LocalizationUniProt · AlphaFold · HPA

Whether an antibody against CHCHD2P9 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 CHCHD2P9 as an antibody target. Whether an autoantibody or antibody against CHCHD2P9 could matter depends on whether native CHCHD2P9 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

CHCHD2P9 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

The present source text does not explicitly label CHCHD2P9 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).
