Notes: Receptor for selective autophagy. Normally acts as a prominent inhibitor of bulk autophagy via stabilizing interactions between autophagy factor Beclin1 and anti-autophagy Mcl-1. TRIM17 is specifically required for the promotion and the removal of midbodies, remnants of the cell division machinery that are known autophagy targets via its interaction with p62/SQSTM1 and LC3B.

TRIM17 contributes to autophagy of midbodies while actively sparing other targets from degradation

[type] Autophagy-Lysosome Pathway|Autophagy substrate selection|Selective autophagy receptor|Midbody autophagy
status=mapped scope=ok_for_propagation_to_go GO=[GO:0160247 autophagy cargo adaptor activity]
rationale: Midbody-autophagy receptors such as SQSTM1 link ubiquitinated midbody material to the autophagy machinery. GO does not currently expose a dedicated midbody-autophagy process term in the local ontology cache, so the receptor activity term is the best available mapping target.
[group] Autophagy-Lysosome Pathway|Autophagy substrate selection|Selective autophagy receptor
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|Autophagy substrate selection
status=no_mapping scope= GO=[]
rationale: Reviewed as a broad substrate-selection container. GO has useful targets for specific receptor, cargo-adaptor, and selective-autophagy leaves, but this class mixes marking, recognition, receptor regulation, and unknown roles and should not propagate as one term.
[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.

PN-node mapping records (path + ancestors):
[subtype] Ubiquitin Proteasome System|E3 ubiquitin and UBL ligases|RING|TRIM / class IV|SPRY
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|RING|TRIM / class IV
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|RING
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.
