Of all T-box genes only three, TBX2, TBX3 (p14 in hu- mans) is thought to fulfill an important protective role and Xenopus ET, are currently known to be transcriptional in preventing primary cells from oncogenic transforma- repressors, probably acting via a putative repression domain tion via its action in the p53 pathway.
