This invention provides a new in vitro screening method for the detection of protein-protein and other interactions. The method has been developed and applied to a commercial cDNA library to search for novel protein-protein interactions. PDZ, WW and SH3 domains from PSD95, Nedd4, Src, Abl and Crk proteins were used as test targets. 12 novel putative and 2 previously reported interactions were identified for 6 protein interaction modules in test screens. The novel screening format, dubbed TAIS (target-assisted iterative screening), provides an alternative platform to existing technologies for a pair-wise characterization of protein-protein, and other, interactions.
