GO Classification
Functions
chloride channel activity / GABA-A receptor activity / inhibitory extracellular ligand-gated ion channel activity
Processes
cellular response to histamine / chloride transmembrane transport / cochlea development / gamma-aminobutyric acid signaling pathway / inner ear receptor cell development / innervation / ion transmembrane transport / negative regulation of neuron apoptotic process / neurological system process / regulation of membrane potential / sensory perception of sound / synaptic transmission / synaptic transmission, GABAergic / transmembrane transport / transport
Components
cell junction / chloride channel complex / cytosol / extracellular exosome / GABA-A receptor complex / integral component of plasma membrane / neuron projection / plasma membrane / postsynaptic membrane / synapse
General Function
Inhibitory extracellular ligand-gated ion channel activity
Specific Function
Component of the heteropentameric receptor for GABA, the major inhibitory neurotransmitter in the vertebrate brain. Functions also as histamine receptor and mediates cellular responses to histamine. Functions as receptor for diazepines and various anesthetics, such as pentobarbital; these are bound at a separate allosteric effector binding site. Functions as ligand-gated chloride channel.
