The neurotransmitter GABA (γ-aminobutyric acid) inhibits the activity of signal-receiving neurons by interacting with the GABAA receptor on these cells.1 There are two major types of GABA receptors: the ionotropic GABAA (GABAA R) and the metabotropic GABAB receptors.
GABAA R belongs to the ligand gated ion channel superfamily.1,2
It is a heteropentamer, with all of its five subunits contributing to the pore formation. To date, eight subunit isoforms were cloned: α, β, γ, δ, ε, π, θ, and ρ.1
The native GABAA receptor, in most cases, consists of 2α, 2β and 1γ subunit. Three γ subunits genes have been identified in mammals.
The binding of GABA to its GABAA receptor results in conformational changes that open a Cl- channel, producing an increase in membrane conductance, resulting in inhibition of neural activity.2,3
Recently, a genetic linkage between familial epilepsy syndrome and mutations in the γ2 subunit of the GABAA receptor have been demonstrated.4,5
Species reactivity key:
Anti-GABA(A) γ2 Receptor (extracellular) Antibody (#AGA-005) is a highly specific antibody directed against an epitope of rat GABRG2. The antibody can be used in western blot, immunohistochemistry, and immunocytochemistry applications. The antibody recognizes an extracellular epitope and is thus suited for live cell imaging. It has been designed to recognize GABA(A) γ2 from human, rat, and mouse samples.
