DNA sequence recognition by NF kappa B p50 homodimer: strict and obscure recognition sites in the binding sequence

Nucleosides Nucleotides Nucleic Acids. Apr-Jul 2001;20(4-7):669-72. doi: 10.1081/NCN-100002347.


5-Formyl- and 5-(formylmethyl)-2'-deoxyuridines are introduced into a kappa B site instead of thymidine(s) in order to understand target sequence specificity of NF kappa B. It was found that one thymidine in the kappa B site is particularly important for the sequence specific recognition by NF kappa B.
