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.

Protein binding partners of YY2 in the human serome: UniProt-annotated complex subunits plus reported interactors. Each links to its own Seroatlas record.
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.
