Caveat Receptor: Proteomes on Display

F.   J.   Stevens

Abstract

Display methods development is currently extending the application of this strategy beyond the generation of ligand binding reagents for research, clinical, or biotechnological purposes to its use as a primary research tool. Peptide- and cDNA display methods have the potential to contribute to understanding the mechanisms of certain classes of drugs and to help map protein-protein interactions of physiological importance. Although the critical contribution of comprehensive amino acid sequence databases has been recognized, of equal importance might be structural genomics concepts in the application of display system technology to proteomics research. Lessons learned from the study of antibody-antigen interactions are reviewed here and applied to the field of display technology with the goal of delineating major factors involved in the successful mimicry of natural protein-ligand interactions.
