The molecular mechanisms of its regulation remain poorly understood, however. Here we show by biochemical and atomic force microscopy analyses that NEEP21, a neuronal endosomal protein necessary for receptor recycling including AMPAR, is associated with the scaffolding protein GRIP1 and the AMPAR subunit GluR2. Moreover, the interaction between NEEP21 and GRIP1 is regulated by neuronal activity. Expression of a NEEP21 fragment containing the GRIP1-binding site decreases surface GluR2 levels and delays recycling of internalized GluR2, which accumulates in early endosomes and lysosomes. Infusion of this fragment into pyramidal neurons of hippocampal slices induces inward rectification of AMPAR-mediated synaptic responses, suggesting decreased GluR2 expression at synapses. These results indicate that NEEP21-GRIP1 binding is crucial for GluR2-AMPAR sorting through endosomes and their recruitment to the plasma membrane, providing a first molecular mechanism to differentially regulate AMPAR subunit cycling in internal compartments."xsd:string |
