-  "TRANSFAC® class description C0044: The T domain has originally been discovered in Brachyury (T) the founder member of the T-box family. It encodes a DNA binding domain of about 180 amino acids. X-ray analysis of the T domain showed that it binds as a dimer to a 20 nucleotide partially palindromic sequence. A new type of specific DNA contact is seen, in which a carboxy-terminal helix is deeply embedded into an enlarged minor groove without bending the DNA."
