Dystrophin Protein Role in Muscular Function

Dystrophin is a vital protein that plays a key role in stabilizing muscle fibers by linking the sarcomeres to the cell membrane, specifically the plasma membrane. It forms a protective link between the contractile elements inside the muscle cell and the external extracellular matrix, preventing muscle damage during contraction. As muscles contract and stretch, the mechanical stress exerted on the sarcomeres is transmitted across the membrane via dystrophin, which acts as a bridge, dispersing thi
