The Ligand binding domain for each piece of the dimer has a very similar structure of an <scene name='RA_Mediated_T-reg_Differentiaition/Alpha-helical_domains/2'>Tα-helical sandwich</scene>. These alpha helices form a total of 12 domains per protein (referred to as H1-12), with an additional 2 beta sheets as well. Both monomers contain two regions of activity, the <scene name='RA_Mediated_T-reg_Differentiaition/Dimerization_interface/2'>dimerization interface</scene> and the ligand binding domain.
