Abstract
Methods of generating fusion protein variants are provided that comprise introducing sequence diversity at the junction region or regions in the fusion and allows for the generation of variants having a desired activity. Examples include immunoglobulins comprising a domain or polypeptide inserted into, or replacing, a CDR. Also provided are polynucleotides encoding a fusion protein and comprising two or more RSSs, and compositions and host cells comprising same, as well as fusion proteins variants produced by the described methods.
