Whether an antibody against PPY2P can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Cancer expressionTCGA
Across TCGA tumor cohorts, this protein is over-expressed in roughly 4% of surveyed tumor types (aggregate summary; per-cohort expression, alteration, and survival load in the interactive view).
Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads PPY2P as an antibody target. Whether an autoantibody or antibody against PPY2P could matter depends on whether native PPY2P is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
PPY2P 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 PPY2P as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
