Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in neuron differentiation and regulation of transcription by RNA polymerase II. Predicted to act 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. Orthologous to human OLIG3 (oligodendrocyte transcription factor 3). [provided by Alliance of Genome Resources, Apr 2022]
