OverviewNCBI Gene
This gene encodes a matrix protein which binds nuclear matrix and scaffold-associating DNAs through a unique nuclear architecture. The protein recruits chromatin-remodeling factors in order to regulate chromatin structure and gene expression. [provided by RefSeq, Apr 2016]

Protein binding partners of SATB1 in the human serome: UniProt-annotated complex subunits plus reported interactors. Each links to its own Seroatlas record.
Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads SATB1 as an antibody target. Whether an autoantibody or antibody against SATB1 could matter depends on whether native SATB1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SATB1 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 SATB1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
