Abstract:
Synaptically activated, rapid and dendritic synthesis of new proteins has long been proposed to mediate long-lasting changes at the synapse [Steward O, Schuman EM: Protein synthesis at synaptic sites on dendrites.Annu Rev Neurosci 2001, 24:299-325]. Studies of group 1 metabotropic glutamate receptor-dependent long-term depression (mGluR-LTD) have provided new insight into dendritic or local translation and plasticity. Here we highlight these exciting results and discuss how synaptic activity controls local translation, the proteins that are synthesized in dendrites, how they affect synaptic function and how altered local translational control contributes to a form of human mental retardation, Fragile X Syndrome.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
