Whether an antibody against TRBV14 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 TRBV14 as an antibody target. Whether an autoantibody or antibody against TRBV14 could matter depends on whether native TRBV14 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
TRBV14 is annotated at the cell surface, where native TRBV14 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 TRBV14 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
