Background: GABA-A R beta 1
GABAA ( gamma -aminobutyric acid-type A) receptors are members of the cysteine-loop family of neurotransmitter-gated ion channels. GABA binding to A-type receptors induces anion-selective ion channel opening. These receptors are the principal fast inhibitory neurotransmitter receptors in the CNS. GABAA receptors are heteropentamer combinations of seven subunit types; alpha, beta, gamma, δ, epsilon, theta, and π. Three subunits, alpha, beta, and gamma, have at least three separate gene products in mammals, and typical GABAA receptors have some combination of alpha, beta and gamma subunits. The rat beta 1 isoform is a 58 - 60 kDa, 449 amino acid (aa), 4 transmembrane protein with two terminal extracellular regions. The ligand-binding region is in the N-terminus (aa 13 - 218). The beta 1 subunit is known to be phosphorylated on a consensus phosphorylation site (S409 of the precursor) that exists in the cytoplasmic domain between transmembrane segments 3 and 4. PKA or PKC beta II-induced phosphorylation decreases GABAA receptor activity.
