Gene Information

General description

GABAA and GABAB receptors differ with regard to their ionic characteristics and pharmacological properties. The GABAA receptor is an ionotropic receptor that forms the GABA gated chloride channel and consists of several heterogeneous subunits with membrane recognition sites for benzodiazapenes. GABAA receptor is a ligand-gated chloride channel that is a multimeric subunit complex. So far, around 16 subunits have been identified. This gene encodes the β 2 subunit, which maps to human chromosome 5q34. It is present in a cluster along with genes encoding α 1 and γ 2 subunits of the GABAA receptor.

Immunogen

fusion protein of MBP with the amino acid sequence representing the cytosolic loop of the rat GABAA receptor (β2 subunit)

Application

Anti-GABAA Receptor (β2 subunit), cytosolic loop antibody produced in rabbit is suitable for western blotting at a working dilution of 1:1000-1:2000 using rat brain membrane. It is also suitable for immunoprecipitation.

Biochem/physiol Actions

The inhibitory neurotransmitter GABA signals through two distinct types of pre- and postsynaptic receptors, GABAA and GABAB. Both GABA receptors can regulate depression of synaptic transmission and be involved in the inhibition controlling neuronal excitability. Alterations in N-glycosylation of α1, β1, and β2 have been observed in schizophrenic patients.

The gamma-aminobutyric acid receptor (GABAAR) is a multisubunit Cl- channel that mediates most fast inhibitory synaptic transmission in the central nervous system. Molecular evolution has given rise to many genetic variants of GABAAR subunits, including alpha 1-6, beta 1-4, gamma

The molecular mechanisms of schizophrenia have been under investigation for decades; however, the exact causes of this debilitating neuropsychiatric disorder are still unknown. Previous studies have identified multiple affected neurotransmitter systems, brain regions, and cell types, each making a unique

Gamma-aminobutyric acid (GABA) acts on pharmacologically and functionally distinct receptors. These sites designated GABA-A and GABA-B receptors, differ with regard to their ionic characteristic and pharmacological properties. The most important distinction is, that the GABA-A receptor is associated with chloride

We demonstrated previously that an alpha 1-beta 2-gamma 2 gene cluster of the gamma-aminobutyric acid (GABAA) receptor is located on human chromosome 5q34-q35 and that an ancestral alpha-beta-gamma gene cluster probably spawned clusters on chromosomes 4, 5, and 15. Here
