N-methyl-D-aspartate receptors (NMDARs) are ligand-gated ionotropic glutamate receptors that mediate excitatory synaptic transmission and are important for many aspects of nervous system function including: synaptic plasticity; learning and memory; neuronal development and circuit formation. NMDARs have also been implicated in various neuronal disorders. NMDARs are heteromers consisting of an obligate NR1 and most commonly one or two kinds of NR2 subunits or occasionally NR3 subunits.

NR2B is the predominant subunit found in the postnatal brain, however over time NRA2 levels increase and eventually outnumber NR2B subunits in a process known as the NR2B-NR2A developmental switch. The greater ratios of the NR2B subunit in post-natal brains leads to NMDA receptors which remain open longer compared to those with more NR2A subunits, and may be related to the greater memory abilities in the immediate postnatal period compared to late in life.

The phosphorylation of NR2B is closely linked to its transport and the phosphorylation of NR2B at serine residue at position 1303 is an initial step of NMDA‐induced excitotoxicity. NR2B is phosphorylated at Ser1303 by protein kinase C (PKC) and is dephosphorylated by protein phosphatase 1 (PP1).

The involvement of NMDAR in the central nervous system (CNS) has become a focus area for neurodegenerative diseases such as Alzheimer's disease, epilepsy and ischemic neuronal cell death.
