描述 ChemiSCREEN™ Membrane Preparation Recombinant Human CCR4 Chemokine Receptor 概述 Full-length human CCR4 cDNA encoding CCR4 背景信息 CCR4 is a GPCR that is activated by chemokines TARC (thymus and activation regulated chemokine) and MDC (macrophage-derived chemokine) (Olsen and Ley, 2001). NK cells, Th2 cells, cutaneous memory T cells, macrophages and platelets express CCR4 and respond to TARC and MDC (Andrew et al., 2001; Inngjerdingen et al., 2000; Gear et al., 2001; Soler et al., 2003). CCR4-null mice display reduced airway hyperresponsiveness to fungal spores, lipopolysaccharide-induced endotoxic shock, and cardiac allograft rejection (Chvatchko et al., 2000; Schuh et al., 2002; Huser et al., 2005). In addition, antibody -mediated antagonism of MDC inhibits development of insulitis and diabetes in NOD mice (Kim et al., 2002). Chemicon's CCR4 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 agonists and antagonists at CCR4. The cell line exhibits a calcium response with EC50 of 3.31nM for TARC. The membrane preparations exhibit EC50 of 5.76 nM for TARC 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.

Entrez基因汇总 The protein encoded by this gene belongs to the G-protein-coupled receptor family . It is a receptor for the CC chemokine - MIP-1, RANTES, TARC and MCP-1. Chemokines are a group of small polypeptide, structurally related molecules that regulate cell trafficking of various types of leukocytes. The chemokines also play fundamental roles in the development, homeostasis, and function of the immune system, and they have effects on cells of the central nervous system as well as on endothelial cells involved in angiogenesis or angiostasis. 基因符号 - CC-CKR-4

GPCR类别 A 宿主细胞 Chem-1 蛋白靶 CCR4 靶子系列 Chemokine UniProt编号 - P51679
UniProt汇总 FUNCTION: SwissProt: P51679 # High affinity receptor for the C-C type chemokines CCL17/TARC and CCL22/MDC. The activity of this receptor is mediated by G(i) proteins which activate a phosphatidylinositol- calcium second messenger system. Can function as a chemoattractant homing receptor on circulating memory lymphocytes and as a coreceptor for some primary HIV-2 isolates. In the CNS, could mediate hippocampal-neuron survival.
SIZE: 360 amino acids; 41403 Da
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
TISSUE SPECIFICITY: Predominantly expressed in the thymus, in peripheral blood leukocytes, including T-cells, mostly CD4+ cells, and basophils, and in platelets; at lower levels, in the spleen and in monocytes. Detected also in macrophages, IL-2-activated natural killer cells and skin-homing memory T-cells, mostly the ones expressing the cutaneous lymphocyte antigen (CLA). Expressed in brain microvascular and coronary artery endothelial cells.
PTM: In natural killer cells, CCL22 binding induces phosphorylation on yet undefined Ser/Thr residues, most probably by beta-adrenergic receptor kinases 1 and 2.
SIMILARITY: SwissProt: P51679 ## Belongs to the G-protein coupled receptor 1 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 TARC is 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 to TARC-stimulated [35S]-GTPγS binding.
The CCR4 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 1 unit = 5 µg
