Our mouse GABA-A-R-Beta2/3 monoclonal antibody from NeuroMab is produced in-house from clone 62-3G1. It detects bovine, chicken, human, mouse, and rat GABA-A-R-Beta2/3 and is purified by Protein A chromatography. Works in WB, IHC, ICC, IP, ELISA, EM.
GABA A receptors are members of the Cys-loop family of ligand-gated ion channels. GABA AR-beta2/3 a is a subunit of the pentameric GABA receptors where GABA is the major inhibitory neurotransmitter in the vertebrate brain and mediates neuronal inhibition by binding to the GABA receptor and opening an integral chloride channel. GABA AR beta2/3 has been found to be expressed in brain at the cell junction, synapse, postsynaptic cell membrane and cytoplasmic vesicle membrane.

Fraction of bovine brain GABA-A receptor affinity purified against immobilized benzodiazepine Ro7-1986/1 (1988 de Blas et al J Neurosci PMID 2828565, 1988 Vitorica et al J Neurosci PMID 2828566). Target initially identified as a GABA-A receptor by: 1). rat brain immunocytochemistry staining pattern via light microscopy identical to that seen via ligand autoradiography with 3H-muscimol; 2). immunoprecipitation of 3H-muscimol-binding activity of the purified receptor complex; 3). recognition of ~57 kDa protein in immunoblots against crude rat brain membrane fractions Binding epitope identified to be within amino acids 26-40 (QSVNDPGNMSFVKET, extracellular N-terminus, 1992 Ewert et al Brain Res, PMID 1377081) of human GABA-A-R-Beta3 (also known as Gamma-aminobutyric acid receptor subunit beta-3, accession number P28472)

UniProt Summary: Beta subunit of the heteropentameric ligand-gated chloride channel gated by gamma-aminobutyric acid (GABA), a major inhibitory neurotransmitter in the brain. GABA-gated chloride channels, also named GABA(A) receptors (GABAAR), consist of five subunits arranged around a central pore and contain GABA active binding site(s) located at the alpha and beta subunit interface(s). GABAARs containing beta-3/GABRB3 subunit are found at both synaptic and extrasynaptic sites. When activated by GABA, GABAARs selectively allow the flow of chloride anions across the cell membrane down their electrochemical gradient. Chloride influx into the postsynaptic neuron following GABAAR opening decreases the neuron ability to generate a new action potential, thereby reducing nerve transmission. GABAARs containing alpha-1 and beta-3 subunits exhibit synaptogenic activity; the gamma-2 subunit being necessary but not sufficient to induce rapid synaptic contacts formation. Extrasynaptic beta-3 receptors contribute to the tonic GABAergic inhibition. GABAARs containing alpha-1, beta-3 and epsilon subunits may also permit spontaneous chloride channel activity while preserving the structural information required for GABA-gated openings. Beta-containing GABAARs can simultaneously bind GABA and histamine where histamine binds at the interface of two neighboring beta subunits, which may be involved in the regulation of sleep and wakefulness. Plays an important role in somatosensation and in the production of antinociception.
