Ultrastructural basis for gene expression at the synapse: synapse-associated polyribosome complexes

J Neurocytol. 1996 Dec;25(12):717-34. doi: 10.1007/BF02284837.

Abstract

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