The extracellular matrix at the neuromuscular junction plays many roles. The matrix plays a structural role in that it maintains the spatial relationship between the muscle cell, Schwann cell, and presynaptic motor neuron. The matrix also plays a role in cell‐to‐cell signaling. The most studied member of this group is the heparan sulfate proteoglycan, agrin. Agrin is an integral member of the synaptic matrix, and it plays the pivotal role of instructing the muscle cell to aggregate acetylcholine receptors (AChRs) to the synapse. Agrin is released by the motor neuron, where it binds stably to the extracellular matrix. Agrin interacts with the muscle‐specific tyrosine kinase (MuSK). Mice that lack agrin, or MuSK, fail to form neuromuscular junctions. Thus, the extracellular matrix is critical to both the structure and function of the neuromuscular junction.
