== Function ==
[https://www.uniprot.org/uniprot/TBXT_XENLA TBXT_XENLA] Involved in the transcriptional regulation of genes required for mesoderm formation and differentiation (PubMed:11869292). Binds to the palindromic T site 5'-TTCACACCTAGGTGTGAA-3' DNA sequence (PubMed:11111039). Causes dorsal mesodermal differentiation of animal cap ectoderm when co-expressed with wnt8 and noggin (PubMed:7906224). None of these molecules causes dorsal mesoderm formation when expressed alone (PubMed:7906224). Establishes the left/right axis at early gastrula stage by directly up-regulating mesodermal expression of zic3 (PubMed:11869292).<ref>PMID:11111039</ref> <ref>PMID:11869292</ref> <ref>PMID:7906224</ref>
