Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and methyl-CpG binding activity. Predicted to be involved in negative regulation of transcription, DNA-templated and regulation of transcription by RNA polymerase II. Predicted to be located in cytosol; nucleolus; and plasma membrane. Predicted to be active in nucleoplasm. Orthologous to human ZBTB33 (zinc finger and BTB domain containing 33).
