Superactivation of AMPA receptors by auxiliary proteins [PDF]
Nature Communications, 2016 AbstractGlutamate receptors form complexes in the brain with auxiliary proteins, which control their activity during fast synaptic transmission through a seemingly bewildering array of effects. Here we devise a way to isolate the activation of complexes using polyamines, which enables us to show that transmembrane AMPA receptor regulatory proteins ...

Structure and function of AMPA receptors [PDF]
The Journal of Physiology, 2004 The application of X‐ray diffraction has allowed the structure of the ligand‐binding core of AMPA receptors to be determined. Here I review the insights that this has given into the molecular mechanisms of activation and desensitization of these receptors.

Single-Particle Tracking of AMPA Receptor-Containing Vesicles
Bio-ProtocolAMPA-type receptors are transported large distances to support synaptic plasticity at distal dendritic locations. Studying the motion of AMPA receptor+ vesicles can improve our understanding of the mechanisms that underlie learning and memory ...

The tetraspanin TSPAN5 regulates AMPAR exocytosis by interacting with the AP4 complex
eLife, 2023 Intracellular trafficking of AMPA receptors is a tightly regulated process which involves several adaptor proteins, and is crucial for the activity of excitatory synapses both in basal conditions and during synaptic plasticity.

Pharmacological analysis of ionotropic glutamate receptor function in neuronal circuits of the zebrafish olfactory bulb. [PDF]
PLoS ONE, 2008 Although synaptic functions of ionotropic glutamate receptors in the olfactory bulb have been studied in vitro, their roles in pattern processing in the intact system remain controversial.

Recent Findings on AMPA Receptor Recycling [PDF]
Frontiers in Cellular Neuroscience, 2018 α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPA-Rs) are tetrameric protein complexes that mediate most of the fast-excitatory transmission in response to the neurotransmitter glutamate in neurons. The abundance of AMPA-Rs at the surface of excitatory synapses establishes the strength of the response to glutamate. It is thus evident

AMPA receptor subunit expression in the endoplasmic reticulum in frontal cortex of elderly patients with schizophrenia. [PDF]
PLoS ONE, 2012 Several lines of evidence indicate altered trafficking of α-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate (AMPA) receptors in schizophrenia. Previous reports have shown potential changes in the trafficking of AMPA receptors based on subunit expression

Desensitization dynamics of the AMPA receptor
Structure, 2023 To perform their physiological functions, amino methyl propionic acid receptors (AMPARs) cycle through active, resting, and desensitized states, and dysfunction in AMPAR activity is associated with various neurological disorders. Transitions among AMPAR functional states, however, are largely uncharacterized at atomic resolution and are difficult to ...

Assembly and Stoichiometry of the AMPA Receptor and Transmembrane AMPA Receptor Regulatory Protein Complex [PDF]
The Journal of Neuroscience, 2010 Glutamate is a major excitatory neurotransmitter in the vertebrate brain. AMPA-type glutamate receptors mediate fast excitatory transmission. AMPA receptors assemble with transmembrane AMPA receptor regulatory protein (TARP) auxiliary subunits and function as native ion channels.
