Also found in: Medical.


A large protein that stabilizes muscle fibers by forming a link between the internal cytoskeleton and a protein complex in the plasma membrane that is connected to the extracellular matrix. Genetic mutations resulting in the absence of dystrophin cause Duchenne muscular dystrophy, and those resulting in insufficient or abnormal dystrophin cause Becker muscular dystrophy.
