OverviewNCBI Gene
The protein encoded by this gene is a post-proline cleaving aminopeptidase expressed in quiescent lymphocytes. The resting lymphocytes are maintained through suppression of apoptosis, a state which is disrupted by inhibition of this novel serine protease. The enzyme has strong sequence homology with prolylcarboxypeptidase and is active at both acidic and neutral pH. [provided by RefSeq, Jul 2008]

Whether an antibody against DPP7 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 DPP7 as an antibody target. Whether an autoantibody or antibody against DPP7 could matter depends on whether native DPP7 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
DPP7 is annotated as secreted, so native DPP7 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 DPP7 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
