DescriptionChemiSCREEN™ Human M3 Muscarinic Acetylcholine Receptor Membrane Preparation
OverviewFull-length human CHRM3 cDNA encoding M3
Background InformationThe muscarinic acetylcholine receptor (mAChR) family consists of five GPCRs that mediate some of the neurotransmission functions of acetylcholine in the CNS and the periphery. The M1, M3 and M5 receptors couple to Gq to mobilize intracellular calcium, whereas the M2 and M4 receptors couple to Gi/o to inhibit cAMP production (Caulfield and Birdsall, 1998). M3 is expressed prominently in smooth muscle, and plays a primary role in mediating mAChR agonist-induced contractility. Mice lacking M3 have dilated pupils, which indicates a role for M3 in regulating tone of the pupillary sphincter muscle. In addition, Msub3 plays a role in feeding, as indicated by the lean and hypophagic phenotype of M3-null mice (Wess, 2004). Chemicon's M3 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 M3 interactions with 4-DAMP. The membrane preparations exhibit a Kd of 0.72-1 nM for [3H]-4-DAMP. With 10 µg/well M3 Membrane Prep and 0.75 nM [3H]-4-DAMP, a greater than 4-fold signal-to-background ratio was obtained.

Biological Information
Entrez Gene Number
Entrez Gene SummaryThe 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 muscarinic cholinergic receptor 3 controls smooth muscle contraction and its stimulation causes secretion of glandular tissue.

UniProt Number
UniProt SummaryFUNCTION: SwissProt: P20309 # The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is Pi turnover.
SIZE: 590 amino acids; 66128 Da
SUBCELLULAR LOCATION: Basolateral cell membrane; Multi-pass membrane protein.
SIMILARITY: SwissProt: P20309 ## Belongs to the G-protein coupled receptor 1 family.
Incubation ConditionsMembranes 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]-4-DAMP (Perkin Elmer#:NET1040 )
Wash Buffer: 50 mM Hepes, pH 7.4, 500mM NaCl , 0.1% BSA, filtered and stored at 4°C.
One package contains enough membranes for at least 200 assays (units), where a unit is the amount of membrane that will yield greater than 4-fold signal:background with 3H labeled 4-DAMP at 0.75 nM
