GO Classification	Functions delayed rectifier potassium channel activity voltage-gated potassium channel activity Processes regulation of neurotransmitter secretion synaptic transmission protein tetramerization potassium ion transmembrane transport protein homooligomerization Components dendrite membrane neuromuscular junction neuronal cell body membrane plasma membrane voltage-gated potassium channel complex integral component of membrane axon terminus axolemma
General Function	Voltage-gated potassium channel activity
Specific Function	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.
