Kainate receptor trafficking: physiological roles and molecular mechanisms.
Recently, there has been intense interest in the mechanisms regulating the trafficking and synaptic targeting of kainate receptors in neurons. This topic is still in its infancy when compared with studies of trafficking of other ionotropic glutamate receptors; however, it is already clear that mechanisms exist for subunit- and splice variant-specific trafficking of kainate receptors. There is also enormous diversity of kainate receptor targeting, with the best-studied neurons in this regard being hippocampal CA3 pyramidal neurons and CA1 GABAergic interneurons. This review summarizes the current state of knowledge on this topic, focusing on the molecular mechanisms of kainate receptor trafficking and the potential for these mechanisms to regulate neuronal kainate receptor function.
