Theoretical and simulation studies on voltage-gated sodium channels

Abstract

Voltage-gated sodium (Nav) channels are indispensable membrane elements for the generation and propagation of electric signals in excitable cells. The successes in the crystallographic studies on prokaryotic Nav channels in recent years greatly promote the mechanistic investigation of these proteins and their eukaryotic counterparts. In this paper, we mainly review the progress in computational studies, especially the simulation studies, on these proteins in the past years.

The structural organization of VGCCs. Only the opposing two TDs are shown to facilitate visual recognition. The PD (purple) and VSDs (brown) are connected by a half helix (cyan) between TMs S4 and S5. The SF region within the PD is colored in red. Ligands can bind at both PD and VSDs, as shown by the black arrows

(D) Aligned amino acid sequences for the SF region in various prokaryotic Nav channels as well as eukaryotic Nav and Cav channels. The four structural units in the eukaryotic channels are labeled as I, II, III and IV, respectively
