We present a framework for computing the gating properties of ligand-gated ion channel mutants using the Monod-Wyman-Changeux (MWC) model of allostery. We derive simple analytic formulas for key functional properties such as the leakiness, dynamic range, half-maximal effective concentration ([EC50]), and effective Hill coefficient, and explore
major pharmacological targets into which the Guide is divided, with the others being: G protein-coupled receptors, voltage-gated ion channels, other ion channels, nuclear hormone receptors, catalytic receptors, enzymes and transporters.

Gated ion channels are made up of multiple transmembrane proteins that create a pore, or channel, in the cell membrane. Depending upon its type, each ion channel is specific to the passage of a particular ionic species. The term “gated” refers to the fact that the ion channel is controlled by a “gate” which must be opened to allow the ions through. The gates are opened by the binding of an
Synthetic strategies for manipulating ligand-gated ion channels with light. ( a ) In the example of the ionotropic glutamate receptor GluK2, glutamate binding in the extracellular ligand binding domain triggers domain closure and gate opening.
Ligand-gated Ion Channels The nomenclature of ligand-gated ion channels and their subunits has recently been re-examined by NC-IUPHAR. Their revised recommendations for nomenclature are summarised here .
Ligand‐gated ion channels (LGICs) are integral membrane proteins that contain a pore which allows the regulated flow of selected ions across the plasma membrane. Ion flux is passive and driven by the electrochemical gradient for the permeant ions. The channels are opened, or gated, by the binding of a neurotransmitter to an orthosteric site(s) that triggers a conformational change that
Abstract. The Cys-loop receptors constitute an important superfamily of LGICs (ligand-gated ion channels) comprising receptors for acetylcholine, 5-HT 3 (5-hydroxytryptamine; 5-HT 3 receptors), glycine and GABA (γ-aminobutyric acid; GABA A receptors).
The three main conformational states of voltage-gated ion channels. From a closed state at the hyperpolarized resting From a closed state at the hyperpolarized resting membrane potential, channels open upon depolarization during an action potential via outward movement of the voltage sensors that

Ligand-gated Ion Channels (LGICs) are a group of transmembrane ion channels that open when a signal molecule (ligand) binds to an extracellular receptor region of the channel protein. This binding changes the structural arrangements of the channel protein, which then causes the channels to open or
In the case of the superfamily of nicotinic-receptor channels (also referred to as pentameric ligand-gated ion channels [pLGICs]), for example, two different types of model of the open-channel conformation have been proposed on the basis of structures solved to resolutions better than 4.0 Å.
In contrast to ligand-gated ion channels, there are also receptor systems in which the receptor and the ion channel are separate proteins in the cell membrane, instead of a single molecule. In this case, ion channels are indirectly modulated by activation of the receptor, instead of being gated directly.

Abstract. The Cys-loop receptors constitute an important superfamily of LGICs (ligand-gated ion channels) comprising receptors for acetylcholine, 5-HT 3 (5-hydroxytryptamine; 5-HT 3 receptors), glycine and GABA (γ-aminobutyric acid; GABA A receptors).
responses in the receptor cell: Receptors that act as ligand-gated ion channels result in rapid but short-lived responses, whereas receptors coupled to second-messenger systems induce slower but more prolonged responses. Ligand-Gated Channel Receptors.When a neurotransmit-ter molecule binds to a receptor that acts as a ligand-gated ion channel, a channel opens, allowing ions to flow across the

Gated ion channels are made up of multiple transmembrane proteins that create a pore, or channel, in the cell membrane. Depending upon its type, each ion channel is specific to the passage of a particular ionic species. The term “gated” refers to the fact that the ion channel is controlled by a “gate” which must be opened to allow the ions through. The gates are opened by the binding of an

Ligand‐gated ion channels (LGICs) are integral membrane proteins that contain a pore which allows the regulated flow of selected ions across the plasma membrane. Ion flux is passive and driven by the electrochemical gradient for the permeant ions. The channels are opened, or gated, by the binding of a neurotransmitter to an orthosteric site(s) that triggers a conformational change that

Background. Members of the cys-loop ligand-gated ion channel (cys-loop LGIC) superfamily mediate chemical neurotransmission and are studied extensively as potential targets of drugs used to treat neurological disorders such as Alzheimer’s disease.
