Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in epidermis development. Acts upstream of or within embryonic neurocranium morphogenesis; epithelium development; and hard palate morphogenesis. Predicted to be active in nucleus. Is expressed in several structures, including blastoderm; digestive system; ethmoid cartilage; oral region; and sensory system. Human ortholog(s) of this gene implicated in several diseases, including Van der Woude syndrome; cleft lip; cleft palate; orofacial cleft 6; and popliteal pterygium syndrome. Orthologous to human IRF6 (interferon regulatory factor 6).
