WebMetabotropic GABA B receptors are G protein–coupled receptors (GPCRs), which, on the other hand, elicit slow (hundreds of milliseconds) and sustained activity ( 4) by triggering signal transduction pathways with downstream effectors such as ion channels and adenylyl cyclases, mainly via G i/o proteins ( Fig. 1 ). WebThe ionotropic glutamate receptor has three major structural domains: a large amino-terminal extracellular domain (ATD), an extracellular ligand binding domain (LBD), and a transmembrane region consisting of two helical segments per subunit. Binding of glutamate causes the “clamshell”- like LBD to close, resulting in opening of the pore.
