Abstract
The crystal structure of human NF‐κB p52 in its specific complex with the natural κB DNA binding site MHC H‐2 has been solved at 2.1 Å resolution. Whereas the overall structure resembles that of the NF‐κB p50‐DNA complex, pronounced differences are observed within the ‘insert region’. This sequence segment differs in length between different Rel proteins. Compared with NF‐κB p50, the compact α‐helical insert region element is rotated away from the core of the N‐terminal domain, opening up a mainly polar cleft. The insert region presents potential interaction surfaces to other proteins. The high resolution of the structure reveals many water molecules which mediate interactions in the protein‐DNA interface. Additional complexity in Rel protein‐DNA interaction comes from an extended interfacial water cavity that connects residues at the edge of the dimer interface to the central DNA bases. The observed water network might acount for differences in binding specificity between NF‐κB p52 and NF‐κB p50 homodimers.
