NMDA receptor surface mobility depends on NR2A-2B subunits.
The NR2 subunit composition of NMDA receptors (NMDARs) varies during development, and this change is important in NMDAR-dependent signaling. In particular, synaptic NMDAR switch from containing mostly NR2B subunit to a mixture of NR2B and NR2A subunits. The pathways by which neurons differentially traffic NR2A- and NR2B-containing NMDARs are poorly understood. Using single-particle and -molecul...
متن کامل2B or Not 2B: A Tail of Two NMDA Receptor Subunits
N-methyl-D-aspartate (NMDA) receptor activation can be neuroprotective or neurotoxic depending on receptor location. In this issue of Neuron, Martel et al. (2012) demonstrate that the C-terminal of NMDA receptor subunits also contributes critically to excitotoxicity. NMDA receptor subunits containing the GluN2B C-terminal are more lethal than those containing the GluN2A tails, regardless of loc...
متن کاملCloning and Phylogenetic Analysis of NMDA Receptor Subunits NR1, NR2A and NR2B in Xenopus laevis Tadpoles
N-methyl-d-aspartate receptors (NMDARs) play an important role in many aspects of nervous system function such as synaptic plasticity and neuronal development. NMDARs are heteromers consisting of an obligate NR1 and most commonly one or two kinds of NR2 subunits. While the receptors have been well characterized in some vertebrate and invertebrate systems, information about NMDARs in Xenopus lae...
متن کاملLateral hypothalamic NMDA receptor subunits NR2A and/or NR2B mediate eating: immunochemical/behavioral evidence.
Cells within the lateral hypothalamic area (LHA) are important in eating control. Glutamate or its analogs, kainic acid (KA) and N-methyl-d-aspartate (NMDA), elicit intense eating when microinjected there, and, conversely, LHA-administered NMDA receptor antagonists suppress deprivation- and NMDA-elicited eating. The subunit composition of LHA NMDA receptors (NMDA-Rs) mediating feeding, however,...
متن کاملPostnatal switching of NMDA receptor subunits from NR2B to NR2A in rat facial motor neurons.
The subunit composition of N-methyl-D-aspartate (NMDA) receptors affects their function under normal and pathological conditions. Functional NMDA receptors are expressed in lower motor neurons, but their subunit composition has not been defined. Here, we employed electrophysiology, quantitative PCR, and immunohistochemistry to investigate the subunit composition of NMDA receptors in postnatal m...
