Controlling the activity of a protein is necessary for defining its function in vivo. RNA aptamers are capable of inhibiting proteins with high affinity and specificity, but this effect is not readily reversible. We describe a general method for discovering aptamers that bind and inhibit their target protein, but addition of a specific small molecule disrupts the protein-RNA complex. A SELEX protocol was used to raise RNA aptamers to the DNA repair enzyme, formamidopyrimidine glycosylase (Fpg… CONTINUE READING
