RSK2 Mediates Muscle Cell Differentiation through Regulation of NFAT3
10 Jan 2007
Abstract excerpt
RSK2, an ERK downstream kinase, is a novel mediator of skeletal muscle cell differentiation through its regulation of NFAT3 activity. We found that the N-terminal (amino acids (aa) 1-68) and C-terminal (aa 416-674) kinase domains of RSK2 directly interacted with nuclear localization signal 1, the Ser/Pro repeat, and the polyproline domains (aa 261-365) of NFAT3. Upon A23187 stimulation, RSK2 induced nuclear...
