• PubMed Abstract: 
  

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. Dystrophin is therefore thought to serve as a link from the actin-based cytoskeleton of the muscle cell through the plasma membrane to the extracellular matrix. Pathogenic mutations in dystrophin result in Duchenne or Becker muscular dystrophy.
