  • Patent number: 6416972
    Abstract: Molecular cloning and expression of a prostaglandin F2&agr; receptor which is linked to the signal transduction pathways via guanine nucleotide binding regulatory (G) proteins and measured by, for example, cAMP, IP3 or intracellular calcium. By constructing cell lines that express a prostaglandin F2&agr; receptor, the affinities and efficacies of agonist and antagonist drugs with the receptor can be assessed. A recombinant DNA construct includes a vector and a DNA fragment encoding a prostaglandin F2&agr; receptor. A host cell is transformed with a recombinant DNA construct, so that the DNA fragment is expressed and a prostaglandin F2&agr; receptor is produced. Suitable host systems include eukaryotic and prokaryotic cells, especially mamalian cells such as rat or human. Additionally, for diagnostic purposes, antibodies to a prostaglandin F2&agr; receptor can be prepared by producing all or a portion of the receptor protein and injecting these into various types of mammals.

  • Patent number: 5750369
    Abstract: Molecular cloning and expression of a prostaglandin F2.alpha. receptor which is linked to the signal transduction pathways via guanine nucleotide binding regulatory (G) proteins and measured by, for example, cAMP, IP.sub.3 or intracellular calcium. By constructing cell lines that express a prostaglandin F2.alpha., receptor, the affinities and efficacies of agonist and antagonist drugs with the receptor can be assessed. A recombinant DNA construct includes a vector and a DNA fragment encoding a prostaglandin F2.alpha. receptor. A host cell is transformed with a recombinant DNA construct, so that the DNA fragment is expressed and a prostaglandin F2.alpha., receptor is produced. Suitable host systems include eukaryotic and prokaryotic cells, especially mamalian cells such as rat or human. Additionally, for diagnostic purposes, antibodies to a prostaglandin F2.alpha. receptor can be prepared by producing all or a portion of the receptor protein and injecting these into various types of mammals.
