ULTRASTRUCTURAL BASIS FOR GENE-EXPRESSION AT THE SYNAPSE - SYNAPSE-ASSOCIATED POLYRIBOSOME COMPLEXES

This review summarizes what is known about the protein synthetic machi nery that is selectively localized beneath postsynaptic sites on the d endrites of CNS neurons. This machinery, made up of polyribosomes and associated membranous cisterns, allows a local synthesis of key protei ns at individual postsynaptic sites.
