Peptide aptamers: new tools to study protein interactions

J Steroid Biochem Mol Biol. 2001 Aug;78(2):105-11. doi: 10.1016/s0960-0760(01)00085-1.


The ability to specifically interfere with the function of proteins of pathological significance has been a goal for molecular medicine for many years. Peptide aptamers comprise a new class of molecules, with a peptide moiety of randomized sequence, which are selected for their ability to bind to a given target protein under intracellular conditions. They have the potential to inhibit the biochemical activities of a target protein, can delineate the interactions of the target protein in regulatory networks, and identify novel therapeutic targets. Peptide aptamers represent a new basis for drug design and protein therapy, with implications for basic and applied research, for a broad variety of different types of diseases.
