GO Classification
Functions
benzodiazepine receptor activity / chloride channel activity / GABA-A receptor activity / inhibitory extracellular ligand-gated ion channel activity
Processes
chloride transmembrane transport / gamma-aminobutyric acid signaling pathway / ion transmembrane transport / neurological system process / neurotransmitter transport / regulation of membrane potential / regulation of neurotransmitter levels / response to drug / synaptic transmission / transmembrane transport
Components
axon / cell junction / chloride channel complex / GABA-A receptor complex / integral component of plasma membrane / integral component of synaptic vesicle membrane / neuron projection / plasma membrane / postsynaptic membrane
General Function
Inhibitory extracellular ligand-gated ion channel activity
Specific Function
GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel.
