<scene name='86/868180/Tbx21/3'>TBX21</scene> (for t-box transcription factor 21) or T-bet is a [https://en.wikipedia.org/wiki/Transcription_factor transcription factor], more precisely a [[T-box proteins]]. These transcription factors are known to be specialised in the regulation of developmental processes, especially with immune cells. The DNA binding domain of T-bet has a dimer structure composed of two identical chains (<scene name='86/868180/Chain_a/2'>A</scene> / <scene name='86/868180/Chain_b/2'>B</scene> ) with a total molecular weight of 76,37 kDA. This binding domain allows the protein to bind itself on the DNA promotor or regulator area. T-box protein is able to <scene name='86/868180/Tbx21_on_dna/1'>link two DNA molecules with only one dimer</scene>. Moreover, it is able to link two areas of the same DNA molecules which are far from each other and thus create a chromatin loop.
