DNA-binding domain of T-box transcription factor 6, and related T-box proteins
TBX6 is a T-box transcription factor which plays an essential role in the fate determination of axial stem to become either neural or mesodermal. It also plays an essential role in the regulation of left/right patterning in mouse embryos, through effects on nodal cilia and perinodal signaling. This subfamily belongs to the T-box family of transcription factors which play a multitude of diverse functions throughout development. The founding member of the T-box family is Brachyury (also known as TBXT, or T). T-box family members share a conserved DNA-binding domain (T-box) which binds DNA in a sequence-specific manner. Common features shared by T-box family members are DNA-binding and transcriptional regulatory activity, a role in development, and conserved expression patterns.
Feature 1:DNA binding site [nucleic acid binding site]
Evidence:
Comment:based on related T-box transcription factors bound with DNA
Comment:T-box monomers dimerize upon DNA binding; some form weak dimers, others tight dimers, some may bind as non-associating monomers where the dimer is kept in register by the DNA
