OverviewNCBI Gene
This gene encodes a transmembrane protein that functions in copper transport across membranes. This protein is localized to the trans Golgi network, where it is predicted to supply copper to copper-dependent enzymes in the secretory pathway. It relocalizes to the plasma membrane under conditions of elevated extracellular copper, and functions in the efflux of copper from cells. Mutations in this gene are associated with Menkes disease, X-linked distal spinal muscular atrophy, and occipital horn syndrome. Alternatively-spliced transcript variants have been observed.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads ATP7A as an antibody target. Whether an autoantibody or antibody against ATP7A could matter depends on whether native ATP7A is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
ATP7A is annotated at the cell surface, where native ATP7A is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.
Annotation status
The present source text does not explicitly label ATP7A as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
