A structure-based model that describes activation and inactivation of a sodium channel.
While the Hodgkin-Huxley formalism successfully describes sodium channel gating, the molecular origin of its nonlinear voltage dependence remains unclear. We developed a structure-based model of Nav1.4 representing the four voltage-sensing domains, the isoleucine-phenylalanine-methionine (IFM) motif and the S6 gate as...
