Summary: Enables DNA-binding transcription repressor activity; core promoter sequence-specific DNA binding activity; and enzyme binding activity. Involved in several processes, including muscle cell fate specification; olfactory behavior; and pharynx development. Located in cytoplasm and nucleus. Is expressed in several structures, including amphid neurons; anal region; head; pharynx; and vulva. Human ortholog(s) of this gene implicated in atrial heart septal defect; heart septal defect; ulnar-mammary syndrome; and vertebral anomalies and variable endocrine and T-cell dysfunction. Orthologous to human TBX2 (T-box transcription factor 2) and TBX3 (T-box transcription factor 3). [provided by Alliance of Genome Resources, Dec 2024]

TBX-2 and SUMO-conjugating enzymes are necessary for ABa-derived pharyngeal muscle, and we hypothesize that TBX-2 function requires sumoylation.

The analysis suggests that a positive feedback loop between tbx-2 and pha-4 is required for blastomere-derived precursors to commit to pharyngeal muscle fate.
