  • potassium channel activity
  • delayed rectifier potassium channel activity
Processes
  • potassium ion transport
  • synaptic transmission
  • potassium ion transmembrane transport
  • protein homooligomerization
  • regulation of neurotransmitter secretion

General FunctionVoltage-gated potassium channel activity
Specific FunctionThis 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.
