The Ca2+ permeation mechanism of the ryanodine receptor revealed by a multi-site ion model

Although the permeation mechanisms for K+ and Na+ channels have been extensively studied, the ion permeation mechanism through Ca2+ channels was largely unknown. Here the authors develop a multisite Ca2+ model that can be used in the framework of classical MD simulations to study Ca2+ in a quantitat...

Sumario:Although the permeation mechanisms for K+ and Na+ channels have been extensively studied, the ion permeation mechanism through Ca2+ channels was largely unknown. Here the authors develop a multisite Ca2+ model that can be used in the framework of classical MD simulations to study Ca2+ in a quantitative manner, and use it to investigate the ion permeation mechanism of the ryanodine receptor 1.
