Enables DNA-binding transcription factor activity, RNA polymerase II-specific. Involved in regulation of nuclear cell cycle DNA replication. Acts upstream of or within several processes, including negative regulation of cell population proliferation; respiratory gaseous exchange by respiratory system; and suckling behavior. Located in cytoplasm and nucleus. Part of transcription regulator complex. Is expressed in several structures, including central nervous system; embryo mesenchyme; genitourinary system; limb; and sensory organ. Orthologous to human DACH1 (dachshund family transcription factor 1). [provided by Alliance of Genome Resources, Apr 2022]
