Consistency: Strong agreement. Notes, review YAML and PN annotation all describe a cytosolic class-B HSP40 that stimulates HSP70 (HSPA1A/B) ATPase and delivers misfolded clients. No contradictions; PN "J-domain HSP70 cochaperone" type matches the gene's verified core MF.
PN story / NEW pressure: PN asserts direct HSP70 interaction. This is already captured experimentally: GO:0001671 ATPase activator activity (IDA, PMID:24318877, ACCEPT/core) and GO:0051087 protein-folding chaperone binding (IPI PMID:21231916, ACCEPT/core). The PN-projected GO:0030544 "Hsp70 protein binding" (verified real via OLS) is a child of GO:0051087 — i.e. it would be a more specific refinement, not a missing function. No NEW-term pressure; the muscle/Z-disc role (GO:0030018 IDA) is also well captured. Verdict: already captured (GO:0030544 is a defensible specialization).
Mapping strategy: Node already mapped to GO:0030544 (correct, narrower than the gene's GO:0051087). Status/scope appropriate — DNAJB4 has direct IPI HSP70-binding evidence, so it genuinely supports the type-level mapping rather than over-reaching. Parent no_mapping decisions are sound.
Evidence alignment: PN reference titles overlap the review's core PMIDs (21231916 HSP70 machine; 24318877 NEF/ATPase; 36264506 myopathy/Z-disc). No divergence.
Verdict: CONSISTENT — PN GO:0030544 is a defensible narrower specialization of the gene's experimentally-supported GO:0051087/GO:0001671 HSP70-cochaperone MF; node mapping correct.
