ChemiScreen™ D1 Dopamine Receptor Membrane Preparation

Description:
ChemiScreen™ D1 Dopamine Receptor Membrane Preparation
Trade Name:
  • ChemiScreen
  • Chemicon (Millipore)
Qty/Pk:
200 assays
Product Overview:
Full-length human DRD1 cDNA
Background Information:
Dopamine exerts its action by binding to five distinct dopamine receptors, all of which belong to G protein-coupled receptor family (Missale et al. 1998). The D1 subtype is the most abundant dopamine receptor in the central nervous system. Activation of D1 receptor stimulates adenylyl cyclase, activates cyclic AMP-dependent protein kinases. It regulates neuronal growth and development, mediate some behavioral responses and modulate dopamine receptor D2-mediated events. Chemicon's D1 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 H1 interactions and its ligands. The membrane preparations exhibit a Kd of 1.5 nM for [3H]-SCH 23390. With 1.5 nM [3H]- SCH 23390, 2.5 µg/well and 10 µg/well D1 Membrane Prep typically yield greater than 5 and 15-fold signal-to-background ratios, respectively.
Applications:
Human D1 GPCR membrane preparation for Radioligand binding Assays & GTPgammaS binding.

Entrez Gene Summary:
This gene encodes the D1 subtype of the dopamine receptor. The D1 subtype is the most abundant dopamine receptor in the central nervous system. This G-protein coupled receptor stimulates adenylyl cyclase and activates cyclic AMP-dependent protein kinases. D1 receptors regulate neuronal growth and development, mediate some behavioral responses, and modulate dopamine receptor D2-mediated events. Alternate transcription initiation sites result in two transcript variants of this gene.
UniProt Summary:
FUNCTION: SwissProt: P21728 # This is one of the five types (D1 to D5) of receptors for dopamine. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase.
SIZE: 446 amino acids; 49293 Da
SUBUNIT: Interacts with DNAJC14 via its C-terminus (By similarity). Interacts with DRD1IP.
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein (By similarity). Endoplasmic reticulum membrane; Multi-pass membrane protein (By similarity). Note=Transport from the endoplasmic reticulum to the cell surface is regulated by interaction with DNAJC14 (By similarity).

Product Name:
ChemiScreen™ D1 Dopamine Receptor Membrane Preparation
Quality Assurance:
Bmax: 11.85 pmol/mg; Kd: 1.5 nM
Incubation Conditions:
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 Tris, pH 7.4, 10 mM MgCl2, 1 mM EDTA, filtered and stored at 4°C
Radioligand: [3H] SCH 23390 (Perkin Elmer#:NET-930 )
Wash Buffer: 50 mM Tris, pH 7.4 filtered and stored at 4°C.
One package contains enough membranes for at least 200 assays (units), where an unit is the amount of membrane that will yield greater than 10-fold signal:background with 3H-labeled SCH 23390 at 1.5 nM
