Summary: Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Contributes to DNA-binding transcription repressor activity, RNA polymerase II-specific. Involved in several processes, including DNA endoreduplication; negative regulation of G1/S transition of mitotic cell cycle; and negative regulation of cellular macromolecule biosynthetic process. Located in chromatin. Part of Myb complex and Rb-E2F complex. Is expressed in several structures, including embryonic/larval nervous system; endoderm anlage; extended germ band embryo; germ layer; and presumptive embryonic/larval system. Orthologous to human E2F4 (E2F transcription factor 4) and E2F5 (E2F transcription factor 5). [provided by Alliance of Genome Resources, Apr 2022]
