An in vitro system for generating sequence, and thus structural, diversity in proteins is described. The system can be constructed using appropriately selected nucleic acid molecules that encode regions of a selected protein or proteins and recombination signal sequences (RSS). The selected protein(s) can be, for example, immunoglobulin (Ig) V, D, J and/or C regions, regions of a non-immunoglobulin (non-Ig) protein, or a combination of Ig regions and non-Ig regions. Assembly of such appropriately selected components and their introduction into suitable recombination-competent host cells allows for recombination between the RSS sequences and introduction of sequence and structural diversity into the protein(s). |
