Structure of a class C GPCR metabotropic glutamate receptor 1 bound to an allosteric modulator
Completing the Set G protein–coupled receptors (GPCRs) are membrane proteins that transduce extracellular signals to activate diverse signaling pathways. Significant insight into GPCR function has come from structures of three of four classes of GPCRs—A,

AMPA and Kainate Receptors Each Mediate Excitotoxicity in Oligodendroglial Cultures
Recent studies indicate that oligodendrocytes are vulnerable to excitotoxic insults mediated by glutamate receptors. The present study was carried out to characterize the type of glutamate receptors triggering cell death in optic nerve oligodendrocyte ...

Glutamate receptors in the kidney [PDF]
l-Glutamate (l-Glu) plays an essential role in the central nervous system (CNS) as an excitatory neurotransmitter, and exerts its effects by acting on a large number of ionotropic and metabotropic receptors. These receptors are also expressed in several peripheral tissues, including the kidney.

Here, the authors use smFRET to assess the structural dynamics of metabotropic glutamate receptor mGlu2 and show that a positive allosteric modulator or the Gi protein stabilize mGlu2 in the glutamate-induced active state, leading to the full activation ...

Possible Role of N-Methyl-D-Aspartate Glutamate Receptors in The Induction of Acrosome Reaction in Human Sperm [PDF]
Objective: Acrosome reaction is a receptor and Ca2+-dependent process. N-Methyl-D- aspartate (NMDA) glutamatereceptors are expressed in the human sperm and are involved in the Ca2+ influx.

Glutamate triggers long-distance, calcium-based plant defense signaling
Rapid, long-distance signaling in plants A plant injured on one leaf by a nibbling insect can alert its other leaves to begin anticipatory defense responses. Working in the model plant Arabidopsis, Toyota et al. show that this systemic signal begins with

Structural mechanism of glutamate receptor activation and desensitization
Ionotropic glutamate receptors are ligand-gated ion channels that mediate excitatory synaptic transmission in the vertebrate brain. To gain a better understanding of how structural changes gate ion flux across the membrane, we trapped rat AMPA (α-amino-3-

Glutamate delta (GluD) receptors belong to the ionotropic glutamate receptor family, yet they don’t bind glutamate and are considered orphan. Progress in defining the ion channel function of GluDs in neurons has been hindered by a lack of pharmacological

Glutamate may be an efferent transmitter that elicits inhibition in mouse taste buds. [PDF]
Recent studies suggest that l-glutamate may be an efferent transmitter released from axons innervating taste buds. In this report, we determined the types of ionotropic synaptic glutamate receptors present on taste cells and that underlie this postulated
