Enables cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in several processes, including asymmetric neuroblast division; cartilage development; and positive regulation of cell differentiation. Predicted to act upstream of or within several processes, including neurogenesis; regulation of timing of neuron differentiation; and regulation of transcription, DNA-templated. Predicted to be part of transcription regulator complex. Predicted to be active in nucleus. Orthologous to human SOX5 (SRY-box transcription factor 5).
