PN placement:ER proteostasis | Maturation and folding of specific substrates | ER collagen processing and folding ; PN-node mapping: group=mapped, scope=ok_for_propagation_to_go, GO:0032964 collagen biosynthetic process (class/branch ancestors = no_mapping)
Consistency: Fully consistent. Deep-research notes, review YAML, PN annotation, and PN-node mapping all describe CRTAP as the non-catalytic scaffolding subunit of the ER collagen prolyl 3-hydroxylation complex (with P3H1/PPIB) that 3-hydroxylates α1(I)/α1(II) Pro986 and acts as a collagen foldase. No contradictions.
PN story / NEW pressure: PN asserts collagen biosynthetic context. This is already captured: the review explicitly lists GO:0032964 collagen biosynthetic process in core_functions.directly_involved_in, and the GOA carries collagen-fibril-organization / protein-folding-in-ER terms. GO:0032964 verified real via OLS. No NEW-term pressure beyond what the review already proposes (MODIFY protein folding → GO:0034975; collagen complex CC term flagged as a suggested question). Conclusion: already captured.
Mapping strategy: No change needed. The group-node mapping to GO:0032964 is defensible and matches the review's own process annotation; ancestor nodes correctly left no_mapping. Projected term is the same grain as the review (neither broader nor narrower). Consistent with the project's pattern of mapping only the substrate-specific group node.
Evidence alignment: Strong overlap. PN dossier carries no reference titles for this row, but the review's collagen-process evidence (PMID:19846465, PMID:20089953, PMID:39245686, Reactome collagen reactions) directly underpins the GO:0032964 mapping. No divergence.
Verdict: Consistent; PN role already captured in review (GO:0032964). No edits required.
