Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within negative regulation of transcription by RNA polymerase II; spinal cord motor neuron cell fate specification; and spinal cord motor neuron migration. Predicted to be active in nucleus. Is expressed in several structures, including central nervous system; future hindbrain; genitourinary system; inner ear; and skeletal muscle. Orthologous to human OLIG3 (oligodendrocyte transcription factor 3). [provided by Alliance of Genome Resources, Apr 2022]
