Abstract
Since the introduction of the yeast display platform, this method has increasingly gained popularity for the discovery and affinity maturation of antibodies and other protein scaffolds intended for antigen recognition. Yeast display is particularly well suited for the selection of antigen-binding Fc fragments (Fcabs) as it allows rapid combinatorial library construction via gap repair-driven homologous recombination and an efficient display of a glycosylated Fc able to interact with Fcγ receptors. Apart from expression-related normalization, isolation of properly folded Fcabs can be guided efficiently by simultaneous staining with ligands such as protein A, FcγRI, or the conformation-sensitive anti-FigCH2 antibody, whose binding is critically dependent on the integrity of the Fc structure. The particular properties of the Fcab scaffold, such as its homodimeric state which can promote binding to multiple antigen molecules, require modifications of traditional affinity maturation strategies. Preferred to equilibrium selections are kinetically driven antigen selections, designed to specifically influence the binding off-rate, which in many cases augments the desired biological effect. A simple design of a yeast-displayed heterodimeric Fc fragment is described and can be used as a general guideline for affinity selection of Fcabs with an asymmetric binding site. Overall, this chapter underlines the importance of the versatile yeast display technique for the optimization of the novel Fcab scaffold for antigen recognition.
