Abstract:
Transmembrane sodium-ion gradients provide energy that can be harnessed by 'secondary transporters' to drive the translocation of solute molecules into a cell. Decades of study have shown that such sodium-coupled transporters are involved in many physiological processes, making them targets for the treatment of numerous diseases. Within the past year, crystal structures of several sodium-coupled transporters from different families have been reported, showing a remarkable structural conservation between functionally unrelated transporters. These atomic-resolution structures are revealing the mechanism of the sodium-coupled transport of solutes across cellular membranes.

Voltage-gated Ion Channels
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several types of...
