Researchers at the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) developed a mouse model that enables them to look inside a working muscle and identify the proteins that allow the sarcomere to contract, relax, communicate its energy needs, and adapt to exercise. Specifically, they were able to map proteins in defined subregions of the sarcomere, starting from the "Z-disc," the boundary between neighboring sarcomeres. This in and of itself was a significant step forward in the study of striated muscle.
