Our Anti-GABAA Receptor γ2 (Ser327) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects mouse and rat GABAA Receptor γ2 (Ser327) and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of rat cortical lysate showing specific immunolabeling of the ~45 kDa GABAA γ2 protein phosphorylated at Ser327 in the first lane (-). Phosphospecificity is shown in the second lane (+) where immunolabeling is blocked by preadsorption of the phosphopeptide used as the antigen, but not by the corresponding non-phosphopeptide (not shown).
Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the central nervous system. There are two major classes of GABA receptors: the GABA-A and the GABA-AB subtype of receptors. GABA-A-Rs are important therapeutic targets for a range of sedative, anxiolytic, and hypnotic agents and are implicated in several diseases including epilepsy, anxiety, depression, and substance abuse. The GABA-A-R is a multimeric subunit complex. To date six αs, four βs and four γs, plus alternative splicing variants of some of these subunits, have been identified (Olsen and Tobin, 1990; Whiting et al., 1999; Ogris et al., 2004). Injection in oocytes or mammalian cell lines of cRNA coding for α- and β-subunits results in the expression of functional GABA-A-Rs sensitive to GABA. However, coexpression of a γ-subunit is required for benzodiazepine modulation. It has recently been suggested that PKCε regulates the sensitivity of GABA-A α1β2γ2 receptors to ethanol and benzodiazepines through phosphorylation of serine 327 in the large intracellular loop of γ2 (Qi et al., 2007)
