Predicted to enable DNA-binding transcription factor activity and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of DNA-templated transcription. Predicted to be located in nucleus. Is an ortholog of C. elegans tbx-35. In C. elegans, tbx-35 is involved in cell fate specification; chordate pharyngeal muscle development; and positive regulation of transcription by RNA polymerase II.
