      DescriptionChemiSCREEN™ Human PK1 Prokineticin Receptor Membrane Preparation
      OverviewFull-length human GPR73 cDNA, encoding PK1
      Background InformationProkineticins, also known as endocrine gland vascular endothelial growth factors (EG-VEGF), are two ~10 kD secreted proteins originally described to mediate angiogenesis and gastrointestinal smooth muscle contraction (Li et al., 2001; LeCouter et al., 2003). Subsequently, prokineticins have been found to mediate central nervous system functions including circadian rhythms and olfactory bulb development (Cheng et al., 2002; Ng et al., 2005). Two Gq-coupled receptors, PK1 and PK2 (also known as GPR73a and GPR73b), mediate cellular responses to prokineticins (Lin et al., 2002). Chemicon's PK1 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 PK1 interactions and its ligands. The membrane preparations exhibit a Kd of 0.11 nM for [125I]-Mamba Intestinal Toxin-1 (MIT-1). With 0.2 nM [125I]-MIT-1, 2.5 µg/well and 5 µg/well PK1 Membrane Prep typically yield greater than 5-fold signal-to-background ratio.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: Q8TCW9 # Receptor for prokineticin 1. Exclusively coupled to the G(q) subclass of heteromeric G proteins. Activation leads to mobilization of calcium, stimulation of phosphoinositide turnover and activation of p44/p42 mitogen-activated protein kinase.
      SIZE: 393 amino acids; 44770 Da
      SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
      TISSUE SPECIFICITY: Expressed in the stomach, throughout the small intestine, colon, rectum, thyroid gland, pituitary gland, salivary gland, adrenal gland, testis, ovary, brain, spleen, prostate and pancreas.
      SIMILARITY: SwissProt: Q8TCW9 ## 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: [125I]-MIT-1 (Perkin Elmer#:NEX-410 )
      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 10-fold signal:background with 125I-labeled MIT-1 at 0.2 nM
