TLDR
An overview of the catalogue of AMPAR interacting proteins and how they contribute to the complex biology of this central glutamate receptor can be found in this article, where an array of transmembrane proteins operate as auxiliary subunits that in addition to receptor trafficking and stabilization also substantially impact AMPAR gating and pharmacology.About:

Mechanisms underlying TARP modulation of the GluA1/2-γ8 AMPA receptor
Beatriz Herguedas,Bianka Kőhegyi,Jan-Niklas Dohrke,Jake F. Watson,Danyang Zhang,Hinze Ho,Saher A. Shaikh,Remigijus Lape,James Krieger,Ingo H. Greger +9 more
TL;DR: In this paper , electron cryo-microscopy structures of the GluA1/2 TARP-γ8 complex, in both open and desensitized states (at 3.5 Å), reveal state-selective engagement of the LBDs by the large TARPγ8 loop ('β1'), elucidating how this TARP stabilizes specific gating states.

Influence of the TARP γ8-Selective Negative Allosteric Modulator JNJ-55511118 on AMPA Receptor Gating and Channel Conductance
TL;DR: In this paper , a patch-clamp electrophysiological recording from heterologously expressed AMPARs was used to characterize the actions of the γ8-selective AMPAR inhibitor JNJ-55511118 on GluA2(Q) receptors expressed in HEK cells.

Diversity of AMPA Receptor Ligands: Chemotypes, Binding Modes, Mechanisms of Action, and Therapeutic Effects
TL;DR: A review of AMPA receptor ligands can be found in this paper , where the structural diversity of new chemotypes of agonists, competitive AMPA receptors, positive and negative allosteric modulators, transmembrane AMPA regulatory protein (TARP) dependent allosterics, ion channel blockers as well as their binding sites are discussed.
Journal ArticleDOI
The many faces of the AMPA-type ionotropic glutamate receptor
TL;DR: For instance, the authors provides a series of issues dedicated to each member of the Glutamate receptor superfamily that includes both ionotropic and metabotropic classes, including NMDA, AMPA-and kainate-selective iGluRs.

Synaptic strength regulated by palmitate cycling on PSD-95
Alaa El-Husseini,Eric Schnell,Srikanth Dakoji,Neal T. Sweeney,Qiang Zhou,Oliver Prange,Catherine Gauthier-Campbell,Andrea Aguilera-Moreno,Roger A. Nicoll,David S. Bredt +9 more
TL;DR: It is found that palmitate cycling on PSD-95 can regulate synaptic strength and regulates aspects of activity-dependent plasticity, and that rapid glutamate-mediated AMPA receptor internalization requires depalmitoylation of PSd-95.
Journal ArticleDOI
The Interaction between Stargazin and PSD-95 Regulates AMPA Receptor Surface Trafficking
TL;DR: It is shown, using single quantum dot and FRAP imaging in live hippocampal neurons, that exchange of AMPAR by lateral diffusion between extrasynaptic and synaptic sites mostly depends on the interaction of Stargazin with PSD-95 and not upon the GluR2 AMPAR subunit C terminus.

NSF Binding to GluR2 Regulates Synaptic Transmission
Atsushi Nishimune,John T.R. Isaac,Elek Molnár,Jacques Noël,S.Russell Nash,Mitsuo Tagaya,Graham L. Collingridge,Shigetada Nakanishi,Jeremy M. Henley,Jeremy M. Henley +9 more
TL;DR: A previously unsuspected direct interaction in the postsynaptic neuron between two major proteins involved in synaptic transmission is demonstrated and a rapid NSF-dependent modulation of AMPA receptor function is suggested.
Journal ArticleDOI
The AMPA Receptor Code of Synaptic Plasticity.
TL;DR: The AMPAR code suggests that AMPAR variants will be predictive of the types and extent of synaptic plasticity that can occur and that a hierarchy exists such that certain AMPARs will be disproportionally recruited to synapses during LTP/homeostatic scaling up, or removed during LTD/homeOSTatic scaling down.

cornichon and the EGF receptor signaling process are necessary for both anterior-posterior and dorsal-ventral pattern formation in Drosophila
TL;DR: Mutations in all three genes prevent the formation of a correctly polarized microtubule cytoskeleton required for proper localization of the anterior and posterior determinants bicoid and oskar and for the asymmetric positioning of the oocyte nucleus.
