OverviewNCBI Gene
The protein encoded by this gene is a member of the STAT family of transcription factors. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein plays a central role in exerting IL4 mediated biological responses. It is found to induce the expression of BCL2L1/BCL-X(L), which is responsible for the anti-apoptotic activity of IL4. Knockout studies in mice suggested the roles of this gene in differentiation of T helper 2 (Th2) cells, expression of cell surface markers, and class switch of immunoglobulins. Alternative splicing results in multiple transcript variants.[provided by RefSeq, May 2010]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads STAT6 as an antibody target. Whether an autoantibody or antibody against STAT6 could matter depends on whether native STAT6 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
STAT6 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 STAT6 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
