Ionotropic glutamate receptor nomenclature

 Ionotropic glutamate receptor nomenclature can be confusing, so here is a handy table to guide you through the past and present nomenclature. Bold text indicates the latest nomenclature adopted by IUHPAR (International Union of basic and clinical pharmacology) in 2008.

NMDA Receptors 

• NR1 = GluN1
• NR2A = GluN2A
• NR2B = GluN2B
• NR2C = GluN2C
• NR2D = GluN2D
• NR3A = GluN3A
• NR3B = GluN3B 

AMPA receptors

• GluRA = GluR1 = GluA1
• GluRB = GluR2 = GluA2
• GluRC = GluR3 = GluA3
• GluRD = GluR4 = GluA4 

Kainate Receptors 

• GluR5 = GLUK5 = GluK1
• GluR6 = GLUK6 = GluK2
• GluR7 = GLUK7 = GluK3
• KA1 = GLUK1 = GluK4
• KA2 = GLUK2 = GluK5 

Delta Receptors

• δ1 = GluD1
• δ2 = GluD2
