Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads USP17L23 as an antibody target. Whether an autoantibody or antibody against USP17L23 could matter depends on whether native USP17L23 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

USP17L23 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 USP17L23 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
