Whether an antibody against DUS1L 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 DUS1L as an antibody target. Whether an autoantibody or antibody against DUS1L could matter depends on whether native DUS1L is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
DUS1L 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 DUS1L as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
