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 several processes, including regulation of gene expression; regulation of inflammatory response; and type 2 immune response. Predicted to be located in nucleus. Predicted to be active in nucleoplasm. Orthologous to human BCL6B (BCL6B transcription repressor). [provided by Alliance of Genome Resources, Apr 2022]
