- 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 circulatory system development; cloaca development; and regulation of cardiac muscle cell proliferation. Predicted to be active in chromatin and nucleus. Is expressed in several structures, including cardiovascular system; digestive system; integument; mesoderm; and nervous system. Human ortholog(s) of this gene implicated in atrial heart septal defect; atrial heart septal defect 4; congenital heart disease; tetralogy of Fallot; and ventricular septal defect. Orthologous to human TBX20 (T-box transcription factor 20).
