OverviewNCBI Gene

YY1 is a ubiquitously distributed transcription factor belonging to the GLI-Kruppel class of zinc finger proteins. The protein is involved in repressing and activating a diverse number of promoters. YY1 may direct histone deacetylases and histone acetyltransferases to a promoter in order to activate or repress the promoter, thus implicating histone modification in the function of YY1.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against YY1 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 YY1 as an antibody target. Whether an autoantibody or antibody against YY1 could matter depends on whether native YY1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

YY1 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 YY1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
