Consistency: Consistent. Notes, review, and PN agree SH3GLB1/Bif-1/endophilin B1 is a POSITIVE N-BAR/SH3 adaptor that activates PI3KC3 via UVRAG (PMID:17891140) and drives ATG9/Golgi membrane fission (PMID:21068542). PN Notes ("binds to UVRAG and promotes activity") correctly state the positive direction — contrast with the RUBCNL row, which was mislabeled. No contradictions.
PN story / NEW pressure: PN asserts GO:0034272 membership. GOA has only generic GO:0032991 (protein-containing complex, IDA+IEA), so GO:0034272 is more_specific_than_existing_goa. Review handles this via MODIFY of GO:0032991 → proposed_replacement GO:0034272 (rather than a standalone NEW row). GO:0034272 verified real. Review also adds membrane-fission (GO:0090148) and positive regulation of membrane tubulation (GO:1903527) as core — both verified real, non-obsolete, and beyond the PN story. Verdict: ADD/refine to GO:0034272 (review does via MODIFY) — aligned with PN.
Mapping strategy: Supports the C2-component mapping; the PN-projected GO:0034272 is NARROWER than the gene's existing generic GO:0032991, which is exactly the intended refinement (not an over-broad projection). As with the other C2 binders, part_of for an associating membrane-fission adaptor is defensible but borderline vs. an associated/recruitment relation — review flags this in suggested_questions. Ancestors correctly held too_broad.
Evidence alignment: PN cites Annual Review, a cardiovascular review, and PMID:19270696. Review uses primary PMID:17891140 (Bif-1/UVRAG autophagy), 21068542 (ATG9/Golgi fission), 11604418 (endophilin membrane tubulation), 15452144/16227588 (mitochondria/Bax, non-core), 12456676 (LPAAT, non-core). PMID:19270696 is not cited in this review; the PN reference list is shared-branch boilerplate, only loosely SH3GLB1-specific.
Verdict: Consistent; PN GO:0034272 refines the gene's generic GO:0032991 (more_specific) and the review captures it via MODIFY plus richer membrane-fission/tubulation MF/BP terms (all verified). No edits required.
