Acetylcholine receptor inhibiting toxin (nAChR inhibitor)

Channel
Nicotinic acetylcholine receptors (nAChR) are postsynaptic membrane proteins that undergo an extensive conformational change upon binding to acetylcholine, leading to opening of an ion-conducting channel across the plasma membrane.

Nicotinic receptors, with a molecular mass of 290 kDa, are made up of five subunits, arranged symmetrically around a central pore. Each subunit comprises four transmembrane domains with both the N- and C-terminus located extracellularly.

In vertebrates, nicotinic receptors are broadly classified into two subtypes based on their primary sites of expression: muscle-type nicotinic receptors and neuronal-type nicotinic receptors.		 image
Figure 1: Schematic representation of the fetal muscle subtype nAChR (a) and the adult muscle subtype nAChR (b).

In the muscle-type receptors, found at the neuromuscular junction, receptors are either the embryonic form, composed of α1, β1, δ and γ subunits in a 2:1:1:1 ratio (Fig.1a), or the adult form composed of α1, β1, δ and ε subunits in a 2:1:1:1 ratio (Fig.1b). The neuronal subtypes are various homomeric or heteromeric combinations of twelve different nicotinic receptor subunits: α2 through α10 and β2 through β4. Examples of the neuronal subtypes include: (α4)3(β2)2, (α4)2(β2)3 and (α7)5. In both muscle-type and neuronal-type receptors the subunits are somewhat similar to one another, especially in the hydrophobic regions.

Nomenclature Different pharmacological families have been described in all taxonomic groups, except in snakes (reviewed in King et al., 2008):
α toxins target acetylcholine receptor.
ψ toxins are noncompetitive antagonists of acetylcholine receptors.
