Dystrophin is an essential component of skeletal muscle cells. Its N-terminal domain binds to F-actin and its C terminus binds to the dystrophin-associated glycoprotein (DAG) complex in the membrane. CONCLUSIONS: The dystrophin ABD structure reveals a previously uncharacterised arrangement of the CH domains within the ABD. This observation has implications for the mechanism of actin binding by dystrophin and related proteins. Examining the position of three pathogenic missense mutations within the structure suggests that they exert their effects through misfolding of the ABD, rather than through disruption of the binding to F-actin^[1]
