Function

[GRIK1_RAT] Ionotropic glutamate receptor. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. Binding of the excitatory neurotransmitter L-glutamate induces a conformation change, leading to the opening of the cation channel, and thereby converts the chemical signal to an electrical impulse. The receptor then desensitizes rapidly and enters a transient inactive state, characterized by the presence of bound agonist. May be involved in the transmission of light information from the retina to the hypothalamus.^[1]

Publication Abstract from PubMed

The X-ray structure of the ligand-binding core of the kainate receptor GluR5 (GluR5-S1S2) in complex with (S)-glutamate was determined to 1.95 A resolution. The overall GluR5-S1S2 structure comprises two domains and is similar to the related AMPA receptor GluR2-S1S2J. (S)-glutamate binds as in GluR2-S1S2J. Distinct features are observed for Ser741, which stabilizes a highly coordinated network of water molecules and forms an interdomain bridge. The GluR5 complex exhibits a high degree of domain closure (26 degrees) relative to apo GluR2-S1S2J. In addition, GluR5-S1S2 forms a novel dimer interface with a different arrangement of the two protomers compared to GluR2-S1S2J.
