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