Whether an antibody against MTRNR2L3 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 MTRNR2L3 as an antibody target. Whether an autoantibody or antibody against MTRNR2L3 could matter depends on whether native MTRNR2L3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
MTRNR2L3 is annotated as secreted, so native MTRNR2L3 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 MTRNR2L3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
