Surface display systems allow enrichment of polypeptides with specific binding properties from libraries of sequence variants. A retroviral particle display system is described in which complex protein domains are inserted into the hypervariable region of a murine leukemia virus surface protein. Inserted domains are glycosylated, form multiple correct disulfide bonds, and are displayed on infectious virions. Enrichment of particles with specific binding properties due to inserted domains has been demonstrated, although recovery of bound virions requires further optimization. This system may extend display methodology to complex structures with binding properties that depend on post-translational modifications performed only by mammalian cells.
