    Summary
    Enables DNA-binding transcription factor activity, RNA polymerase II-specific and DNA-binding transcription factor binding activity. Involved in negative regulation of gene expression; nervous system development; and regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including anlage in statu nascendi; gut section; head epidermis primordium; neurosecretory neurons; and segmentally-repeated neuroblast. Used to study obesity.
