G protein-coupled receptors (GPCRs) are the largest family of membrane receptors in humans and play a role in nearly all physiological processes. Among GPCRs, metabotropic glutamate receptors (mGluRs) are a structurally distinct family of synaptic receptors that are essential in regulating neurotransmission and synaptic plasticity. Due to their important regulatory...
Transfer of information across membranes is fundamental to the function of all organisms and is primarily initiated by transmembrane receptors. This is an allosteric process and involves conformational coupling between ligand-binding domain and signaling domain of a receptor. This allosteric mechanism of activation is unclear for many receptors. Moreover, for...
