Synthetic activators that mimic the ability of native transcription factors to recruit the RNA polymerase holoenzyme to specific promoters could, in principle, be constructed by joining a sequence-specific DNA binding moiety with a molecule able to bind the holoenzyme. We report here that a peptide nucleic acid (PNA)-peptide chimera is capable of activating transcription in vitro in a HeLa nuclear...
There is currently great interest in the fabrication of protein-detecting arrays comprised of large numbers of immobilized protein capture agents. While most efforts in this arena have focused on the use of biomolecules such as antibodies and nucleic acid aptamers as capture agents, synthetic species have many potential advantages. However, synthetic molecules isolated from combinatorial libraries...
