LocalizationUniProt · AlphaFold · HPA

Whether an antibody against IGHV1-24 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 IGHV1-24 as an antibody target. Whether an autoantibody or antibody against IGHV1-24 could matter depends on whether native IGHV1-24 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

IGHV1-24 is annotated at the cell surface, where native IGHV1-24 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 IGHV1-24 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.

Seroatlas is the reference for exploring autoantibody and antibody serology at the human-protein level: the autoreactome and human serome, multiplex serology (HuProt, HuScan, VirScan, PhIP-Seq).
