OverviewNCBI Gene

This gene encodes an uncharacterized protein with a C-terminal coiled-coil region. The gene is located on chromosome 20p13 in a 1.8 Mb region linked to a spinocerebellar ataxia phenotype, but this gene does not appear to be a disease candidate. [provided by RefSeq, Dec 2011]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against DNAAF9 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 DNAAF9 as an antibody target. Whether an autoantibody or antibody against DNAAF9 could matter depends on whether native DNAAF9 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

DNAAF9 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 DNAAF9 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
