## CSNK1D
- **UniProt:** P48730 · **batch:** proteostasis-batch-2026-06-07 · **review status:** COMPLETE
- **PN placement:** row1 `ALP|Autophagophore initiation and elongation|Regulation of autophagophore membrane composition|ER membrane input|COPII vesicle component regulator`; row2 `ALP|Autophagosome closure maturation and lysosome fusion|Sealing of autophagophore membrane|...unknown` ; **PN-node mapping:** Sealing group→GO:0000045 autophagosome assembly (new_to_goa); all other ALP nodes no_mapping; ALP class context_only→GO:0016236.
- **Consistency:** GAP. The review treats CK1δ's COPII/SEC23 phosphorylation (Reactome GO:0048208 COPII vesicle coat assembly; R-HSA-5694441) as a generic, non-core **secretory** role and has NO autophagy annotation — it never mentions RAB1-directed autophagosome closure or COPII-regulated autophagophore membrane input. The PN frames the SAME COPII/RAB1 biology as autophagy-directed (RAB1 effector → phosphorylates COPII coat → autophagosome closure), citing CK1δ/Hrr25 autophagosome-completion papers absent from the review. So review and PN are not contradictory but interpret overlapping evidence (Golgi/COPII/RAB1) in different pathways; the autophagy reading is under-captured in the review.
- **PN story / NEW pressure:** PN asserts an autophagosome-closure/sealing role not in existing GO or the review. GO:0000045 "autophagosome assembly" verified real (OLS) and confirmed new_to_goa (no autophagy term in CSNK1D-goa.tsv). Defensible **ADD** if the Hrr25/CK1δ autophagosome-completion literature (Frontiers/JCB titles in PN row) holds for human CK1δ — but PN supplies only article titles, not verified PMIDs; much of the primary evidence is yeast Hrr25. Treat as defensible-but-needs-PMID-verification.
- **Mapping strategy:** GO:0000045 from the "Sealing of autophagophore membrane" group is appropriately specific (assembly, not autophagosome-lysosome fusion); the "unknown" leaf and COPII-regulator leaf are correctly no_mapping. Reasonable; not over-broad.
- **Evidence alignment:** No overlap. PN cites autophagosome-closure review + Ypt1/Rab1-Hrr25 JCB + CK1δ/Hrr25 autophagosome-completion Frontiers (titles only). Review cites COPII via Reactome (R-HSA-204005, R-HSA-5694441) only, framed as secretory. The autophagy PMIDs are missing from the review.
- **Verdict:** UNDER-CAPTURED autophagy role; PN ADD (GO:0000045) plausible but PMID-unverified. **Recommended edits:** [REF] resolve the PN row's title-only citations to PMIDs and confirm human (not just yeast Hrr25) evidence; [YAML] if confirmed, add GO:0000045 (involved_in) and reframe the SEC23/COPII annotations to note an autophagosome-membrane-input role alongside secretion.
