Abstract:
In this chapter we introduce the reader to the structures of the different types of ligand-gated ion-channel receptor, and the numerous receptor subtypes that have recently been revealed to exist, in both invertebrate and vertebrate species, by the application of molecular biological methods. We then review some of the data in support of the existence, in molluscs, of such receptor/channel complexes for gamma-aminobutyric acid, glutamate and acetylcholine. Finally, recent results from our laboratory on the cloning and expression of complementary DNAs, from the pond-snail Lymnaea stagnalis, that encode GABA(A) and glutamate receptor subunits will be described.

Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that include the...
