Abstract: A fibroblast growth factor 21 (FGF21) mutant protein and use thereof are provided. The FGF21 mutant protein is obtained through the following alteration based on an amino acid sequence of wild-type human FGF21: deleting a proline residue at position 171, or forming a disulfide bond before and after the proline residue at position 171 through substitution, deletion, or addition of one or more amino acid residues. A C-terminus of the FGF21 mutant protein of the present disclosure can resist the enzymatic degradation of fibroblast activation protein (FAP), and maintain an activity for binding to a ?-klotho receptor, which prolongs an in vivo half-life and efficacy of the FGF21 mutant protein.
