PN placement:ER proteostasis|Protein transport|Signal recognition particle component ; PN-node mapping: group=mapped scope=ok_for_propagation_to_go→GO:0006614 (SRP-dependent cotranslational protein targeting to membrane); class Protein transport=mapped→GO:0015031; branch=no_mapping.
Consistency: Strong and mutually consistent. Deep research, review YAML, and PN annotation all describe SRP72 as the largest SRP subunit, an RNA-binding scaffold that heterodimerizes with SRP68 (N-terminal TPR), threads along the 7SL 5e/5f loops, and contributes to ribosome contacts. The PN "SRP component" label and GO:0006614 mapping match the review's core BP (GO:0006614 IBA/IEA, ACCEPT). No contradictions.
PN story / NEW pressure: PN asserts only the canonical SRP cotranslational-targeting role, already captured (GO:0006614, GO:0008312 7S RNA binding, GO:0005047 SRP binding, GO:0043022 ribosome binding, GO:0005786 SRP membership). The BMFS1 disease link (PMID:22541560) and nucleolar/Cajal-body assembly pool (PMID:38858088) are in the review but outside the PN story. Conclusion: already captured (no NEW pressure).
Mapping strategy: No change needed. GO:0006614 (goa_status already_in_goa_exact) is present and ACCEPTed — exact projection, not broader than the review. The class-level GO:0015031 is a broad class target, not asserted of SRP72.
Evidence alignment: PN dossier lists no reference titles; alignment via projected-term provenance. Review's core support (PMID:27899666 definitive SRP72 structures; PMID:28369529 apo/SRP68-72 structures; PMID:17254600 RNA-remodeling assembly; PMID:16672232 SRP68-binding TPR; PMID:34208095 SRP review) all encode the SRP cotranslational-targeting biology the PN maps to. No divergence.
