Kv channel S6 helix as a molecular switch: simulation studies
Ion channels form pores of nanoscopic dimensions in biological membranes and play a key role in the physiology of cells. The majority of ion channels are gated, i.e. they contain a molecular switch that allows a transition between a closed (functionally 'off') and open (functionally 'on') state. Comparison of crystal structures of potassium channels suggest that the gating mechanism of voltage-gated potassium (Kv) channels involves a key role for the pore-lining S6 helix. There is a conserved...[Show more]
