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 several processes, including negative regulation of transcription by RNA polymerase II; post-anal tail morphogenesis; and somitogenesis. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in spondylocostal dysostosis. Orthologous to human HES7 (hes family bHLH transcription factor 7).
