, so candidate GO annotations must come from narrower curated nodes.
[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.
