GABRB3 Antibody (Bi-Phospho-Ser408/409)

Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the central nervous system. There are two major classes of GABA receptors: the GABAA and the GABAB subtype of receptors. GABAA-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 sub-stance abuse. The GABAA-R is a multimeric subunit complex. To date six alpha s, four beta s and four gamma s, 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 alpha - and beta -subunits results in the expression of functional GABAA-Rs sensitive to GABA. However, coexpression of a gamma -subunit is required for benzodiazepine modulation. Phosphorylation of serine 408 and serine 409 within the beta 3 subunit have been shown to be critical for the functional modulation of beta 3 containing recombinant receptors (Brandon et al., 2000) .

Liquid.// 100 ul in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 ug per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.

For long term storage -80C is recommended, but shorter term storage at -20C is also acceptable as aliquots may be taken without freeze/thawing due the presence of 50% glycerol. Stock solution are stable for minimum of 1 year at -20C.

Specific for the ~53kD GABRB3 phosphorylated at Ser408/Ser 409. Immunolabeling of the GABAA band is completely blocked by the phospho-peptide used as antigen but not by the corresponding dephospho-peptide.
