STRUCTURE OF THE NUCLEAR FACTOR KAPPA-B (NF-KB) P50 HOMODIMER
|
Overview
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.
