Heteromeric NMDA Receptors: Molecular and Functional Distinction of Subtypes
The N-methyl d-aspartate (NMDA) receptor subtype of glutamate-gated ion channels possesses high calcium permeability and unique voltage-dependent sensitivity to magnesium and is modulated by glycine.… Expand

A molecular determinant for submillisecond desensitization in glutamate receptors.
The decay of excitatory postsynaptic currents in central neurons mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionate (AMPA) receptors is likely to be shaped either by receptor… Expand

Single-channel conductances of NMDA receptors expressed from cloned cDNAs: comparison with native receptors
To cast light on the subunit composition of native NMDA-type glutamate receptors, four cloned subunits of the NMDA receptor have been expressed, in pairs, in Xenopus oocytes, and their single-channel… Expand

Multiple Structural Elements Determine Subunit Specificity of Mg2+ Block in NMDA Receptor Channels
In NMDA receptor channels, subtype-specific differences of Mg2+ block are determined by the NR2 subunits. Channels assembled from the NR1-NR2A or NR1-NR2B subunits are blocked more strongly than… Expand

Control by asparagine residues of calcium permeability and magnesium blockade in the NMDA receptor.
The N-methyl-D-aspartate (NMDA) receptor forms a cation-selective channel with a high calcium permeability and sensitivity to channel block by extracellular magnesium. These properties, which are… Expand

Global Identification and Characterization of Both O-GlcNAcylation and Phosphorylation at the Murine Synapse*
O-linked N-acetylglucosamine (O-GlcNAc) is a dynamic, reversible monosaccharide modifier of serine and threonine residues on intracellular protein domains. Crosstalk between O-GlcNAcylation and… Expand

Neuron-glia communication via EphA4/ephrin-A3 modulates LTP through glial glutamate transport
Astrocytes are critical participants in synapse development and function, but their role in synaptic plasticity is unclear. Eph receptors and their ephrin ligands have been suggested to regulate… Expand

O-Linked N-Acetylglucosamine Proteomics of Postsynaptic Density Preparations Using Lectin Weak Affinity Chromatography and Mass Spectrometry*S
O-GlcNAc is a widespread dynamic carbohydrate modification of cytosolic and nuclear proteins with features analogous to phosphorylation. O-GlcNAc acts critically in many cellular processes, including… Expand

Identification of Amino Acid Residues of the NR2A Subunit That Control Glutamate Potency in Recombinant NR1/NR2A NMDA Receptors
The NMDA type of ligand-gated glutamate receptor requires the presence of both glutamate and glycine for gating. These receptors are hetero-oligomers of NR1 and NR2 subunits. Previously it was… Expand

Structural and pharmacological characterization of the major brain nicotinic acetylcholine receptor subtype stably expressed in mouse fibroblasts.
Previously, we purified the predominant subtype of brain nicotinic acetylcholine receptor (AChR), analyzed its structure, and found that it was composed of two kinds of subunit, with sequences… Expand
