OverviewNCBI Gene
Predicted to enable ephrin receptor binding activity. Predicted to be involved in ephrin receptor signaling pathway; neuron remodeling; and substrate-dependent cell migration. Predicted to act upstream of or within negative regulation of ubiquitin-dependent protein catabolic process and regulation of ephrin receptor signaling pathway. Located in cytosol and nucleoplasm.

Protein binding partners of ANKS1A in the human serome: UniProt-annotated complex subunits plus reported interactors. Each links to its own Seroatlas record.
Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads ANKS1A as an antibody target. Whether an autoantibody or antibody against ANKS1A could matter depends on whether native ANKS1A is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
ANKS1A 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 ANKS1A as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
