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 myeloid dendritic cell differentiation; negative regulation of transcription by RNA polymerase II; and response to virus. Predicted to be located in cytosol; nucleolus; and nucleoplasm. Predicted to be active in nucleus. Orthologous to human BATF3 (basic leucine zipper ATF-like transcription factor 3).
