Abstract:
This unit describes protocols to aid investigators in determining the electrophysiological and pharmacological profile of heterologously expressed voltage or calcium-activated potassium channels belonging to the Kv1.x and SK/IK gene families. Protocols for data acquisition as well as analysis are provided.

01:26Voltage-gated Ion Channels
Voltage-gated ion channels are transmembrane proteins that open and close in response to changes in the membrane potential. They are present on the membranes of all electrically excitable cells such as neurons, heart, and muscle cells.
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...
