Antibody-like proteins for therapeutic and diagnostic use
Disclosed herein are recombinant protein scaffolds for use in producing antigen-binding proteins. Related antigen-binding proteins are also provided herein. In addition, nucleic acids encoding such recombinant protein scaffolds and antigen-binding proteins are also described. Vectors and cells useful for expression of the described proteins are also provided, as are methods of use.
1. A recombinant antigen-binding protein comprising the amino acid sequence of SEQ ID NO:1, 2, 3, 4, 5, 6, or 7.
2. A recombinant antigen-binding protein comprising the protein scaffold of SEQ ID NO:14, 16, 17, 18, 19, or 20.
3. The recombinant antigen-binding protein of claim 2 , further comprising an antigen-specific peptide of SEQ ID NO:15, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, or 44.
4. The recombinant antigen-binding protein of claim 2 , further comprising an epitope tag, a fluorophore, a radio isotope, or an enzyme.
