Glutamate receptor 2 (UniProt P19491; also known as AMPA-selective glutamate receptor 2, GluA2, GluR-2, GluR-B, GluR-K2, GluR2, Glutamate receptor ionotropic, AMPA 2) is encoded by the Gria2 (also known as Glur2) gene (Gene ID 29627) in rat species. Glutamate receptors are synaptic receptors located primarily on the membranes of neuronal cells. These receptors play important roles in neural communication, memory formation, learning, and regulation by mediating glutamate-dependent postsynaptic excitation. Glutamate receptors are divided into two types, ionotropic glutamate receptors (iGluRs) and metabotropic glutamate receptors (mGluRs). iGluRs form ion channel pores upon glutamate binding, while mGluRs indirectly activate ion channels on the plasma membrane via G protein-coupled signaling cascade. Although all iGluRs and mGluRs bind glutamate, they do exhibit different binding activities toward chemical ligands, such as NMDA, kainate, AMPA, L-AP4, ACPD, L-QA, and such distinciton is used to divide these receptors further into subtypes. Glutamate receptor 2 is an AMPA type iGluR, GluR-1 is initially produced with an N-terminal signal peptide sequence (a.a. 1-24), the removal of which yields the mature receptor with 4 transmembrane helices (a.a. 544-564, 592-610, 617-637, 813-833), having a large N-terminal extracellular domain (a.a. 24-543), followed by two intracellular loops (a.a. 565-591, 611-616), one extracellular loop (a.a. 638-812) and a C-terminal cytoplasmic tail (a.a. 834-883).
