Abstract: The cloning of genes based on protein function has become a powerful tool for protein discovery and should play an important role in proteomics in general. We have recently reported a technique for the functional identification of protein targets by combining traditional affinity chromatography with cDNA phage display. This procedure, referred to as display cloning, directly couples biologically active natural products to the gene of their protein cellular target. We now report the cloning of a human gene, the α domain of F1 ATP synthase, using a synthetic scaffold molecule which serves as a prototype for a diverse chemical library. The ability to select genes from cDNA libraries using probes from combinatorial libraries would greatly increase the number of small molecule/protein interactions that can be identified. This method might prove valuable in furthering our understanding of biology and its application toward drug development.
