1. Modeling of voltage-gated ion channels
Abstract : The recent determination of several crystal structures of voltage-gated ion channels has catalyzed computational efforts of studying these remarkable molecular machines that are able to conduct ions across biological membranes at extremely high rates without compromising the ion selectivity. Starting from the open crystal structures, we have studied the gating mechanism of these channels by molecular modeling techniques. READ MORE

2. Gating and modulation mechanism of voltage gated sodium channels
Abstract : Voltage-gated sodium channels (Nav channels) play an essential role in nerve impulse conduction in excitable cells. Thus, these channels are involved in several neurological and muscular disorders. Understanding their mechanism of functioning is essential for designing drugs targeting them. READ MORE

4. New aspects of voltage-gated calcium channel regulation in pancreatic beta-cells - Relevance for insulin release and type 2 diabetes
Abstract : Voltage-gated Ca2+ channels are essential transducers of cellular signals in many electrically excitable cells. In the pancreatic beta-cell they mediate controlled Ca2+ influx, which is the final trigger for Ca2+ dependent release (exocytosis) of the blood glucose lowering hormone insulin. READ MORE

5. Molecular aspects on voltage-sensor movement
Abstract : Voltage-gated ion channels are fundamental for electrical signaling in living cells. They are composed of four subunits, each holding six transmembrane helices, S1-S6. Each subunit contains a voltage-sensor domain, S1-S4, and a pore domain, S5-S6. READ MORE
