LocalizationUniProt · AlphaFold · HPA

Whether an antibody against TRBJ1-4 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 TRBJ1-4 as an antibody target. Whether an autoantibody or antibody against TRBJ1-4 could matter depends on whether native TRBJ1-4 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

TRBJ1-4 is annotated at the cell surface, where native TRBJ1-4 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 TRBJ1-4 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.

Canonical record: https://seroatlas.com/gene/TRBJ1-4. Study-independent annotations aggregated from UniProt, Human Protein Atlas, PubMed, IEDB, Pfam, InterPro, Gene Ontology, AlphaFold, gnomAD, DepMap, ClinVar, TCGA. Catalog release seroatlas-reviewed-human-uniprot-20260313.

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).
