Yuan et al., Shanghai, China. In Neurobiol Learn Mem, Jan 2016
In addition, molecular and cellular studies revealed several alterations including: (1) the enhanced ratio of excitatory to inhibitory synapses; (2) increased expression of NMDA receptors NR2A; (3) enhanced activation of ERK signaling; (4) lowered number of the mushroom- and bifurcate-shaped dendritic spines in NP65 KO mice.
[The developmental switch of visual cortex NMDA receptor NR2 subunits and its implications for visual plasticity].
Zhao et al., Tianjin, China. In Zhonghua Yan Ke Za Zhi, Jun 2015
These tetrameric receptors consist of two obligatory NR1 subunits and two regulatory subunits, usually a combination of NR2A and NR2B.

Mak et al., Singapore, Singapore. In Int J Mol Sci, 2014
This review will focus on the potential pathogenic factors involved in NPSLE, including anti-N-methyl-d-aspartate receptor subunit NR2A/B (anti-NR2A/B) antibodies, matrix metalloproteinase-9, neutrophil extracellular traps and pro-inflammatory mediators.
Meta-analysis of the association between N-methyl-d-aspartate receptor antibodies and schizophrenia, schizoaffective disorder, bipolar disorder, and major depressive disorder.
Najjar et al., New York City, United States. In Schizophr Res, 2014
Seropositive participants in psychiatric groups had various combinations of IgG, IgM, and IgA class antibodies against NR1, NR1/NR2B, and NR2A/NR2B subunits.
Involvement of NR1, NR2A different expression in brain regions in anxiety-like behavior of prenatally stressed offspring.
Zhu et al., Xi'an, China. In Behav Brain Res, 2013
Additionally, expression of NR1 and NR2A subunit of N-methyl-D-aspartate receptor (NMDAR) in the hippocampus (HIP), prefrontal cortex (PFC) and striatum (STR) was studied.

Casein kinase 2-mediated synaptic GluN2A up-regulation increases N-methyl-D-aspartate receptor activity and excitability of hypothalamic neurons in hypertension.
Pan et al., Houston, United States. In J Biol Chem, 2012
CK2-mediated GluN2B phosphorylation contributes to increased synaptic GluN2A, which potentiates pre- and postsynaptic NMDAR activity and the excitability of PVN presympathetic neurons in hypertension.
Identification of N-methyl-D-aspartic acid (NMDA) receptor subtype-specific binding sites that mediate direct interactions with scaffold protein PSD-95.
Stephenson et al., London, United Kingdom. In J Biol Chem, 2012
We show that NR2A subunits interact directly with PSD-95 via the C-terminal ESDV motif and additionally via an Src homology 3 domain-binding motif that associates with the Src homology 3 domain of PSD-95.
NR2A and NR2B subunits differentially mediate MAP kinase signaling and mitochondrial morphology following excitotoxic insult.

Dityatev et al., Hamburg, Germany. In J Neurosci, 2012
Inhibition of the GluN2A subtype reduces long term potentiation to the same level in NCAM-deficient and wild-type (NCAM-positive) littermate mice and abolishes the rescue by d-cycloserine in NCAM-deficient mice.

Paoletti et al., Paris, France. In Nature, 2009
NMDARs exist as multiple subtypes with distinct pharmacological and biophysical properties that are largely determined by the type of NR2 subunit (NR2A to NR2D) incorporated in the heteromeric NR1/NR2 complex.
