  SH3GLB1 encodes endophilin B1/Bif-1, an N-BAR/SH3 membrane-curvature adaptor that links
  UVRAG/BECN1/PI3KC3-C2 autophagy signaling to ATG9-positive Golgi membrane fission and autophagosome
  assembly. Its core functions include PI3KC3 activation, adaptor-mediated association with
  UVRAG/Beclin 1, and membrane fission/tubulation at Golgi/autophagosome membranes. SH3GLB1 also has
  supported non-core roles in mitochondrial outer membrane dynamics, Bax/Bak-dependent apoptosis,
  receptor degradation, cytokinesis, and older lipid-binding/acyltransferase biochemistry.

    action: MODIFY
    reason: SH3GLB1/endophilin B1 contributes to membrane curvature, ATG9/Golgi fission, receptor degradation,
      and endocytic trafficking contexts; the broad endocytosis parent should be narrowed where possible.

    reason: The evidence supports positive regulation of autophagy/autophagosome assembly and a distinct 
      Bax/Bak mitochondrial apoptosis branch; direct autophagic cell death is a less precise and potentially

    activator/adaptor activity with PI3KC3-C2 context?
  experts:
  - GO autophagy editors
  - ComplexPortal curators

- question: Is membrane fission or positive regulation of membrane tubulation the best GO process for 
    Bif-1-mediated Atg9-positive Golgi membrane remodeling during autophagosome assembly?
  experts:
  - GO autophagy editors
  - membrane trafficking experts
- question: Should autophagic cell death annotations for Bif-1 be replaced by positive regulation of autophagy
    plus separate Bax/Bak mitochondrial apoptosis annotations?
  experts:
  - GO apoptosis editors
  - GO autophagy editors
suggested_experiments:
- description: Rescue SH3GLB1 knockout cells with N-BAR, SH3, and dimerization mutants and measure PI3KC3 
    activity, Atg9 redistribution, Golgi membrane fission, and LC3/WIPI autophagosome assembly.
  experiment_type: Bif-1 autophagy membrane-fission rescue assay
  hypothesis: Bif-1 requires both N-BAR membrane remodeling and SH3-dependent UVRAG/PI3KC3-C2 engagement to 
    support Atg9 trafficking and autophagosome assembly.
- description: Compare wild type and Bax-binding/mitochondrial-targeting SH3GLB1 mutants for mitochondrial 
    morphology, Bax/Bak activation, and autophagic flux in the same background.
  experiment_type: separation-of-function apoptosis versus autophagy assay
  hypothesis: SH3GLB1 mitochondrial apoptosis and PI3KC3-C2 autophagy roles are genetically separable.
