OverviewNCBI Gene

Members of the protein-tyrosine phosphatase superfamily cooperate with protein kinases to regulate cell proliferation and differentiation. This gene encodes a dual specificity phosphatase that acts on both phosphotyrosine and phosphoserine/threonine residues. The encoded protein is expressed in testis. [provided by RefSeq, Mar 2023]

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads DUSP13A as an antibody target. Whether an autoantibody or antibody against DUSP13A could matter depends on whether native DUSP13A is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

DUSP13A 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 DUSP13A as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
