描述 ChemiScreen™ Human V2 Vasopressin Receptor Membrane Preparation 概述 TRANSFECTION: Full-length human AVPR2 cDNA encoding V2 背景信息 Arginine vasopressin (AVP) is a 9 amino acid peptide that functions as an antidiuretic, vasoconstrictor and neurotransmitter. The three vasopressin receptors, V1a, V1b and V2, are GPCRs; V1a and V1b couple to Gq and calcium release, whereas V2 couples to Gs. V2 expressed in renal collecting ducts plays an important role in regulating renal free water excretion (Birnbaumer, 2000). Mutations in V2 result in X-linked nephrogenic diabetes insipidus, a syndrome in which the kidney is unable to concentrate urine, leading to dehydration and hypernatremia (Birnbaumer, 2001). Conversely, elevated levels of AVP lead to hyponatremia in the syndrome of inappropriate antidiuretic hormone secretion (SIADH), congestive heart failure or cirrhosis, and V2 selective antagonists have been developed to treat these conditions (Verbalis, 2002). Chemicon's V2 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 antagonists of V2 interactions and its ligands. The membrane preparations exhibit a Kd of 2.83 nM for [3H]-[Arg8] Vasopressin. With 3.5 nM [3H]-[Arg8] Vasopressin, 10 μg/well V2 Membrane Prep yields greater than 8-fold signal-to-background ratio. 产品信息 演示 Liquid in packaging buffer: 50 mM Tris pH 7.4, 10% glycerol and 1% BSA no preservatives.
Packaging method: Membranes protein were adjusted to 0.5 mg/ml in 1 ml packaging buffer, rapidly frozen, and stored at -80°C.应用 应用 Human V2 GPCR membrane preparation for Radioligand binding Assays & GTPγS binding. 应用说明 Radioligand binding assay and GTPγS binding. 生物信息 浓缩 4mL; 0.5 mg/mL 品种 Human Entrez基因编号 - NM_000054.2
Entrez基因汇总 This gene encodes the vasopressin receptor, type 2, also known as the V2 receptor, which belongs to the seven-transmembrane-domain G protein-coupled receptor (GPCR) superfamily, and couples to Gs thus stimulating adenylate cyclase. The subfamily that includes the V2 receptor, the V1a and V1b vasopressin receptors, the oxytocin receptor, and isotocin and mesotocin receptors in non-mammals, is well conserved, though several members signal via other G proteins. All bind similar cyclic nonapeptide hormones. The V2 receptor is expressed in the kidney tubule, predominantly in the distal convoluted tubule and collecting ducts, where its primary property is to respond to the pituitary hormone arginine vasopressin (AVP) by stimulating mechanisms that concentrate the urine and maintain water homeostasis in the organism. When the function of this gene is lost, the disease Nephrogenic Diabetes Insipidus (NDI) results. The V2 receptor is also expressed outside the kidney although its tissue localization is uncertain. When these 'extrarenal receptors' are stimulated by infusion of a V2 selective agonist (dDAVP), a variety of clotting factors are released into the bloodstream. The physiologic importance of this property is not known - its absence does not appear to be detrimental in NDI patients. The gene expression has also been described in fetal lung tissue and lung cancer associated with alternative splicing. 基因符号 - MGC138386

GPCR类别 A 宿主细胞 Chem-1 蛋白靶 V2 靶子系列 Vasopressin UniProt编号 - P30518
UniProt汇总 FUNCTION: SwissProt: P30518 # Receptor for arginine vasopressin. The activity of this receptor is mediated by G proteins which activate adenylate cyclase.
SIZE: 371 amino acids; 40279 Da
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
TISSUE SPECIFICITY: Kidney.
DISEASE: SwissProt: P30518 # Defects in AVPR2 are the cause of nephrogenic syndrome of inappropriate antidiuresis (NSIAD) [MIM:300539]. This disorder is characterized by an inability to excrete a free water load, with inappropriately concentrated urine and resultant hyponatremia, hypoosmolarity, and natriuresis. & Defects in AVPR2 are a cause of X-linked nephrogenic diabetes insipidus, type I (NDI) [MIM:304800]. It is characterized by excessive water drinking (polydypsia) and urine excretion (polyuria) and fail to concentrate urine in response to vasopressin. Most cases of NDI appear to have an X-linked recessive pattern of inheritance.
SIMILARITY: SwissProt: P30518 ## Belongs to the G-protein coupled receptor 1 family.孵化条件 Membranes are mixed with radioactive ligand and unlabeled competitor (see Figures 1 and 2 for concentrations tested) in binding buffer in a nonbinding 96-well plate, and incubated for 1-2 h. Prior to filtration, a GF/C 96-well filter plate is coated with 0.33% polyethyleneimine for 30 min, then washed with 50mM HEPES, pH 7.4, 0.5% BSA. Binding reaction is transferred to the filter plate, and washed 3 times (1 mL per well per wash) with Wash Buffer. The plate is dried and counted.
