描述 ChemiSCREEN™ Membrane Preparation Recombinant Human mGLU2 Metabotropic Glutamate Receptor 概述 human GRM2 cDNA encoding mGlu2 背景信息 Glutamate is a main excitatory neurotransmitter in the central nervous system, and it plays a role in learning, memory and neurotoxicity. The biological actions of glutamate are mediated by ionotropic and metabotropic glutamate receptors, which are ion channels and GPCRs respectively. Metabotropic glutamate receptors (mGluRs) are members of the class 3 G-protein coupled receptor family, which are characterized by a large extracellular domain. They are further classified into group I, II, and III mGluRs on the basis of their sequence identity, pharmacology, and signal transduction mechanism. Group I (mGlu1 and mGlu5) couple to the phospholipase C pathway through Gαq, whereas group II (mGlu2 and mGlu3) and group III (mGlu4, mGlu6, mGlu7, and mGlu8) negatively couple to the adenylyl cyclase pathway though Gαi (Conn and Pin, 1997). Agonists of the Group II metabotropic glutamate receptors, mGlu2 and mGlu3, display efficacy in animal models of anxiety and psychosis. A key role for mGlu2 in mediating these effects is indicated by the observation that selective allosteric potentiator of mGlu2 also retains antipsychotic-like activities in mice (Galici et al., 2005). In addition, mGlu2/3 agonists display analgesic activity in animal models (Jones et al., 2005). Chemicon's mGlu2 membrane preparations are crude membrane preparations made from our proprietary stable recombinant cell lines to ensure high-level of GPCR surface expression; thus, they are ideal HTS tools for screening of mGlu2 interactions with its ligands. The cell line exhibits a calcium response with EC50s of 0.51uM, 5.6uM, and 8.3uM for DCG IV, (2R4R) APDC, and glutamate. The membrane preparations exhibit EC50s of of 0.72uM, 5.07uM, and 6.29uM for DCG IV, (2R4R) APDC, and glutamate in a GTPγS binding assay. 产品信息 格式 Membranes 演示 Liquid in packaging buffer: 50 mM Tris pH 7.4, 10% glycerol and 1% BSA with no preservatives.
Packaging method: Membrane protein was adjusted to 1 mg/ml in packaging buffer, rapidly frozen, and stored at -80°C.应用 应用 Human mGlu2 GPCR membrane preparation for Radioligand binding Assays & GTPγS binding. 应用说明 Radioligand binding assay and GTPγS binding 生物信息 品种 Human Entrez基因编号 - NM_000839.2
Entrez基因汇总 L-glutamate is the major excitatory neurotransmitter in the central nervous system and activates both ionotropic and metabotropic glutamate receptors. Glutamatergic neurotransmission is involved in most aspects of normal brain function and can be perturbed in many neuropathologic conditions. The metabotropic glutamate receptors are a family of G protein-coupled receptors, that have been divided into 3 groups on the basis of sequence homology, putative signal transduction mechanisms, and pharmacologic properties. Group I includes GRM1 and GRM5 and these receptors have been shown to activate phospholipase C. Group II includes GRM2 and GRM3 while Group III includes GRM4, GRM6, GRM7 and GRM8. Group II and III receptors are linked to the inhibition of the cyclic AMP cascade but differ in their agonist selectivities. 基因符号 - GLUR2

GPCR类别 C 宿主细胞 Chem-1 蛋白靶 mGlu2 靶子系列 Glutamate (metabotropic) UniProt编号 - Q14416
UniProt汇总 FUNCTION: SwissProt: Q14416 # Receptor for glutamate. The activity of this receptor is mediated by a G-protein that inhibits adenylate cyclase activity. May mediate suppression of neurotransmission or may be involved in synaptogenesis or synaptic stabilization.
SIZE: 872 amino acids; 95568 Da
SUBUNIT: Interacts with GRASP (By similarity).
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
TISSUE SPECIFICITY: Widely expressed in different regions of the adult brain as well as in fetal brain.
SIMILARITY: SwissProt: Q14416 ## Belongs to the G-protein coupled receptor 3 family.孵化条件 Membranes are permeabilized by addition of saponin to an equal concentration by mass, then mixed with [35S]-GTPγS (final concentration of 0.1 nM) in 20 mM HEPES, pH 7.4/100 mM NaCl/10 mM MgCl2/0.5 µM GDP in a nonbinding 96-well plate. Unlabeled DCG IV, (2R4R) APDC, and glutamate are added to the final concentration indicated in Figure 1 (final volume 100 µL), and incubated for 30 min at 30°C. The binding reaction is transferred to a GF/B filter plate (Millipore MAHF B1H) previously prewetted with water, and washed 3 times (1 mL per well per wash) with cold 10 mM sodium phosphate, pH 7.4. The plate is dried and counted.
One vial contains enough membranes for at least 200 assays (units), where one unit is the amount of membrane that will yield greater than 1000 cpm specific DCG IV, (2R4R) APDC, or glutamate -stimulated [35S]-GTPγS binding.
The mGlu2 membrane preparation is expected to be functional in a radioligand binding assay; however, the end user will need to determine the optimal radiolabeled ligand for use with this product.产品使用声明 质量保证 EC50 in GTPγS binding assay by Glutamate: ~ 6.29 μM
