Description

Predicted to have RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and RNA polymerase II transcription factor binding activity. Involved in several processes, including animal organ development; face morphogenesis; and prechordal plate formation. Predicted to localize to nucleus. Used to study Axenfeld-Rieger syndrome. Human ortholog(s) of this gene implicated in Arts syndrome; Axenfeld-Rieger syndrome; Axenfeld-Rieger syndrome type 1; anterior segment dysgenesis 4; and ring dermoid of cornea. Is expressed in several structures, including brain; dental epithelium; digestive system; head; and mesoderm. Orthologous to human PITX2 (paired like homeodomain 2).
