Potassium voltage-gated channel subfamily C member 4

UniProtKB accession:  Q03721

Grouped By:  Matching UniProtKB accession

UniProtKB description:  This protein mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient.
