Abstract
The present invention provides adapter-directed display systems for expressing exogenous polypeptide within a host cell and/or displaying the exogenous polypeptide on the outer surface of a genetic package. This subject systems are particularly useful for displaying a genetically diverse repertoire of monomeric and multimeric polypeptides. The invention also provides both expression and helper vectors and kits containing components of the subject display systems. Also provided are genetic packages displaying the exogenous polypeptides of particular interest. Further provided by the invention are methods of using the subject display systems.
