Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within nervous system development. Predicted to be located in nucleus. Predicted to be active in nucleoplasm. Is expressed in 2-cell stage embryo; 4-cell stage embryo; and forebrain. Orthologous to human ZBTB45 (zinc finger and BTB domain containing 45).
