    The 2.3-A crystal structure of the transcription factor NK-kappa B p50 homodimer bound to a palindromic kappa B site reveals that the Rel homology region folds into two distinct domains, similar to those in the immunoglobulin superfamily. The p50 dimer envelopes an undistorted B-DNA helix, making specific contacts along the 10-base-pair kappa B recognition site mainly through loops connecting secondary structure elements in both domains. The carboxy-terminal domains form a dimerization interface between beta-sheets using residues that are strongly conserved in the Rel family.
