The present invention relates to biologically active fusion proteins containing the IgG2 hinge as a multimerization domain capable of multimerizing proteins, peptides and small molecules which are active or more active in multimeric form; compositions comprising such fusion proteins; and methods of making and using such fusion proteins. 1151-. (canceled)152. A fusion protein comprising an IgG2 hinge domain monomer and an immunoglobulin Fc domain monomer , wherein the immunoglobulin Fc domain monomer is selected for poor binding to Fc gamma receptors.153. The fusion protein of claim 152 , wherein the IgG2 hinge domain monomer is at least 95% homologous to SEQ ID NO: 1.154. The fusion protein of claim 152 , wherein the IgG2 hinge domain monomer is 100% homologous to SEQ ID NO: 1.155. The fusion protein of claim 152 , wherein the IgG2 hinge domain monomer comprises at least two C-X-X-C motifs.156. The fusion protein of claim 155 , wherein the XX in the C-X-X-C motif comprises V-E or P-P.157. The fusion protein of claim 152 , wherein the immunoglobulin Fc domain monomer is an IgG1 claim 152 , IgG2 claim 152 , IgG3 or IgG4 Fc domain monomer selected for poor binding to Fc gamma receptors.158. The fusion protein of claim 152 , wherein the immunoglobulin Fc domain monomer is an IgE Fc domain monomer.159. The fusion protein of or wherein said immunoglobulin Fc domain monomer is mutated to bind poorly to Fc gamma receptors.160. The fusion protein of claim 159 , wherein said Fc domain is mutated at one or more of positions 233 claim 159 , 234 claim 159 , 235 claim 159 , 236 claim 159 , 238 claim 159 , 239 claim 159 , 265 claim 159 , 269 claim 159 , 270 claim 159 , 292 claim 159 , 293 claim 159 , 295 claim 159 , 296 claim 159 , 297 claim 159 , 303 claim 159 , 327 claim 159 , 329 claim 159 , 338 claim 159 , 376 claim 159 , and/or 414.161. The fusion protein of or wherein said immunoglobulin Fc domain monomer is modified to bind poorly to Fc gamma receptors.162. The fusion ...
