Agrin and the molecular choreography of synapse formation

Trends Neurosci. 1993 Feb;16(2):72-6. doi: 10.1016/0166-2236(93)90020-m.


High concentrations of neurotransmitter receptors characterize neuromuscular junctions as well as neuron-neuron synapses in the brain and periphery. Synaptic function is critically dependent upon this marshalling of neurotransmitter receptors to the post-synaptic membrane. This review discusses agrin's role in orchestrating the molecular topography of the post-synaptic apparatus at nerve-muscle synapses and the emerging evidence suggesting a role for agrin in synaptogenesis in the brain.
