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 anterior/posterior pattern specification; regulation of neurogenesis; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within regulation of DNA-templated transcription. Predicted to be active in nucleus. Is expressed in several structures, including central nervous system; neural rod; optic cup; spinal cord neural tube; and trigeminal placode. Orthologous to human HES6 (hes family bHLH transcription factor 6).
