- Description
- 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 camera-type eye development; left/right pattern formation; and nervous system development. Predicted to be located in cytoplasm. Predicted to be active in nucleus. Is expressed in several structures, including brain; dental epithelium; digestive system; head; and mesoderm. 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. Orthologous to human PITX2 (paired like homeodomain 2).
