Whether an antibody against PNAS-138 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 and autoantibody relevanceSeroatlas analysis

Seroatlas reads PNAS-138 as an antibody target. Whether an autoantibody or antibody against PNAS-138 could matter depends on whether native PNAS-138 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

PNAS-138 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 PNAS-138 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
