Assembly and plasticity of the glutamatergic postsynaptic specialization

Curr Opin Neurobiol. 2003 Feb;13(1):111-8. doi: 10.1016/s0959-4388(03)00008-4.

Abstract

Glutamate mediates most excitatory synaptic transmission in the brain. Synaptic strength at glutamatergic synapses shows a remarkable degree of use-dependent plasticity and such modifications may represent a physiological correlate to learning and memory. Glutamate receptors and downstream enzymes are organized at synapses by cytoskeletal proteins containing multiple protein-interacting domains. Recent studies demonstrate that these 'scaffolding' proteins within the postsynaptic specialization have the capacity to promote synaptic maturation, influence synapse size, and modulate glutamate receptor function.
