LocalizationUniProt · AlphaFold · HPA

Whether an antibody against IGHV3-9 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 IGHV3-9 as an antibody target. Whether an autoantibody or antibody against IGHV3-9 could matter depends on whether native IGHV3-9 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

IGHV3-9 is annotated at the cell surface, where native IGHV3-9 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 IGHV3-9 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
