摘要：{gamma} -Aminobutyric acid type A (GABA-A) receptors are a major mediator of inhibitory neurotransmission in the mammalian central nervous system, and the site of action of a number of clinically important drugs. These receptors exist as a family of subtypes with distinct temporal and spatial patterns of expression and distinct properties that presumably underlie a precise role for each subtype. The newest member of this gene family is the {theta} subunit. The deduced polypeptide sequence is 627 amino acids long and has highest sequence identity (50.5%) with the {beta}1 subunit. Within the rat striatum, this subunit coassembles with 2, {beta}1, and {gamma}1, suggesting that {gamma}-aminobutyric acid type A receptors consisting of arrangements other than {beta} + {gamma
