Retaining Synaptic AMPARs [PDF]
Neuron, 2007 Endocytosis, exocytosis, and lateral diffusion are key mechanisms for AMPA receptor trafficking. Endocytosis of AMPARs and other postsynaptic proteins has been proposed to occur at specific endocytic zones (EZs), but the mechanisms that regulate this process are not at all clear. In this issue of Neuron, Lu et al.
