  • Publication number: 20250179142
    Abstract: A fusion protein of GLP-1 and GDF15 and the use thereof. The fusion protein comprises a first polypeptide fragment, a second polypeptide fragment and a third polypeptide fragment which are sequentially connected from an amino terminal to a carboxyl terminal; and the three polypeptide fragments sequentially comprise a GLP-1 polypeptide, an immunoglobulin Fc region and a GDF15 active domain. The fusion protein provided has a GLP-1 and GDF15 dual-target activity. The fusion protein as a whole has excellent physicochemical properties and stability, and the two target molecules of GLP-1 and GDF15 have a good activity and pharmacokinetic balance, facilitating the exertion of a dual-target effect.
