      ApplicationAnti-GABA B Receptor R2 Antibody detects level of GABA B Receptor R2 & has been published & validated for use in IH.
      Key Applications
      • Immunohistochemistry
      Application NotesImmunohistochemistry: 1:1,000-1:2,000 using a cyanine conjugated secondary antibody. Light 4% PFA fixation recommended. Permeabilization with 0.1-.2% triton in the block only; enzymatic detection can be used however substantially higher primary antibody dilutions will be necessary. Traditional formalin fixation is not recommended.

      Optimal working dilutions must be determined by the end user.
      Biological Information
      ImmunogenSynthetic peptide corresponding to the C-terminal amino acids of the rat and human GABAB-R2 receptor protein (Kaupman et al., 1998; White et al., 1998; Jones et al., 1998; Martin et al., 1999).
      ConcentrationPlease refer to the Certificate of Analysis for the lot-specific concentration.
      HostGuinea Pig
      SpecificityRecognizes GABAB-R2 receptor. The antiserum stains nerve fibers and cell bodies in untreated animals. The staining pattern for the immunoreactive cell bodies obtained with the GABAB-R2 receptor antiserum corresponds to the pattern described using in situ hybridization with probes to rat GABAB-R2 receptor mRNA (Durkin et al., 1999). Strong GABAB-R2 receptor immunoreactivity is e.g. demonstrated in the Purkinje cells of the cerebellum, in the cerebral cortex, in the medial habelulae, in the spinal cord and in the brainstem. In individual Purkinje neurons, the immunoreactivity is preferentially observed in the periphery of the cells, most likely corresponding to the plasma membrane, but also in the entire dendritic tree extending into the molecular cell layer of the cerebellum.

      Entrez Gene Number
      Entrez Gene SummaryB-type receptors for the neurotransmitter GABA (gamma-aminobutyric acid) inhibit neuronal activity through G protein-coupled second-messenger systems, which regulate the release of neurotransmitters and the activity of ion channels and adenylyl cyclase. See GABBR1 (MIM 603540) for additional background information on GABA-B receptors.[supplied by OMIM]

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: O75899 # Receptor for GABA. The activity of this receptor is mediated by G-proteins that inhibit adenylyl cyclase activity, stimulates phospholipase A2, activates potassium channels, inactivates voltage-dependent calcium-channels and modulates inositol phospholipids hydrolysis. Plays a critical role in the fine-tuning of inhibitory synaptic transmission. Pre-synaptic GABA-B-R inhibit neurotransmitter release by down-regulating high- voltage activated calcium channels, whereas postsynaptic GABA-B-R decrease neuronal excitability by activating a prominent inwardly rectifying potassium (Kir) conductance that underlies the late inhibitory postsynaptic potentials. Not only implicated in synaptic inhibition but also in hippocampal long-term potentiation, slow wave sleep, muscle relaxation and antinociception.
      SIZE: 941 amino acids; 105821 Da
      SUBUNIT: Heterodimer of GABA-B-R1 and GABA-B-R2. Neither of which is effective on its own and homodimeric assembly does not seem to happen. Interacts with ATF4 via its C-terminal region.
      SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. Note=Moreover coexpression of GABA-B-R1 and GABA-B-R2 appears to be a prerequisite for maturation and transport of GABA-B-R1 to the plasma membrane.
      TISSUE SPECIFICITY: Highly expressed in brain, especially in cerebral cortex, thalamus, hippocampus, frontal, occipital and temporal lobe, occipital pole and cerebellum, followed by corpus callosum, caudate nucleus, spinal cord, amygdala and medulla. Weakly expressed in heart, testis and skeletal muscle.
      DOMAIN: SwissProt: O75899 Alpha-helical parts of the C-terminal intracellular region mediate heterodimeric interaction with GABA-B receptor 1.
      SIMILARITY: Belongs to the G-protein coupled receptor 3 family. GABA-B receptor subfamily.
