Five rare missense mutations in the GRIN2B gene are not associated with schizophrenia or autism spectrum disorder in a Japanese population.
NR4A1 (show NR4A1 Proteins) knockdown partly decreased surface NR2B by promoting NR2B internalization.
This review showed that GRIN2B associate with Obsessive-compulsive disorder.
GRIN2B polymorphism was associated with a twofold increase in odds of a Suicide Attempts in Alcohol-dependent individuals.
GRIN2B encephalopathy is also frequently associated with movement disorder, cortical visual impairment and malformation of cortical development revealing novel phenotypic consequences of channelopathies.
mutations of the human NMDAR (show GRIN1 Proteins) were investigated and studied their consequences with kinetic modelling and electrophysiology.
The polymorphisms in HTR2A and GRIN2B were significantly associated with increased risk of chronic obstructive pulmonary disease.
In vitro DNA-binding and reporter gene assays of different allele combinations in transfected cells showed that the A allele was a gain-of-function variant associated with increasing GRIN2B mRNA levels
Polymorphism C366G of gene GRIN2B and verbal episodic memory: No association with schizophrenia
These results indicate these individuals may have suffered neurodevelopmental deficits as a result of the decreased presence of GluN1 (show GRIN1 Proteins)-G620R/GluN2B complexes on the neuronal surface during embryonic brain development and reduced current responses of GluN1 (show GRIN1 Proteins)-G620R-containing NMDARs after birth.
chronic KOR (show OPRK1 Proteins) activation increased phosphorylation of NR2B subunit of NMDA at tyrosine 1472 (pNR2B NMDA) in the hippocampus, but not in the cortex.
Study generated the Cdkl5 (show CDKL5 Proteins) KO mice, and identified hyperexcitability in response to NMDA and postsynaptic overaccumulation of GluN2B-containing NMDARs in the hippocampus. The GluN2B-selective antagonist ifenprodil abrogated the NMDA-induced hyperexcitability of Cdkl5 (show CDKL5 Proteins) KO mice. These data indicate that CDKL5 (show CDKL5 Proteins) plays an important role in controlling postsynaptic localization of the GluN2B-SAP102 (show DLG3 Proteins) complex in the hippocampus.
APP (show APP Proteins) intracellular domain increase in mature neurons, as reported in Alzheimer's disease, alters synaptic NMDAR (show GRIN1 Proteins) composition to an immature-like GluN2B-rich profile. This disrupts synaptic signal integration, via over-activation of SK channels, and synapse plasticity.
The induction of a conditional forebrain-specific haploinsufficiency of GluN2B in transgenic model mice reverses the pathophysiological changes in hippocampal synaptic plasticity in a mouse model of Alzheimer's disease (AD). These results provide further evidence for the involvement of the glutamatergic system in AD pathology and emphasize the GluN2B subunit as a potential target for AD treatment.
activity-based anorexia resilience, quantified as suppression of hyperactivity, correlated strongly with reserve pools of NR2A (show GRIN2A Proteins)-NMDA receptors in spine cytoplasm
Negative regulation of REST on NR2B in spinal cord takes part in the exacerbation of bone cancer pain.
results demonstrated that phosphorylation level of S1284 in GluN2B was regulated by acute stress
study are the first to demonstrate that phosphorylation of GluN2B subunit at Tyr1472 is important for trigeminal transmission of itch and suggest that the NMDA receptor activation occurs upstream of the receptor of gastrin-releasing peptide (GRP)-GRP (show GRP Proteins) receptor pathway
GluN2B gene deletion mice consumed significantly less alcohol, than non-mutant controls.
N-methyl-D-aspartate (NMDA) receptors are a class of ionotropic glutamate receptors. NMDA receptor channel has been shown to be involved in long-term potentiation, an activity-dependent increase in the efficiency of synaptic transmission thought to underlie certain kinds of memory and learning. NMDA receptor channels are heteromers composed of three different subunits: NR1 (GRIN1), NR2 (GRIN2A, GRIN2B, GRIN2C, or GRIN2D) and NR3 (GRIN3A or GRIN3B). The NR2 subunit acts as the agonist binding site for glutamate. This receptor is the predominant excitatory neurotransmitter receptor in the mammalian brain.
