DescriptionChemiSCREEN™ Human δ Opioid Receptor Membrane Preparation
OverviewFull-length human OPRD1 cDNA encoding δ opioid receptor
Background InformationOpiates derived from the opium poppy, Papaver somniferum, have been used in for millenia for their anti-diarrheal, analgesic and euphoric properties. More recently, endogenous peptides, enkephalins, dynorphins, and endorphins, were found to bind to the same sites as opiate alkaloids. The receptors for the classical opioids are three related GPCRs, δ, κ, and μ (also known as OP1, OP2 and OP3, resepctively), that activate Gi/o to reduce intracellular cAMP levels. Although most clinically used opioids function by activation of the µ opioid receptor, agonits of spinal δ opioid receptors have antinociceptive activity that is independent of µ. In addition, activation of δ increases locomotor activity, inhibits gastrointestinal motility, and decreases respiratory frequency (Dhawan et al., 1996). Agonists for δ opioid receptors also exhibit antidepressant-like activity in animal models (Broom et al., 2002). Chemicon's δ 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 δ. The membrane preparations exhibit a Kd of 1.12 nM for [3H]-DADLE. With 0.9 nM [3H]-DADLE, 10 µg/well δ Membrane Prep typically yields greater than 4-fold signal-to-background ratio.

UniProt SummaryFUNCTION: SwissProt: P41143 # Inhibits neurotransmitter release by reducing calcium ion currents and increasing potassium ion conductance. Highly stereoselective. receptor for enkephalins.
SIZE: 372 amino acids; 40413 Da
SUBUNIT: Interacts with GPRASP1.
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
SIMILARITY: SwissProt: P41143 ## 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, an FC 96-well harvest plate (Millipore cat. # MAHF C1H) is coated with 0.33% polyethyleneimine for 30 min, then washed with 50mM Tris-HCl. 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 Tris-HCl, filtered and stored at 4°C
Radioligand: [3H] DADLE (Perkin Elmer#: NET-648)
Wash Buffer: 50 mM Tris-HCl, filtered and stored at 4°C.
