Metabotropic glutamate receptors trigger postsynaptic protein synthesis.
K+ depolarization or addition of glutamate to a synaptoneurosome preparation triggers a rapid increase in size of polyribosomal aggregates isolated by centrifugation of lysate through 1 M sucrose. The profile of response to the glutamate analogues quisqualate, ibotenate, and 1-aminocyclopentane-1,3-dicarboxylate corresponds to that of metabotropic receptors. Glutamate stimulation is mimicked by...
متن کاملFunctional cooperation of metabotropic adenosine and glutamate receptors regulates postsynaptic plasticity in the cerebellum.
G-protein-coupled receptors (GPCRs) may form heteromeric complexes and cooperatively mediate cellular responses. Although heteromeric GPCR complexes are suggested to occur in many neurons, their contribution to neuronal function remains unclear. We address this question using two GPCRs expressed in cerebellar Purkinje cells: adenosine A1 receptor (A1R), which regulates neurotransmitter release ...
متن کاملPostnatal developmental alterations in the locus coeruleus neuronal fast excitatory postsynaptic currents mediated by ionotropic glutamate receptors of rat
Introduction: In the present work, spontaneous postsynaptic currents were assessed to investigate the postnatal development of excitatory postsynaptic currents in locus coeruleus neurons. Methods: In this study, AMPA and NMDA receptor-mediated spontaneous synaptic currents in the neurons of locus coeruleus were assessed using whole cell voltage-clamp recording during the first three weeks. ...
متن کاملGlutamate Receptors Are Selectively Targeted to Postsynaptic Sites in Neurons
The objective of the present study was to determine if a neuron that expresses multiple glutamate receptors targets the same receptors to all glutamatergic postsynaptic populations, or if the receptors are differentially targeted to specific postsynaptic populations. As a model for this study, we chose the fusiform cell of the dorsal cochlear nucleus. This neuron expresses multiple glutamate re...
متن کاملFunctional Organization of the GluR1 Glutamate Receptor
The GluR1 glutamate receptor subunit is expressed in most brain areas and plays a major role in excitatory synaptic transmission. We cloned and sequenced 5 kilobase pairs of the rat GluR1 promoter and identified multiple transcriptional start sites between 2295 and 2202 (relative to the first ATG). Similar to other glutamate receptor subunit promoters, the GluR1 promoter lacks TATA and CAAT ele...
