Ligand-binding, dimerized polypeptide fusions

Ligand-binding, dimerized polypeptide fusions comprising two polypeptide chains are disclosed. Each of the polypeptide chains comprises a ligand-binding domain of either a growth factor receptor or a hormone receptor joined to an immunoglobulin constant region polypeptide. Dimerization of the polype...

Zusammenfassung:Ligand-binding, dimerized polypeptide fusions comprising two polypeptide chains are disclosed. Each of the polypeptide chains comprises a ligand-binding domain of either a growth factor receptor or a hormone receptor joined to an immunoglobulin constant region polypeptide. Dimerization of the polypeptide fusion results in enhancement of biological activity. The immunoglobulin constant region polypeptide may comprise an immunoglobulin heavy chain constant region domain and hinge region.
