    Summary
    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 negative regulation of transcription by RNA polymerase II; regionalization; and ring gland development. Located in nucleus. Is expressed in several structures, including anlage in statu nascendi; circulatory system primordium; epithelial furrow; head epidermis primordium; and head segment.
