potassium channel a voltage-gated protein channel selective for the passage of potassium ions. protein channel a watery pathway through the interstices of a protein molecule by which ions and small molecules can cross a membrane into or out of a cell by diffusion.
Voltage-gated sodium channels (Na v) are key components for nerve excitability. They initiate and propagate the action potential in excitable cells, throughout the central and peripheral nervous system, thus enabling a variety of physiological functions to be achieved.odium channels, other than epithelial Na + channels (ENaC) or sodium leak channels (NALCN), belong to the superfamily of voltage-gated ion channels, which all share the property of carrying ions between cellular compartments in response to membrane voltage stimulation (Stock et al., 2013).
