The channels are found as ionotropic receptors or G-protein coupled receptors.
Two classes of glutamate receptors exist: ionotropic receptors (iGluRs), and metabotropic receptors (mGluRs).
GluR1, GluR2/3, GluR4, and GluR6/7 belong to the ionotropic receptors (iGluRs).
Three of these are ionotropic receptors where the binding of glutamate to the receptor causes an ion channel to open on the dendrite of the neuron.
Metabotropic receptors are both slower and longer acting than ionotropic receptors, for they activate a second messenger cascade system that can result in the opening of ion channels located elsewhere on the same postsynaptic membrane.
Urothelium also expresses a host of other metabotropic and ionotropic receptors such as TRPV1 and TRPM8, whose functional role is yet to be confirmed.
It has been shown that (--)-linalool modulates glutamate activation in vitro and in vivo by competitive antagonism of ionotropic receptors of the type N-methyl-D-aspartate (NMDA) (Elisabetsky and Silva Brum 2003; Silva Brum et al.
For example, the new study indicates that butylamine sensation requires a member of another family of unrelated molecular sensors known as Ionotropic Receptors (IRs) that have recently been described in the fruitfly Drosophila melanogaster.
Ionotropic receptors are ligand-gated channel receptors located directly at the synapse on the dendritic spines.

Among the three known classes of GABA receptors, GABAa and GABAc ionotropic receptors (ion channels), and GABAb metabotropic receptors (G protein-coupled receptors), the GABAa receptor is one of the most promising targets for a wide range of CNS-related diseases including anxiety, irritability, insomnia, and depression (Mohler et al.
