Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and identical protein binding activity. Predicted to be involved in several processes, including hepatocyte differentiation; negative regulation of cell cycle process; and regulation of cellular macromolecule biosynthetic process. Predicted to act upstream of or within regulation of transcription, DNA-templated. Predicted to be located in nuclear speck. Predicted to be part of RNA polymerase II transcription regulator complex. Orthologous to human E2F7 (E2F transcription factor 7). [provided by Alliance of Genome Resources, Apr 2022]
