Dystrophin bound to cytoskeleton
WebBinds directly to dystrophin. Binding occurs at coiled-coil domains in C-terminal region of each protein. Complexes contain 2 syntrophin binding sites. N-terminal region of α-dystrobrevin associates with the … WebWhen dystrophin is missing the cystoskeleton will therefore be defective, and it has been supposed that this renders the muscle membrane more vulnerable to mechanical damage. With the discovery of animal strains lacking in dystrophin, this hypothesis has been put to experimental tests.
