The present invention provides compositions and methods relating to or derived from antigen binding proteins activate FGF21-mediated signaling. In embodiments, the antigen binding proteins specifically bind to (i) β-Klotho; (ii) FGFR1c, FGFR2c, FGFR3c or FGFR4; or (iii) a complex comprising β-Klotho
The present invention provides compositions and methods relating to or derived from antigen binding proteins activate FGF21-mediated signaling. In embodiments, the antigen binding proteins specifically bind to (i) β-Klotho; (ii) FGFR1c, FGFR2c, FGFR3c or FGFR4; or (iii) a complex comprising β-Klotho and one of FGFR1c, FGFR2c, FGFR3c, and FGFR4. In some embodiments the antigen binding proteins induce FGF21-like signaling. In some embodiments, an antigen binding protein is a fully human, humanized, or chimeric antibodies, binding fragments and derivatives of such antibodies, and polypeptides that specifically bind to (i) β-Klotho; (ii) FGFR1c, FGFR2c, FGFR3c or FGFR4; or (iii) a complex comprising β-Klotho and one of FGFR1c, FGFR2c, FGFR3c, and FGFR4. Other embodiments provide nucleic acids encoding such antigen binding proteins, and fragments and derivatives thereof, and polypeptides, cells comprising such polynucleotides, methods of making such antigen binding proteins, and fragments and derivatives thereof, and polypeptides, and methods of using such antigen binding proteins, fragments and derivatives thereof, and polypeptides, including methods of treating or diagnosing subjects suffering from type 2 diabetes, obesity, NASH, metabolic syndrome and related disorders or conditions.

1. A method of treating a condition in a subject in need thereof comprising administering a therapeutically effective amount of an antigen binding protein that induces FGF21-mediated signaling and comprises a heavy chain variable region comprising complementarity determining regions (CDRs) comprisin
1. A method of treating a condition in a subject in need thereof comprising administering a therapeutically effective amount of an antigen binding protein that induces FGF21-mediated signaling and comprises a heavy chain variable region comprising complementarity determining regions (CDRs) comprising the amino acid sequences of SEQ ID NO: 122, SEQ ID NO: 133, and SEQ ID NO: 148 and a light chain variable region comprising CDRs comprising the amino acid sequences of SEQ ID NO: 166, SEQ ID NO: 176, SEQ ID NO: 188 to the subject, wherein the condition is associated with decreased FGF21-like signaling activity. 2. The method of claim 1, wherein the antigen binding protein comprises a heavy chain variable domain comprising the amino acid sequence of SEQ ID NO: 68 and a light chain variable domain comprising an amino acid sequence of SEQ ID NO: 50. 3. The method of claim 1, wherein the antigen binding protein comprises a heavy chain comprising the amino acid sequence of SEQ ID NO: 32 and a light chain comprising an amino acid sequence of SEQ ID NO: 14. 4. The method of claim 1, wherein the antigen binding protein is a human antibody, a humanized antibody, chimeric antibody, a monoclonal antibody, a polyclonal antibody, a recombinant antibody, an antigen-binding antibody fragment, a single chain antibody, a diabody, a triabody, a tetrabody, a Fab fragment, an F(fab′)2 fragment, a domain antibody, an IgD antibody, an IgE antibody, an IgM antibody, an IgG1 antibody, an IgG2 antibody, an IgG3 antibody, an IgG4 antibody, or an IgG4 antibody having at least one mutation in the hinge region. 5. The method of claim 1, wherein the condition is treatable by lowering blood glucose, insulin or serum lipid levels. 6. The method of claim 1, wherein the condition is diabetes, obesity, dyslipidemia, NASH, cardiovascular disease or metabolic syndrome. 7. The method of claim 5, wherein the condition is type 2 diabetes.
