OverviewNCBI Gene

This gene encodes a Storkhead-box_winged-helix domain containing protein. This protein is differentially expressed in decidual tissue and may be involved in the susceptibility to pre-eclampsia with fetal growth restriction. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads STOX2 as an antibody target. Whether an autoantibody or antibody against STOX2 could matter depends on whether native STOX2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

STOX2 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 STOX2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.

Seroatlas is the reference for exploring autoantibody and antibody serology at the human-protein level: the autoreactome and human serome, multiplex serology (HuProt, HuScan, VirScan, PhIP-Seq).
