Enables DNA-binding transcription factor activity; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and chromatin binding activity. Acts upstream of or within several processes, including cell volume homeostasis; cilium assembly; and regulation of transcription, DNA-templated. Located in chromatin and nucleus. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Used to study otitis media. Orthologous to human E2F4 (E2F transcription factor 4). [provided by Alliance of Genome Resources, Apr 2022]
