GABA A (γ-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 neuro- transmitter receptors in the CNS.
GABA A receptors are heteropentamer combinations of seven subunit types; alpha, beta, γ, δ, ε, θ, and π.
Three subunits, alpha, beta, and γ, have at least three separate gene products in mammals, and typical GABA A receptors have some combination of alpha, beta and γ subunits.
The rat γ2 isoform is a 48kD, 436aa, 4 transmembrane protein with two terminal extracellular regions.
The ligand-binding region is in the N-terminus aa30-233.
The γ 2 subunit is part of the most common GABAA receptor combination in the mammalian brain (alpha 1 beta 2γ2).
GABA binds at alpha-beta interfaces, while benzodiazepine binds to alpha-γ interfaces.
There are two splice forms, the longest contains a consensus phosphorylation site in the second cytoplasmic domain, and a short form that shows an absence of this site through a deletion of aa376-383.
PKC phosphorylates the long form at S381, while both the short and long forms are phos- phorylated at S365.
Phosphorylation blocks receptor activity.
The γ 2 subunits are also palmitoylated at multiple sites on cysteines that lay between aa415-461, facilitating membrane trafficking.
