General annotation (Comments)

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.
Subunit structure	Generally pentameric. There are five types of GABA(A) receptor chains: alpha, beta, gamma, delta, and rho.
Subcellular location	Cell junction › synapse › postsynaptic cell membrane; Multi-pass membrane protein. Cell membrane; Multi-pass membrane protein.
Sequence similarities	Belongs to the ligand-gated ionic channel (TC 1.A.9) family. [View classification]
