      DescriptionChemiScreen™ D5 Dopamine Receptor Membrane Preparation
      OverviewFull-length human DRD5 cDNA encoding D5
      Background InformationDopamine is a catecholamine neurotransmitter that functions in the CNS to control locomotor, cognitive, emotional and neurendocrine processes, and in the periphery to modulate cardiovascular, renal and gastrointestinal processes. The biological activities of dopamine are mediated by a family of five GPCRs. The D1 and D5 subtypes couple to Gs to increase intracellular cAMP, whereas the D2, D3 and D4 subtypes couple to Gi to reduce cAMP (Missale et al., 1998). The hypertensive phenotype of mice with a targeted deletion of D5 indicates that D5 regulates central control of sympathetic vascular tone (Hollon et al., 2002). In addition, D5 modulates locomotion and corticostriatal long-term depression (Centonze et al., 2003). Chemicon's cloned human D5-expressing cell line is made in the Chem-1 host, which supports high levels of recombinant D5 expression on the cell surface and contains high levels of the promiscuous G protein Gα15 to couple the receptor to the calcium signaling pathway. Thus, the cell line is an ideal tool for screening for antagonists of interactions between D5 and its ligands. The membrane preparations exhibit a Kd of 2.25 nM for [3H]-SCH 23390. With 0.5 nM [3H]-SCH 23390, 10 µg/well D5 Membrane Prep yields greater than 3-fold signal-to-background ratio.

      Biological Information
      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes the D5 subtype of the dopamine receptor. The D5 subtype is a G-protein coupled receptor which stimulates adenylyl cyclase. This receptor is expressed in neurons in the limbic regions of the brain. It has a 10-fold higher affinity for dopamine than the D1 subtype. Pseudogenes related to this gene reside on chromosomes 1 and 2.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P21918 # 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: 477 amino acids; 52951 Da
      SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
      TISSUE SPECIFICITY: Neuron-specific, localized primarily within limbic regions of the brain.
      DISEASE: SwissProt: P21918 # Defects in DRD5 may be a cause of schizophrenia, but no proof has yet been found. & Defects in DRD5 are a cause of blepharospasm [MIM:606798]. It is a primary focal dystonia affecting the orbicularis oculi muscles, usually beginning in middle age. Initial symptoms include eye irritation and frequent blinking, progressing to involuntary spasms of eyelid closure. In severe cases, this can lead to functional blindness.
      SIMILARITY: SwissProt: P21918 ## 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]-SCH 23390. (Perkin Elmer#:NET-930 )
      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 3-fold signal:background with 3H labeled SCH 23390 at 0.5 nM
