Component of NMDA receptor complexes that function as heterotetrameric, ligand-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium. Channel activation requires binding of the neurotransmitter glutamate to the epsilon subunit, glycine binding to the zeta subunit, plus membrane depolarization to eliminate channel inhibition by Mg(2+). Sensitivity to glutamate and channel kinetics depend on the subunit composition (Probable). Plays a role in regulating the balance between excitatory and inhibitory activity of pyramidal neurons in the prefrontal cortex. Contributes to the slow phase of excitatory postsynaptic current, long-term synaptic potentiation, and learning.

- ultra-rare variants with loss of function (frameshift, nonsense or splice site) in NMDARs genes like GRIN2C and GRIN2D may contribute to possible risk of schizophrenia PMID: 29317596
- Findings indicate that SNPs in the GRIN2C gene is associated with altered cue-induced brain activation that is related to craving for alcohol and relapse risk. PMID: 26289945
- these findings highlight the isoform-specific structural and functional differences within the 14-3-3 family of proteins, which determine GluN2C binding and its essential role in targeting the receptor to the cell surface PMID: 26229101
- The major depression subjects exhibited significantly higher expression levels of the NMDA receptor subunit genes GRIN2C. PMID: 24925192
- TNFalpha significantly upregulates NMDA-R2C mRNA expression, in differentiated, confluent, normal keratinocytes but not in involved or uninvolved psoriatic keratinocyte monolayers PMID: 24102971
- The authors identified and cloned sequences of NMDA receptor subunits 2A, 2B, and 2C from rat. They characterized the properties of the receptors composed of heteromeric 1-2A and heteromeric 1-2C and found that the latter had reduced sensitivity to magnesium and smaller conductance compared to the former.

- Functional compensation could occur to counteract the loss of one allele in GRIN2C and GRIN3 family genes. PMID: 22833210
