These findings demonstrate that interaction of both subunits of the heterodimeric NF-kappa B complex with DNA is required for DNA binding and transcriptional activation and suggest that transcriptional activation mediated by the individual rel-related proteins will differ dramatically, depending on the specific kappa B motifs present.
 protein: heterodimeric NF-kappa B complex; DNA: specific kappa B motifs; protein: rel-related proteins; protein: NF-kappa B complex
