Functions
  • transmitter-gated ion channel activity
  • glycine binding
  • extracellular-glycine-gated chloride channel activity
Processes
  • synaptic transmission, glycinergic
  • neuropeptide signaling pathway
  • transmembrane transport
  • ion transmembrane transport
  • chloride transmembrane transport
  • response to amino acid
  • regulation of membrane potential
  • neurological system process

General FunctionTransmitter-gated ion channel activity
Specific FunctionThe glycine receptor is a neurotransmitter-gated ion channel. Binding of glycine to its receptor increases the chloride conductance and thus produces hyperpolarization (inhibition of neuronal firing).
