    • The present invention provides compositions and methods relating to or derived from antigen binding proteins and antigen binding protein-FGF21 fusions that specifically bind to β-Klotho, or β-Klotho and one or more of FGFR1c, FGFR2c, FGFR3c, and FGFR4. In some embodiments the antigen binding proteins and antigen binding protein-FGF21 fusions induce FGF21-like signaling. In some embodiments, an antigen binding protein or antigen binding protein-FGF21 fusion antigen binding component is a fully human, humanized, or chimeric antibody, binding fragments and derivatives of such antibodies, and polypeptides that specifically bind to β-Klotho, or β-Klotho and one or more of FGFR1c, FGFR2c, FGFR3c, and FGFR4. Other embodiments provide nucleic acids encoding such antigen binding proteins and antigen binding protein-FGF21 fusions, and fragments and derivatives thereof, and polypeptides, cells comprising such polynucleotides, methods of making such antigen binding proteins and antigen binding protein-FGF21 fusions, and fragments and derivatives thereof, and polypeptides, and methods of using such antigen binding proteins and antigen binding protein-FGF21 fusions, 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.
    • 本发明提供与抗原结合蛋白和特异性结合ß-Klotho或ß-Klotho以及FGFR1c,FGFR2c,FGFR3c和FGFR4中的一种或多种的抗原结合蛋白和抗原结合蛋白-FGF21融合物相关或衍生的组合物和方法。 在一些实施方案中,抗原结合蛋白和抗原结合蛋白FGF21融合物诱导FGF21样信号传导。 在一些实施方案中,抗原结合蛋白或抗原结合蛋白-FGF21融合抗原结合组分是完全人,人源化或嵌合抗体,这种抗体的结合片段和衍生物,以及特异性结合ß-Klotho或ß- Klotho和FGFR1c,FGFR2c,FGFR3c和FGFR4中的一种或多种。 其他实施方案提供编码这种抗原结合蛋白和抗原结合蛋白-FGF21融合体的核酸,及其片段和衍生物,以及多肽,包含这种多核苷酸的细胞,制备这种抗原结合蛋白的方法和抗原结合蛋白-FGF21融合物, 其衍生物和多肽,以及使用这种抗原结合蛋白和抗原结合蛋白-FGF21融合体,其片段和衍生物和多肽的方法,包括治疗或诊断患有2型糖尿病,肥胖症,NASH,代谢综合征和 相关疾病或病症。
