    摘要: A recombinant cell comprising a host cell containing a recombinant DNA sequence is disclosed. The recombinant DNA sequence comprises vector DNA and DNA which encodes a mammalian adrenergic receptor. The host cell is one capable of undergoing proliferation in response to activation of the adrenergic receptor. In one specific embodiment of the foregoing, the adrenergic receptor includes a mutation in the third cytoplasmic loop thereof which renders the adrenergic receptor constitutively active, and the host cell undergoes proliferation in response to the constitutively active adrenergic receptor. Also disclosed are in vitro assays employing the foregoing which are useful for screening test compounds for antitumor and antiatherogenic activity, along with a diagnostic assay for detecting the oncogenic activation of cells in a patient. The diagnostic assay comprises collecting sample cells which express adrenergic receptors from the patient, and then detecting the presence or absence of a mutation in the adrenergic receptor which renders the receptor constitutively active. The presence of such a mutation indicates the oncogenic activation of the cells.

    摘要: Disclosed is a transformed yeast cell containing a first heterologous DNA sequence which codes for a mammalian G protein-coupled receptor and a second heterologous DNA sequence which codes for a mammalian G protein α subunit (mammalian Gα). The first and second heterologous DNA sequences are capable of expression in the cell, but the cell is incapable of expressing an endogenous G protein α-subunit (yeast Gα). The cells are useful for screening compounds which affect the rate of dissociation of Gα from Gβγ in a cell. Also disclosed is a novel DNA expression vector useful for making cells as described above. The vector contains a first segment comprising at least a fragment of the extreme amino-terminal coding sequence of a yeast G protein-coupled receptor. A second segment is positioned downstream from the first segment (and in correct reading frame therewith), with the second segment comprising a DNA sequence encoding a heterologous G protein-coupled receptor.

    摘要: The anatomical distribution, nucleic acid sequence, pharmacological properties, and inferred structural features of a cDNA encoding a high affinity, Na.sup.+ -dependent rat brain L-proline transporter is described. The expression of this carrier in subpopulations of putative glutamatergic pathways supports a specific role for L-proline in excitatory amino acid neurotransmission. The cloned transporter cDNA predicts a 637 amino acid protein with 12 putative transmembrane domains and exhibits 44%-45% amino acid sequence identity with other neurotransmitter transporters. These findings support a synaptic role for L-proline in specific excitatory pathways in the CNS. The sequence can be used for expression of the transporter molecule, to make probes for the same protein from other species and related proteins, in diagnostic assays, and to design functional and structural analogs for use in research and possible clinical treatments. The protein is useful in making antibodies, conducting research studies, and design of therapeutic transporter modulators for clinical treatments.

    摘要: Cloned genes which code for the D.sub.1 dopamine receptor are disclosed. The receptors coded for by these clones bind dopamine ligands with the proper pharmacological profile and, when expressed in the cell membrane of a suitable host and so bound, stimulate adenylyl cyclase. Also disclosed are vectors comprising a cloned gene encoding a D.sub.1 -dopamine receptor, cells transformed with such vectors, and oligonucleotide probes capable of selectively hybridizing to DNA comprising a portion of a gene coding for a D.sub.1 -dopamine receptor. The cloned genes are useful for making proteins and cell membrane preparations which can be used to screen compounds for D.sub.1 -dopamine receptor binding activity, are useful in molecular biology, and are useful as diagnostic probes.
