Ionotropic receptor
Extracted from the Wikipedia article Ligand-gated ion channel.
Ligand-gated ion channels (LICs, LGIC), also commonly referred to as ionotropic receptors, are a group of transmembraneion-channel proteins which open to allow ions such as Na, K, Ca, and/or Cl to pass through the membrane in response to the binding of a chemical messenger (i.e. a ligand), such as a neurotransmitter.
