Predicted to enable several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and promoter-specific chromatin binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including cell volume homeostasis; cilium assembly; and regulation of transcription, DNA-templated. Predicted to be located in chromatin; cytoplasm; and nucleoplasm. Predicted to be part of RNA polymerase II transcription regulator complex. Orthologous to human E2F4 (E2F transcription factor 4).
