This application relates generally to the production of polypeptides having specific antigen-binding properties of Fv domains, for example, insertable variable fragments of antibodies, and modified α1-α2 domains of NKG2D ligands. This application further relates to modified α1-α2 domains of NKG2D ligands attached to polypeptides, in some embodiments antibodies or fragments of antibodies. This application further relates to antigen-binding peptides derived from light and heavy chain antibody variable domains, which contain two linker regions and a split variable domain.
