Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific; DNA-binding transcription repressor activity, RNA polymerase II-specific; and cAMP response element binding activity. Predicted to be involved in negative regulation of transcription by RNA polymerase II and regulation of cell cycle process. Predicted to act upstream of or within DNA replication; positive regulation of transcription by RNA polymerase II; and regulation of mitotic cell cycle, embryonic. Predicted to be located in nucleoplasm and spindle. Orthologous to human E4F1 (E4F transcription factor 1). [provided by Alliance of Genome Resources, Apr 2022]
