PN row 1: ER proteostasis | Protein transport | GET pathway component
UniProt: O00258
In branches: ER
PN-node mapping records (path + ancestors):
[group] ER proteostasis|Protein transport|GET pathway component
status=mapped scope=ok_for_propagation_to_go GO=[GO:0006620 post-translational protein targeting to endoplasmic reticulum membrane]
rationale: The PN GET-pathway group covers machinery for post-translational delivery of tail-anchored membrane proteins to the ER. GO does not model the GET pathway directly in the local cache, and the closest supported process term is post-translational targeting to the ER membrane.
[class] ER proteostasis|Protein transport
status=mapped scope=ok_for_propagation_to_go GO=[GO:0015031 protein transport]
rationale: The PN ER Protein transport class groups ER-targeting and ER-insertion pathways. GO protein transport is the appropriate propagation target, while the source class remains ER-specific and broader than any single GO transport subtype.
[branch] ER proteostasis
status=no_mapping scope= GO=[]
rationale: Reviewed as a top-level PN branch. This is a systems/taxonomy umbrella, not a direct GO assertion; narrower child curations carry any propagating GO mappings.
