OverviewNCBI Gene

This gene belongs to the forkhead family of transcription factors which are characterized by a distinct forkhead domain. Studies of the orthologous mouse protein indicate that it functions in kidney development by promoting nephron progenitor differentiation, and it also functions in the development of the retina and optic chiasm. It may also regulate inflammatory reactions and prevent autoimmunity. [provided by RefSeq, Apr 2014]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against FOXD1 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 FOXD1 as an antibody target. Whether an autoantibody or antibody against FOXD1 could matter depends on whether native FOXD1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

FOXD1 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 FOXD1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
