  • Patent number: 11117969
    Abstract: 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 ?1-?2 domains of NKG2D ligands. This application further relates to modified ?1-?2 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.

  • Publication number: 20150165065
    Abstract: This invention describes soluble, monovalent, non-natural protein molecules that can activate NK cells and certain T-cells to attack specific cellular target cells by attaching the NKG2D-binding portions of monovalent MICA or MICB protein, i.e. their ?1-?2 platform domain, to the intended target cell specifically. The ?1-?2 domain is contiguous with a heterologous ?3 domain that has been genetically modified to bind directly or indirectly to the extracellular aspect of the target cell, thereby serving as the targeting domain. The genetic modification to create a non-natural and non-terminal targeting motif within the ?3 domain can include a portion of an antibody, another protein molecule or portion thereof, a peptide, or a non-natural, modified ?3 domain of a MIC protein.
