Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in cell fate specification and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within positive regulation of DNA-templated transcription. Predicted to be active in chromatin and nucleus. Is expressed in mandibular arch skeleton; maxilla; paraxial mesoderm; and stomodeum. Human ortholog(s) of this gene implicated in Abruzzo-Erickson syndrome; X-linked cleft palate with or without ankyloglossia; and cleft palate. Orthologous to human TBX22 (T-box transcription factor 22).
