ABSTRACT:
The present invention provides methods and compositions for interaction trap assays for detecting protein-protein, protein-DNA, or protein-RNA interactions. The methods and compositions of the invention may also be used to identify agents which may agonize or antagonize a protein-protein, protein-DNA, or protein-RNA interactions. In certain embodiments, the interaction trap system of the invention is useful for screening libraries with greater than 107members. In other embodiments, the interaction trap system of the invention is used in conjunction with flow cytometry. The invention further provides a means for simultaneously screening a target protein or nucleic acid sequence for the ability to interact with two or more test proteins or nucleic acids.
