Dystrophin is a protein that is located in muscles that work with movement. The job of Dystrophin is to produce muscle proteins that protects the skeletal, cardiovascular and nervous system. Dystrophin plays an important role in protein complex that work together to strengthen muscle fiber and help prevent injuries. It also plays a role in cell signaling between proteins and chemical signals. However its main job is connecting and weighing down each structural framework between proteins and molecules outside the cell. Duchenne Muscular Dystrophy (DMD) is a recessive muscle disorder caused by the mutation in the dystrophin gene. The word Dystrophy comes from Greek Dys- meaning abnormal and -atrophy meaning growth or nutrition.
