Enables DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including negative regulation of stem cell proliferation; negative regulation of transcription by RNA polymerase II; and regulation of meiotic cell cycle. Located in nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; sensory organ; and skin. Orthologous to human OVOL1 (ovo like transcriptional repressor 1). [provided by Alliance of Genome Resources, Apr 2022]
