OverviewNCBI Gene
This gene encodes a member of the tyrosine phosphatase family of proteins and exhibits dual specificity by dephosphorylating tyrosine as well as serine and threonine residues. This gene has been described as both a tumor suppressor and an oncogene depending on the cellular context. This protein may regulate neuronal proliferation and has been implicated in the progression of glioblastoma through its ability to dephosphorylate the p53 tumor suppressor. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2015]

Whether an antibody against DUSP26 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 DUSP26 as an antibody target. Whether an autoantibody or antibody against DUSP26 could matter depends on whether native DUSP26 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
DUSP26 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 DUSP26 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
