Subunit-specific gating controls rat NR1/NR2A and NR1/NR2B NMDA channel kinetics and synaptic signalling profiles.

NR2A and NR2B are the predominant NR2 NMDA receptor subunits expressed in cortex and hippocampus. The relative expression level of NR2A and NR2B is regulated developmentally and these two subunits have been suggested to play distinct roles in long-term synaptic plasticity. We have used patch-clamp recording of recombinant NMDA receptors expressed in HEK293 cells to characterize the activation p...

Subunit-specific Contribution of Pore-forming Domains to NMDA Receptor Channel Structure and Gating

N-methyl-D-aspartate receptors (NMDARs) are ligand-gated ion channels that contribute to fundamental physiological processes such as learning and memory and, when dysfunctional, to pathophysiological conditions such as neurodegenerative diseases, stroke, and mental illness. NMDARs are obligate heteromultimers typically composed of NR1 and NR2 subunits with the different subunits underlying the ...

EphB controls NMDA receptor function and synaptic targeting in a subunit-specific manner.

Dynamic regulation of the localization and function of NMDA receptors (NMDARs) is critical for synaptic development and function. The composition and localization of NMDAR subunits at synapses are tightly regulated and can influence the ability of individual synapses to undergo long-lasting changes in response to stimuli. Here, we examine mechanisms by which EphB2, a receptor tyrosine kinase th...

NMDA receptor subunit gating--uncovered.

Kinetically distinct contributions of NMDA receptor NR1 and NR2 subunits to channel gating have recently been inferred by Banke and Traynelis from single-channel recordings of recombinant NR1–NR2B receptors. The results suggest a new mechanism for receptor activation that will enhance our insight into excitatory synaptic transmission in the brain. In the post-genomic era, this represents an exc...

Zinc effects on NMDA receptor gating kinetics.

Zinc accumulates in the synaptic vesicles of certain glutamatergic forebrain neurons and modulates neuronal excitability and synaptic plasticity by multiple poorly understood mechanisms. Zinc directly inhibits NMDA-sensitive glutamate-gated channels by two separate mechanisms: high-affinity binding to N-terminal domains of GluN2A subunits reduces channel open probability, and low-affinity volta...
