Abstract
Although the biological function of ion channels associated with cells has been clarified, an atomic level understanding of these transmembrane proteins is still lacking. Molecular Dynamics (MD) simulations are a well suited tool to gain insight into the function of such proteins in their host environment. First, we give a brief introduction to the field of ion channels by describing the basic properties, structure, and function of an ion channel. We then present specific results for three a-helical bundles: the synthetic LS2 and LS3 channels, and a shortened sequence of the M2 channel protein associated with the influenza virus.
