The beta barrels also serve as part of the cradle, fitting into the major groove of DNA over two turns.
The domain is the main site of dimer interface, with each <scene name='56/567269/Ku70_dimer/4'>β-barrel</scene> being composed of seven β strands with the majority in antiparallel arrangement. The quantity of the strands lends the structures to be symmetrical.  Both <scene name='56/567269/Ku70_dimer/4'>β-barrels</scene> in the dimer form the base of the cradle by fitting in the grooves of <scene name='56/567269/Bound_dna/3'>DNA</scene>.
