PubMed Abstract: Members of the rel/NFkappaB family of transcription factors play a vital role in the regulation of rapid cellular responses, such as those required to fight infection or react to cellular stress. Members of this family of proteins form homo- and heterodimers with differing affinities for dimerization. They share a structural motif known as the rel homology region (RHR), the C-terminal one third of which mediates protein dimerization. Crystal structures of the rel/NFkappaB family members p50 and p65 in their DNA-bound homodimeric form have been solved. These structures showed that the residues from the dimerization domains of both p50 and p65 participate in DNA binding and that the DNA-protein and protein dimerization surfaces form one continuous overlapping interface. We desired to investigate the contribution of DNA to NFkappaB dimerization and to identify the mechanism for the selective association of rel/NFkappaB family peptides into transcriptionally active dimers.
