OverviewNCBI Gene

This gene encodes an RNA-binding protein that is active in regulating gene expression by modulating protein translation during embryonic development. Mouse studies identified the corresponding protein to be under strict control during cell differentiation and to be a maternally provided gene product. [provided by RefSeq, Apr 2009]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against BICC1 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 BICC1 as an antibody target. Whether an autoantibody or antibody against BICC1 could matter depends on whether native BICC1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

BICC1 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 BICC1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
