Over the years there have been many different nomenclature schemes for the ionotropic glutamate receptors. The following table gives the new (and final) nomenclature, agreed in Paris in 2008 by the IUHPAR (International Union of basic and clinical pharmacology).
| NMDA Receptors | AMPA Receptors | Kainate Receptors | Delta Receptors |
|---|---|---|---|
| NR1 = GluN1 NR2A = GluN2A NR2B = GluN2B NR2C = GluN2C NR2D = GluN2D NR3A = GluN3A NR3B = GluN3B |
GluRA = GluR1 = GluA1 GluRB = GluR2 = GluA2 GluRC = GluR3 = GluA3 GluRD = GluR4 = GluA4 |
GluR5 = GLUK5 = GluK1 GluR6 = GLUK6 = GluK2 GluR7 = GLUK7 = GluK3 KA1 = GLUK1 = GluK4 KA2 = GLUK2 = GluK5 |
δ1 = GluD1 δ2 = GluD2 |
