A PNA-peptide chimera designed to mimic the biochemical function of transcription activators has been synthesized and characterized. The bis-PNA segment binds specifically to a DNA site while the 20-residue peptide is capable of binding to the transcription factors Gal11 and Gal80. The PNA-peptide chimera thus mimics one of the central functions of a native transcription activator, recruitment of transcription factors to a specific DNA site.
