PN placement:ER proteostasis|Protein transport|GET pathway component ; PN-node mapping: group → GO:0006620 (post-translational protein targeting to ER membrane), scope=ok_for_propagation, goa_status=more_specific_than_existing_goa; class → GO:0015031 (protein transport); branch=no_mapping.
Consistency: Deep research (notes + falcon), review YAML, and PN annotation are consistent: GET1/WRB is the ER membrane receptor-insertase subunit of the GET pathway, with CAMLG/GET2 forming the heterotetramer that accepts GET3-delivered TA proteins. Distinction "receptor/insertase (GET1) vs ATPase targeting factor (GET3)" is honored. The review correctly MARK_AS_OVER_ANNOTATED the legacy nucleus TAS (PMID:9544840), not reproduced.
PN story / NEW pressure: PN asserts post-translational ER-membrane targeting/insertion of TA proteins — already captured by review's core terms GO:0071816 (TA insertion into ER membrane), GO:0045048 (protein insertion into ER membrane), GO:0043495 (protein-membrane adaptor activity, the PAN-GO MF), GO:0043529 (GET complex). No NEW GO term warranted; already captured.
Mapping strategy:GET1 does not alter the GET-node mapping. Discrepancy flag:GET1 dossier labels GO:0006620more_specific_than_existing_goa whereas the identical GET3 mapping labels it new_to_goa — one is wrong (GET1's GOA carries the insertion terms but not GO:0006620 specifically; both genes should share the same goa_status for the same projected term). GO:0006620 is verified-real and a defensible group term, but is a targeting (not insertion) term; GET1's role is the membrane receptor-insertase, so GO:0006620 is slightly off-target for GET1 specifically (better fits GET3). Acceptable as a group/pathway-level term, but narrower-fit for GET3 than GET1.
Evidence alignment: Strong overlap — review's GET-pathway PMIDs (21444755, 23041287, 27226539, 32910895, 36640319, 37963916) fully support the PN targeting/insertion claim.
Verdict: Consistent; well-reviewed. Flag the GO:0006620 goa_status inconsistency between GET1 (more_specific_than_existing_goa) and GET3 (new_to_goa) dossiers and that GO:0006620 (targeting) fits GET3 better than the receptor-insertase GET1.
