The conversion of the TCEd to a 'perfect' NF-kB binding site leads to a tighter binding of NF-kB to TCEd DNA and, as a functional consequence, to the activity of the 'converted' TCEd motifs in HeLa cells .
 cell line: HeLa cells; DNA: TCEd; protein: NF-kB; DNA: TCEd; protein: NF-kB; DNA: TCEd; DNA: TCEd DNA; DNA: 'perfect' NF-kB binding site; DNA: 'converted' TCEd motifs
