Binding to muscarinic m3 receptors

WebThe crossing of this aromatic cage has been proposed as the rate-limiting step of M3 unbinding, suggesting that the M3 receptor should follow a two-state model binding kinetics in which the ligand adopts either a receptor-bound or a receptor-unbound state, with a predominant energy barrier separating these two free-energy minima.
