Voltage-gated Na+-channels are transmembrane proteins that are responsible for the fast depolarizing phase of the action potential in nerve and muscular cells. In humans, mutations in these channels cause a wide rang of cardiovascular and neurological diseases. This project will entail both experimental techniques (molecular biology, biochemistry, crystallography) and computational methods (Molecular dynamics simulations and bioinformatics) to investigate the structure/function relationships, especially the permeation and gating processes, for voltage-gated sodium channels.
