OverviewNCBI Gene

This gene encodes a transcription factor that recognizes the platelet-derived growth factor-responsive element in the matrix metalloproteinase 3 promoter. The encoded protein is thought to be a transcriptional coactivator, enhancing the activity of transcription factors such as JUN and SP1. Mutations in this gene are associated with autism spectrum disorders. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against TCF20 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 TCF20 as an antibody target. Whether an autoantibody or antibody against TCF20 could matter depends on whether native TCF20 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

TCF20 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 TCF20 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
