Abstract: | Syncytial muscles arise by the fusion of mononucleated myoblasts. Main cellular events during the fusion of mammalian and Drosophila myoblasts are the recognition and adhesion of myoblasts, F‐actin polymerization, formation of the fusion pore, blending of the cytoplasm and the integration of the fusing myoblast into the growing myotube. During the last twenty years many key players of myoblast fusion have been identified in the model organism Drosophila melanogaster. However, none of these proteins showed fusogenic characteristics. During the last five years, two new proteins have been identified in mice that control membrane remodeling and that possess fusogenic properties. These proteins might in the future help to increase our knowledge about the fundamental mechanism of myoblast fusion. |
