It acts via two classes of receptors, ligand gated ion channels (ionotropic receptors) and G-protein coupled (metabotropic) receptors. Ionotropic glutamate receptors (iGluRs) are heteromeric ligand-gated ion channels. Based on their pharmacological and electrophysiological properties, iGluRs can be subdivided into three families: AMPA (α-amino-3-hydroxymethyl-4-isoxazolepropionic acid) receptor; NMDA (N-methyl-D-aspartate) receptor and KA (kinate) receptor. On the right is a closed channel (PDB entry 4tnv ). A leucine amino acid forms a tight ring at the center of the channel that blocks passage of ions. On the left is a channel with glutamate and ivermectin bound, which has opened the channel, allowing ions to pass (PDB entry 3rif ).

The mammalian ionotropic glutamate receptor family encodes 18 gene products that coassemble to form ligand-gated ion channels containing an agonist recognition site, a transmembrane ion …

NMDA, AMPA and Kainate receptors are members of the ionotropic class of glutamate receptors. This heterogeneous group of ion channels exist as cation-selective tetramers formed by homo- and hetero-oligomeric assembly of subunits. Abstract. The mammalian ionotropic glutamate receptor family encodes 18 gene products that coassemble to form ligand-gated ion channels containing an agonist recognition site, a transmembrane ion permeation pathway, and gating elements that couple agonist-induced conformational changes to the opening or closing of the permeation pore.

Five of these ion channel receptor families have been shown to form a sequence-related superfamily: * Nicotinic acetylcholine receptor (AchR), an excitatory cation channel in vertebrates and invertebrates; in vertebrate motor endplates it is composed of alpha, beta, gamma and delta/epsilon subunits; in neurons it is composed of alpha and non-alpha (or beta) subunits
