Whether an antibody against TRBV7-4 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 TRBV7-4 as an antibody target. Whether an autoantibody or antibody against TRBV7-4 could matter depends on whether native TRBV7-4 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
TRBV7-4 is annotated at the cell surface, where native TRBV7-4 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 TRBV7-4 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
