LocalizationUniProt · AlphaFold · HPA

Whether an antibody against GABARAPL3 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody reachability: Intracellular
Secreted: No
Transmembrane segments: 0
Mean surface accessibility (rSASA): 0.29

Genetic constraint and essentialitygnomAD · DepMap

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

gnomAD missense Z: 0.82

Cancer expressionTCGA

Across TCGA tumor cohorts, this protein is over-expressed in roughly 4% of surveyed tumor types (aggregate summary; per-cohort expression, alteration, and survival load in the interactive view).

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads GABARAPL3 as an antibody target. Whether an autoantibody or antibody against GABARAPL3 could matter depends on whether native GABARAPL3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

GABARAPL3 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

The present source text does not explicitly label GABARAPL3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
