OverviewNCBI Gene
This gene encodes a member of the doublecortin family. The protein encoded by this gene contains two doublecortin domains. The doublecortin domain has been demonstrated to bind tubulin and enhance microtubule polymerization. [provided by RefSeq, Sep 2010]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads DCDC2B as an antibody target. Whether an autoantibody or antibody against DCDC2B could matter depends on whether native DCDC2B is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
DCDC2B 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 DCDC2B as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
