OverviewNCBI Gene

This gene encodes a member of the T cell factor/lymphoid enhancer factor family of transcription factors. These transcription factors are activated by beta catenin, mediate the Wnt signaling pathway and are antagonized by the transforming growth factor beta signaling pathway. The encoded protein contains a high mobility group-box DNA binding domain and participates in the regulation of cell cycle genes and cellular senescence. [provided by RefSeq, Nov 2010]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against TCF7L1 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 TCF7L1 as an antibody target. Whether an autoantibody or antibody against TCF7L1 could matter depends on whether native TCF7L1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

TCF7L1 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 TCF7L1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
