1. Voltage sensor activation and modulation in ion channels
Sammanfattning : Voltage-gated ion channels play fundamental roles in neural excitability, they are for instance responsible for every single heart beat in our bodies, and dysfunctional channels cause disease that can be even lethal. Understanding how the voltage sensor of these channels function is critical for drug design of compounds targeting neuronal excitability. LÄS MER
2. Dynamics of the voltage-sensor domain in voltage-gated ion channels : Studies on helical content and hydrophobic barriers within voltage-sensor domains
Sammanfattning : Voltage-gated ion channels play fundamental roles in neural excitability and thus dysfunctional channels can cause disease. Understanding how the voltage-sensor of these channels activate and inactivate could potentially be useful in future drug design of compounds targeting neuronal excitability. LÄS MER
3. Modeling of voltage-gated ion channels
Sammanfattning : 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. LÄS MER
4. Gating and modulation mechanism of voltage gated sodium channels
Sammanfattning : 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. LÄS MER
5. Membrane Induced Structure in Transmembrane Signaling Proteins and Peptides : Peptide–Lipid Interactions Studied by Spectroscopic Methods
Sammanfattning : Biological membranes, defining the boundary of cells and eukaryotic organelles, are mainly composed of lipids and membrane proteins. Interactions between these lipids and proteins are needed to preserve the tight seal of the membrane, but also to induce structure for proper function in many membrane proteins. LÄS MER
