Stretch-responsive small skeletal muscle X protein, Chisel The murine X-linked gene Chisel (Csl/Smpx) is selectively expressed in cardiac and skeletal muscle cells. It localizes to the costameric cytoskeleton of muscle cells through its association with focal adhesion proteins, where it may participate in regulating the dynamics of actin through the Rac1/p38 kinase pathway. Thus it is implicated in the maintenance of muscle integrity and in responses to biomechanical stress. |
