OverviewNCBI Gene
Enables DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including regulation of gene expression; regulation of signal transduction; and transcription by RNA polymerase II. Predicted to be located in cytoplasm and nucleus.

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