OverviewNCBI Gene

The protein encoded by this gene is a transcription factor that includes several Kruppel-like zinc fingers in its C-terminal region. It possesses both activation and repression domains, and it can therefore have both positive and negative effects on the transcription of target genes. This gene has an intronless coding region, and it appears to have arisen by retrotransposition of the related YY1 transcription factor gene, which is located on chromosome 14.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against YY2 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 YY2 as an antibody target. Whether an autoantibody or antibody against YY2 could matter depends on whether native YY2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

YY2 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 YY2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
