Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads PATE1 as an antibody target. Whether an autoantibody or antibody against PATE1 could matter depends on whether native PATE1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
PATE1 is annotated as secreted, so native PATE1 circulates and is directly accessible to antibodies. Secreted and cell-surface proteins are the autoantibody targets most likely to act like drugs, blocking or depleting the native protein.
Annotation status
The present source text does not explicitly label PATE1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
