## RUBCNL
- **UniProt:** Q9H714 · **batch:** proteostasis-pr-1217 · **review status:** COMPLETE
- **PN placement:** `ALP|Autophagosome closure maturation and lysosome fusion|Class 3 PI3K complex 2, direct|Class 3 PI3K complex 2 component` ; **PN-node mapping:** `type` leaf mapped, `ok_for_propagation_to_go` → GO:0034272, goa_status `new_to_goa`; ancestors GO:0035032 / GO:0016236 context_only.
- **Consistency:** A directionality mismatch in the shared PN Notes. The PN Notes string is "Member of class III PI3K complex 2 that binds to UVRAG and inhibits activity" — copied from the Rubicon row — but RUBCNL/PACER is a POSITIVE late-autophagy regulator that stimulates Vps34 activity and recruits PI3KC3/HOPS (PMID:28306502, 30704899; UniProt). Review and notes are correct (positive); the PN workbook Notes field is wrong for this gene. Flag.
- **PN story / NEW pressure:** PN asserts GO:0034272 membership absent from GOA (`new_to_goa`). Review adds GO:0034272 part_of as action NEW (PMID:28306502), plus GO:0030674 protein-macromolecule adaptor activity (NEW) replacing generic protein binding. GO:0034272 verified real. Verdict: ADD GO:0034272 (review already did) + adaptor MF — aligned with and richer than PN.
- **Mapping strategy:** Supports (does not change) the C2-component → GO:0034272 mapping. As with RUBCN, PACER recruits/associates with PI3KC3-C2 rather than being a defined stoichiometric subunit, so `part_of` is defensible but borderline (review flags this in suggested_questions). PN-projected term coincides with the review's NEW term.
- **Evidence alignment:** Divergence. PN cites Annual Review, a cardiovascular review, and PMID:19270696 (the Atg14L/Rubicon paper) — none of which is PACER-specific; PMID:19270696 is not cited in the RUBCNL review (and is not PACER-relevant). Review uses the correct primary literature: PMID:28306502 (PACER discovery), 30704899 (mTORC1/TIP60). PN reference set is essentially a shared-branch boilerplate, weakly matched to this gene.
- **Verdict:** Consistent on biology, but the PN workbook Notes mis-state PACER as inhibitory ("inhibits activity") — it is a positive regulator. NEW GO:0034272 matches PN projection (verified). **Recommended edits:** none to the gene YAML (correct); upstream PN-workbook Notes for RUBCNL should be corrected from "inhibits activity" to a positive/recruitment role, and the PN reference list (PMID:19270696) is not PACER-specific.
