Functions
  • voltage-gated sodium channel activity
Processes
  • neuronal action potential
  • muscle contraction
  • sodium ion transport
  • sodium ion transmembrane transport
  • membrane depolarization during action potential
Components
  • voltage-gated sodium channel complex
  • plasma membrane
  • integral component of plasma membrane
General FunctionVoltage-gated sodium channel activity
Specific FunctionThis protein mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient. This sodium channel may be present in both denervated and innervated skeletal muscle.
