What is different about dystrophin in muscles with DMD versus healthy
muscles? *
Dystrophin breaks down the lining of the sarcolemma and therefore makes DMD
muscles weak
Dystrophin attaches to enzymes in muscles with DMD and begins the process of
breaking down proteins
An excess of dystrophin in DMD muscles creates chains of proteins that help myosin
attach to actin which contracts the muscle
Dystrophin protein chains are too short in DMD muscles and so does not connect
sarcolemma to the myofibril
