Recombinant Human M5 Muscarinic Acetylcholine Receptor概述 Full-length human CHRM5 cDNA, encoding M5 背景信息 The muscarinic acetylcholine receptor family consists of five GPCRs that mediate some of the neurotransmission functions of acetylcholine in the CNS and the periphery. The M5 receptor, along with the M1 and M3 receptors, signal through Gq/11 and subsequent release of Ca++ from the ER (Caulfield and Birdsall, 1998). Although M5 is expressed in the CNS at relatively low levels, it appears to be the only muscarinic acetylcholine receptor expressed in midbrain dopaminergic neurons, and it has been shown to mediate dopamine release from these neurons. The M5 receptor is also expressed in blood vessels in the brain and the periphery, and studies with M5 knockout mice demonstrate that M5 mediates the vasodilatory action of acetylcholine on cerebral microvessels. Further studies with M5 knockout mice also indicate a role for M5 in the rewarding effects of cocaine and morphine (Wess, 2004). Chemicon's M5 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 M5 interactions with its ligands. The membrane preparations exhibit a Kd of 0.16 nM for [3H]-Scopolamine methyl chloride (NMS). With 10 μg/well M5 Membrane Prep and 1 nM [3H]-NMS, greater than 5-fold signal-to-background ratio was obtained. 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 M5 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 品种反应性 Human Entrez基因编号 - NM_012125.2
Entrez基因汇总 The muscarinic cholinergic receptors belong to a larger family of G protein-coupled receptors. The functional diversity of these receptors is defined by the binding of acetylcholine and includes cellular responses such as adenylate cyclase inhibition, phosphoinositide degeneration, and potassium channel mediation. Muscarinic receptors influence many effects of acetylcholine in the central and peripheral nervous system. The clinical implications of this receptor are unknown; however, stimulation of this receptor is known to increase cyclic AMP levels. 基因符号 - HM5

SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
SIMILARITY: SwissProt: P08912 ## 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. Binding buffer: 50 mM Hepes, pH 7.4, 5 mM MgCl2, 1 mM CaCl2, 0.2% BSA, filtered and stored at 4°C Radioligand: [3H] NMS (Perkin Elmer#:NEX-636 )
Wash Buffer: 50 mM Hepes, pH 7.4, 500 mM NaCl , 0.1% BSA, filtered and stored at 4°C.
