Cysteine Loop Ligand-Gated Ion Channel Receptors

**Definition:** A subfamily of ligand-gated ion channel receptors that share a characteristic loop which is formed by a disulfide bond between two CYSTEINE residues. These receptors typically contain five subunits with the cysteine-loop occurring near an N-terminal extracellular domain.
