GO Classification
Functions
GABA-gated chloride ion channel activity / transmitter-gated monoatomic ion channel activity involved in regulation of postsynaptic membrane potential
Processes
inhibitory synapse assembly / regulation of postsynaptic membrane potential / synaptic transmission, GABAergic
Components
cerebellar Golgi cell to granule cell synapse / dendrite membrane / postsynapse / postsynaptic specialization membrane / transmembrane transporter complex
General Function
Alpha subunit of the heteropentameric ligand-gated chloride channel gated by gamma-aminobutyric acid (GABA), a major inhibitory neurotransmitter in the brain (PubMed:8632757). GABA-gated chloride channels, also named GABA(A) receptors (GABAAR), consist of five subunits arranged around a central pore and contain GABA active binding site(s) located at the alpha and beta subunit interface(s) (By similarity). When activated by GABA, GABAARs selectively allow the flow of chloride anions across the cell membrane down their electrochemical gradient (By similarity). Alpha-6/GABRA6 subunits are found at both synaptic and extrasynaptic sites (PubMed:8632757). Chloride influx into the postsynaptic neuron following GABAAR opening decreases the neuron ability to generate a new action potential, thereby reducing nerve transmission (By similarity). Extrasynaptic alpha-6-containing receptors contribute to the tonic GABAergic inhibition. Alpha-6 subunits are also present on glutamatergic synapses (By similarity)
