1. A polypeptide comprising an extracellular domain of an ActRIIA polypeptide, a linker domain having the sequence TGGG (SEQ ID NO:21), and an immunoglobulin Fc domain, wherein the extracellular domain comprises an amino acid sequence that is at least 97% identical to SEQ ID NO: 1, and wherein the immunoglobulin Fc domain is fused to the extracellular domain of the ActRIIA polypeptide by the linker domain, and wherein the polypeptide comprises an amino acid mutation at position 164 with respect to the sequence of SEQ ID NO:1. |
