<jats:title>Abstract</jats:title><jats:p>The proper function of skeletal muscles relies on their ability to process signals derived from motor neurons, transmit stimuli along the muscle fibers, contract, and regenerate efficiently after injury. The dystrophin–glycoprotein complex (DGC; also called the dystrophin‐associated protein complex) plays a central role in all of these processes. It acts as a transmembrane platform that anchors the extracellular matrix (ECM) to the intracellular cytoskeleton and makes muscle fibers more resistant to injury. The DGC also contributes to the transmission of contraction‐evoked force from the sarcomere to the ECM. The dysfunction of DGC‐associated proteins can lead to myopathies, including Duchenne's muscular dystrophy, manifested by progressive muscle damage and impairments in regeneration. The DGC also plays a pivotal role in the organization of neuromuscular junctions (NMJs), where it stabilizes postsynaptic machinery, including receptors for the neurotransmitter acetylcholine (AChRs). Here, we focus on the role of the DGC complex in NMJ and skeletal muscle physiology and discuss the novel components that are associated with the complex.</jats:p>
