Phospho-Ser408/409 GABAA Receptor, β3 subunit Antibody

Affinity purified rabbit polyclonal antibody

     
  • WB - Phospho-Ser408/409 GABAA Receptor, β3 subunit Antibody AN1206
    Western blot of rat hippocampal lysate showing specific immunolabeling of the ~53k GABAA β3 protein phosphorylated at Ser408/409 (control). Immunolabeling is blocked by the phospho-peptide (peptide) used as antigen but not by the corresponding dephosphopeptide (not shown).

Background

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 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 GABAA-Rs sensitive to GABA. However, coexpression of a γ-subunit is required for benzodiazepine modulation. Phosphorylation of serine 408 and serine 409 within the β3 subunit have been shown to be critical for the functional modulation of β3 containing recombinant receptors (Brandon et al., 2000).
