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 several processes, including embryonic organ development; motile cilium assembly; and regulation of cilium assembly. Predicted to be active in nucleus. Is expressed in several structures, including embryo mesoderm; mesendoderm; primitive streak; and tail. Orthologous to human NOTO (notochord homeobox).
