Potassium channels are a diverse and widespread family of channels.
Simulation and modelling studies based on the KcsA structure are being used to address a number of aspects of the atomic resolution physiology of this and related K channels. Indira H. Shrivastava - Simulation Studies of Permeation and Selectivity of KcsA Figure 1. KCsA in a POPC Bilayer. Phil C. Biggin - Selectivity in Potassium Channels. The simulations comprised of placing each ion at various sampling positions along the length of the pore.
