ETS domain DNA and dimer complexes. (a) An Elk-1 ETS domain bound to its DNA recognition sequence. α-helices are in purple and β-strands in yellow. (b) An Elk-1 ETS domain dimer complex, showing the α1β1 loops providing the interface. The images were generated using VMD [63] and PovRay (http://www.povray.org/), using coordinates taken from the 1DUX crystal structure [18].
