Abstract
A mammalian D2 dopamine receptor gene has been cloned. Thus, DNA sequences encoding all or a part of the dopamine receptor are provided, as well as the corresponding polypeptide sequences and methods for producing the same both synthetically and via expression of a corresponding sequence from a host transformed with a suitable vector carrying the corresponding DNA sequence. The various structural information provided by this invention enables the preparation of labeled or unlabeled immunospecific species, particularly antibodies, as well as nucleic acid probes labeled in conventional fashion. Pharmaceutical compositions and methods of using various products of this invention are also provided.
Claims8
A cell membrane preparation obtained from a cell that expresses an exogenous gene encoding a mammalian D2 dopamine receptor, wherein said exogenous mammalian D2 dopamine receptor-encoding gene is from a mammalian species different from the species of the cell in which the exogenous gene is expressed, and wherein said exogenous mammalian D2 dopamine receptor-encoding gene has an amino acid sequence identified as the amino acid sequence of FIG. 7A-C, FIG. 18A-H or FIG. 18A-H wherein amino acids 242-270 are deleted therefrom.
A cell membrane preparation comprising a mammalian D2 dopamine receptor having an amino acid sequence identified as the amino acid sequence of FIG. 7A-C, FIG. 18A-H or FIG. 18A-H wherein amino acids 242-270 are deleted therefrom, wherein the membrane preparation homogeneously comprises no other mammalian dopamine receptor type.
A cell membrane preparation comprising a mammalian D2 dopamine receptor having an amino acid sequence identified as the amino acid sequence of FIG. 7A-C, FIG. 18A-H or FIG. 18A-H wherein amino acids 242-270 are deleted therefrom, wherein the membrane preparation homogeneously contains dopamine receptors that are none other than said mammalian D2 dopamine receptor.
