Phospho-Ser783 GABAB R2 Antibody

Affinity purified rabbit polyclonal antibody

     
  • WB - Phospho-Ser783 GABAB R2 Antibody AN1125
    Western blot of rat synaptic membrane showing specific immunolabeling of the~102 k GABAB R2 protein phosphorylated at Ser783 (control). The phosphospecificity of this labeling is shown in the second lane (lambda-phosphatase: λ-Ptase). Theblot is identical to the control except that it was incubated in λ-Ptase (1200 unitsfor 30 min) before being exposed to the phospho-Ser783 GABAB antibody. The immunolabeling is completely eliminated by treatment with λ-Ptase.

Target/Specificity Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser783 conjugated to KLH.
Dilution WB~~ 1:1000
Format Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephospho-peptide affinity columns.
Antibody Specificity Specific for ~102k GABAB R2 phosphorylated at Ser783. Immunolabeling of the GABAB R2 band is completely blocked by λ-phosphatase treatment.

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. GABAB receptors are heterodimeric G protein-coupled receptors that mediate slow synaptic inhibition in the central nervous system. It has recently been demonstrated that AMPK binds directly to GABAB receptors and phosphorylates S783 in the cytoplasmic tail of the R2 subunit and that S783 plays a critical role in enhancing neuronal survival after ischemia as phosphorylation of S783 is evident in many brain regions and is increased dramatically after ischemic injury to the brain (Kuramoto et al., 2007).
