Abstract : Phosphorylation of the glutamate receptor is an important mechanism of synaptic plasticity. Here, we show that the C terminus of GluR2 of the α‐amino‐3‐hydroxy‐5‐methylisoxazole‐4‐propionate (AMPA) receptor is phosphorylated by protein kinase C and that serine‐880 is the major phosphorylation site. This phosphorylation also occurs in human embryonic kidney (HEK) cells by addition of 12‐O‐tetradecanoylphorbol 13‐acetate. Our immunoprecipitation experiment revealed that the… 
Phosphorylation‐dependent interactions of α‐Actinin‐1/IQGAP1 with the AMPA receptor subunit GluR4
The data indicate that activity‐dependent phosphorylation of GluR4 may regulate its synaptic targeting through phosphorylated‐dependent interactions with α‐Actinin‐1 and IQGAP1.
Phosphorylation of glutamate receptors: A potential mechanism for the regulation of receptor function and psychostimulant action
Emerging evidence shows that psychostimulants may modulate NMDAR and AMPAR function through the phosphorylation mechanism to shape the excitatory synaptic plasticity related to additive properties of drugs of abuse.

The data suggest that the phosphorylation of AMPA receptor GluR2 subunit at S880 is subject to the upregulation by the stimulation of group I mGluRs.
Phosphorylation of GluR4 AMPA‐type glutamate receptor subunit by protein kinase C in cultured retina amacrine neurons
GluR4 is phosphorylated upon PKC activation and/or stimulation of AMPA receptors in cultured amacrine cells, and AMPA receptor activation with kainate in cultured chick amacine cells leads to translocation of conventional and novel PKC isoforms to the cell membrane, suggesting that PKC could be activated upon AMPAceptor stimulation in these cells.
Phosphorylation of Glutamate Receptor Interacting Protein 1 Regulates Surface Expression of Glutamate Receptors*
This work shows that an about 85-kDa protein kinase phosphorylates GRIP1 on serine 917, and identifies an important regulatory mechanism in the trafficking of AMPAR subunits between internal compartments and the plasma membrane.
PIKE‐mediated PI3‐kinase activity is required for AMPA receptor surface expression
It is shown that PIKE (phosphoinositide 3‐kinase enhancer) GTPases regulate neuronal AMPAR activity by promoting GluA2/GRIP1 association and PIKE‐L directly interacts with both GLUA2 and GRIP1 and forms a tertiary complex upon glycine‐induced NMDA receptor activation.
Phosphorylation of the AMPA Receptor Subunit GluR2 Differentially Regulates Its Interaction with PDZ Domain-Containing Proteins
It is shown that PKC phosphorylation of the AMPA receptor GluR2 subunit differentially modulates its interaction with the PDZ domain-containing proteins GRIP1 and PICK1.
Protein Kinase Cγ Associates Directly with the GluR4 α-Amino-3-hydroxy-5-methyl-4-isoxazole Propionate Receptor Subunit
The results suggest that PKCγ binds directly to GLUR4, thereby modulating the function of GluR4-containing AMPA receptors.
Regulation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor trafficking through PKA phosphorylation of the Glu receptor 1 subunit
It is shown that phosphorylation of the GluR1 subunit on serine 845 by PKA is required for PKA-induced increases in AMPA receptor cell-surface expression because it promotes receptor insertion and decreases receptor endocytosis.


Cyclic AMP and synaptic activity-dependent phosphorylation of AMPA- preferring glutamate receptors
The results indicate that AMPA receptors containing the GluR1 subunit may be regulated by extracellular signals working through the cAMP second messenger system as well as by synaptic activity, possibly acting through protein kinase C.
Enhanced tyrosine phosphorylation of the 2B subunit of the N-methyl-D-aspartate receptor in long-term potentiation.
It is shown that, after induction of LTP in the dentate gyrus of anesthetized adult rats, there is an increase in the tyrosine phosphorylation of the 2B subunit of the N-methyl-D-aspartate (NMDA) receptor (NR2B), as well as several other unidentified proteins.
Identification of the Ca2+/Calmodulin-dependent Protein Kinase II Regulatory Phosphorylation Site in the α-Amino-3-hydroxyl-5-methyl4-isoxazole-propionate-type Glutamate Receptor*
The Ser831 site is specific to GluR1, and CaM-KII did not phosphorylate or potentiate current in cells expressing GluGluR2, emphasizing the importance of the GLUR1 subunit in this regulatory mechanism.
GRIP: a synaptic PDZ domain-containing protein that interacts with AMPA receptors
GRIP is a new member of the PDZ domain-containing protein family which has seven PDZ domains and no catalytic domain and appears to serve as an adapter protein that links AMPA receptors to other proteins and may be critical for the clustering of AMPA receptor at excitatory synapses in the brain.
Competitive binding of α-actinin and calmodulin to the NMDA receptor
The mechanisms by which neurotransmitter receptors are immobilized at postsynaptic sites in neurons are largely unknown. The activity of NMDA (N-methyl-D-aspartate) receptors is mechanosensitive1 and
The glycine binding site of the N-methyl-D-aspartate receptor subunit NR1: identification of novel determinants of co-agonist potentiation in the extracellular M3-M4 loop region.
Results indicate that the M3-M4 loop is part of the ligand-binding pocket of the NR1 subunit and provide the basis for a refined model of the glycine-binding site of the NMDA receptor.
Protein kinases and phosphatase inhibitors mediating long-term desensitization of glutamate receptors in cerebellar Purkinje cells
Calcium/calmodulin-dependent kinase II and long-term potentiation enhance synaptic transmission by the same mechanism.
It is indicated that CaM-K II alone is sufficient to augment synaptic strength and that this enhancement shares the same underlying mechanism as the enhancement observed with LTP.
Glycine-receptor activation is required for receptor clustering in spinal neurons
It is shown that the competitive GlyR antagonist strychnine and L-type Ca2+-channel blockers inhibit the accumulation of GlyR and gephyrin at postsynaptic membrane areas in cultured rat spinal neurons.
