Gene Description

UVRAG is a regulatory/adaptor subunit of the UVRAG-containing class III PI3K complex II (PI3KC3-C2) and a late autophagy/endolysosomal trafficking factor. It binds Beclin 1/PIK3C3 complex machinery, supports PI3P-dependent autophagosome maturation, and coordinates HOPS/class C VPS and SNARE-dependent fusion events at autophagosomes and endosomes. UVRAG also has supported but non-core roles in Golgi-ER retrograde trafficking, degradative endocytic traffic, cytokinesis, and autophagy-independent DNA repair/centrosome stability.

GO:0000323 lytic vacuole
IBA
GO_REF:0000033
MODIFY
Summary: Lytic vacuole is a non-human/generalized ancestor for UVRAG lysosome/endolysosomal localization.
Reason: For human UVRAG, lysosome, late endosome, and autophagosome/autophagosome membrane are more precise locations for the late autophagy and endosomal trafficking role.

Summary: Centromeric/chromosome localization is experimentally tied to UVRAG genome-stability biology but is not PN core.
Reason: UVRAG has an autophagy-independent DNA repair and chromosome/centrosome stability branch. Retain as non-core relative to class III PI3K/autophagosome maturation biology.

Summary: Autophagosome localization is directly relevant to UVRAG/PACER-mediated autophagosome maturation.
Reason: UVRAG is recruited to autophagosome-associated structures and participates in PI3KC3/HOPS activation during autophagosome maturation.

GO:0005783 endoplasmic reticulum
IEA
GO_REF:0000044
KEEP AS NON CORE
Summary: Endoplasmic reticulum localization is supported for the RINT1/NRZ retrograde trafficking branch.
Reason: UVRAG has a PtdIns(3)P-dependent ER tethering and Golgi-ER retrograde transport role. This is supported but secondary to the PN class III PI3K/autophagosome maturation focus.

GO:0006914 autophagy
IEA
GO_REF:0000117
MODIFY
Summary: Broad autophagy is directionally correct but should be narrowed to UVRAG autophagosome maturation/positive autophagy regulation.
Reason: UVRAG regulates class III PI3K/HOPS-dependent autophagosome maturation and Beclin1-PI3KC3 autophagy signaling; the parent autophagy term loses that specificity.

IEA
GO_REF:0000117
MODIFY
Summary: Vesicle-mediated transport is too broad for UVRAG; the supported processes are Golgi-ER retrograde transport and endolysosomal/autophagic trafficking.
Reason: UVRAG couples PtdIns(3)P-dependent ER tethering, ATG9 transport, endosome fusion, and autophagosome maturation. More specific transport terms should be used instead of the broad parent.

Summary: UVRAG is involved in PI3P biosynthesis as a PI3KC3-C2 regulatory subunit rather than as the lipid kinase itself.
Reason: UVRAG activates/regulates PIK3C3/VPS34 within PI3KC3-C2, which mediates formation of phosphatidylinositol 3-phosphate during autophagy/endosomal trafficking.

GO_REF:0000117

Summary: Protein-containing complex organization is too broad for UVRAG; SNARE/HOPS and PI3KC3-C2 complex roles are more specific.
Reason: UVRAG participates in specific PI3KC3-C2, HOPS/class C VPS, and SNARE assembly contexts. Generic complex organization should be replaced by the specific supported complex/process annotations.

Summary: The interaction evidence may be real, but generic protein binding is not an informative UVRAG function.
Reason: UVRAG has specific complex/adaptor roles in PI3KC3-C2, HOPS/class C VPS, SNARE, DNA-PK, and other assemblies. Retaining protein binding obscures the biological function and should be replaced by specific complex membership or binding terms where curatable.

Summary: UVRAG is involved in PI3P biosynthesis as a PI3KC3-C2 regulatory subunit rather than as the lipid kinase itself.

Summary: Cytoplasm is a broad legacy localization for UVRAG.

KEEP AS NON CORE
Summary: DNA repair is supported for UVRAG but is an autophagy-independent non-core branch in this PN review.
Reason: The strongest evidence supports UVRAG activation of DNA-PK in NHEJ and chromosomal stability, but this should not be treated as the proteostasis/autophagy core function.

Summary: UVRAG has a supported adaptor/regulatory subunit role in PI3KC3-C2 and late fusion machinery.
Reason: Add this as a more informative molecular-function annotation than generic protein binding. UVRAG links BECN1/PIK3C3 complex machinery with class C VPS/HOPS and SNARE-dependent trafficking during autophagosome/endosome maturation.

Core Functions

UVRAG acts as the UVRAG-defining regulatory/adaptor subunit of PI3KC3-C2, linking PIK3C3/PIK3R4/BECN1 complex activity to PI3P-dependent endosomal and late autophagy trafficking.

Suggested Questions for Experts

Q: Should UVRAG be curated directly to GO:0034272 phosphatidylinositol 3-kinase complex, class III, type II rather than the parent class III PI3K complex term?

Suggested experts: GO autophagy editors, ComplexPortal curators, Reactome autophagy curators

Q: Should UVRAG SNARE/HOPS activity be represented only by SNARE binding and SNARE complex assembly, or is a more specific autophagosome-lysosome fusion adaptor term needed?

Suggested experts: GO molecular function editors, autophagosome maturation experts

Q: Should UVRAG DNA repair and centrosome annotations remain non-core in autophagy-focused reviews even though they are experimentally supported?

Suggested experts: GO DNA repair editors, GO autophagy editors

Suggested Experiments

Experiment: Use UVRAG separation-of-function mutants that disrupt BECN1/PIK3C3 binding, HOPS/class C VPS binding, or SNARE binding, followed by PI3P imaging, STX17/HOPS recruitment, and autophagosome-lysosome fusion assays.

Hypothesis: PI3KC3-C2 complex engagement and HOPS/SNARE engagement define separable UVRAG contributions to PI3P production and autophagosome maturation.

Type: UVRAG autophagy maturation separation-of-function rescue

Experiment: Compare UVRAG wild type, DNA-PK-binding mutants, and CEP63/centrosome-interaction mutants in the same knockout-rescue background with autophagic flux, NHEJ reporter, and centrosome/chromosome segregation readouts.

Hypothesis: UVRAG autophagosome maturation and DNA repair/centrosome functions are genetically separable branches rather than one shared autophagy-dependent phenotype.

Type: parallel autophagy and genome-stability rescue assay
