N-methyl-D-aspartate (NMDA) receptor plays important roles in learning and memory. NMDA receptors are a tetramer that consists of two glycine-binding subunits GluN1, two glutamate-binding subunits (i.e., GluN2A, GluN2B, GluN2C, and GluN2D), a combination of a GluN2 subunit and glycine-binding GluN3 subunit (i.e., GluN3A or GluN3B), or two GluN3 subunits. Recent studies revealed that the specifi...
The amino acids L-glutamate and glycine are essential agonists of the excitatory NMDA receptor, a subtype of the ionotropic glutamate receptor family. The native NMDA receptor is composed of two types of homologous membrane-spanning subunits, NR1 and NR2. Here, the numbers of glycine-binding NR1 and glutamate-binding NR2 subunits in the NMDA receptor hetero-oligomer were determined by coexpress...
The neuronal transporter excitatory amino acid carrier 1 (EAAC1) is enriched in perisynaptic regions, where it may regulate synaptic spillover of glutamate. In this study we examined potential interactions between EAAC1 and ionotropic glutamate receptors. N-Methyl-D-aspartate (NMDA) receptor subunits NR1, NR2A, and NR2B, but not the alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid rece...
Converging evidence suggests that salience-associated modulation of behavior is mediated by the release of monoamines and that monoaminergic activation of D(1)/D(5) receptors is required for normal hippocampal-dependent learning and memory. However, it is not understood how D(1)/D(5) modulation of hippocampal circuits can affect salience-associated learning and memory. We have observed in CA1 p...
Modification of NMDA receptor function and trafficking contributes to the regulation of synaptic transmission and is important for several forms of synaptic plasticity. Here, we report that NMDA receptor subunits NR2A and NR2B have two distinct clusters of palmitoylation sites in their C-terminal region. Palmitoylation within the first cluster on a membrane-proximal region increases tyrosine ph...
OBJECTIVE To assess whether N-methyl-D-aspartate (NMDA) receptor (NR) or oestrogen receptor (OR) expression plays a role in the differences that temporalis muscle afferent fibres are less sensitive to peripheral receptor activation than masseter muscle afferent fibres and do not exhibit sex-related differences in NMDA-evoked discharge. METHODS Immunohistochemical techniques were used to exami...
N-Methyl-D-aspartate (NMDA) receptors are a member of the ionotropic glutamate receptor family, ligandgated ion channels that mediate the majority of excitatory neurotransmission in the mammalian CNS. They are expressed primarily in the CNS but also in peripheral locations such as pancreatic islet cells, sensory nerve terminals in skin and cardiac ganglia1. Seven subunits of the NMDA receptor h...
Live-trapping of animals in natural populations is one of the main ways to determine population processes. We examined the effects of live-trapping on the expression of N-methyl-d-aspartate (NMDA) receptor subunits in the hippocampus of snowshoe hares. Snowshoe hares were obtained either with or without the stress of live-trapping. The CA1, CA3 and dentate gyrus were dissected and analyzed for ...
The N-methyla-aspartate R1 (NMDA Rl), NMDA R2A, and NMDA R2C subunits were expressed transiently in double or triple combinations in human embryonic kidney (HEK) 293 cells. The biochemical and pharmacological properties of the cloned receptors were compared with those of adult mouse forebrain and cerebellum. Under conditions established for maximal expression, cotransfection of the NMDARl and R...
