OverviewNCBI Gene
Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II and regulation of cell population proliferation. Predicted to act upstream of or within inferior colliculus development; negative regulation of neuron apoptotic process; and positive regulation of DNA-templated transcription. Predicted to be located in chromatin. Predicted to be part of transcription regulator complex. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Jul 2025]

Whether an antibody against TFAP2D 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 TFAP2D as an antibody target. Whether an autoantibody or antibody against TFAP2D could matter depends on whether native TFAP2D is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
TFAP2D 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 TFAP2D as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
