Functions
GABA-A receptor activity / transmembrane signaling receptor activity
Processes
chloride transmembrane transport / signal transduction
Components
chloride channel complex / GABA-A receptor complex / neuron projection / plasma membrane / postsynaptic membrane / receptor complex / synapse
General Function
Theta subunit of the heteropentameric ligand-gated chloride channel gated by gamma-aminobutyric acid (GABA), a major inhibitory neurotransmitter in the brain (PubMed:10449790, PubMed:16412217). 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 interfaces (By similarity). When activated by GABA, GABAARs selectively allow the flow of chloride anions across the cell membrane down their electrochemical gradient (PubMed:10449790, PubMed:16412217)
