Electrically silent mutants unravel the mechanism of binding-gating coupling in Cys-loop receptors.

Abstract excerpt

The transduction of extracellular chemical signals into intracellular events relies on the communication between neighboring domains of membrane receptors. In the particular case of Cys-loop receptor channels, five short stretches of amino acids, one per subunit, link the extracellular and transmembrane domains in such a way that the ion permeability of the latter and the affinity for neurotransmitters of the...
