Specific dsDNA recognition by a mimic of the DNA binding domain of the c-Myc/Max transcription factor†
Abstract
We here report on the synthesis of the first mimic of the DNA binding domain of the c-Myc/Max-bHLH-ZIP transcription factor able to selectively recognize its cognate E-box sequence 5′-CACGTG-3′ through the major groove of the double-stranded DNA. The designed peptidosteroid conjugate was shown to be effective as DNA binder in the presence of excess competitor DNA.
