Abstract
An alpha 2-adrenergic receptor subtype has been cloned from a human kidney cDNA library using the gene for the human platelet alpha 2-adrenergic receptor as a probe. The deduced amino acid sequence resembles the human platelet alpha 2-adrenergic receptor and is consistent with the structure of other members of the family of guanine nucleotide-binding protein-coupled receptors. The cDNA was expressed in a mammalian cell line (COS-7), and the alpha 2-adrenergic ligand [3H]rauwolscine was bound. Competition curve analysis with a variety of adrenergic ligands suggests that this cDNA clone represents the alpha 2B-adrenergic receptor. The gene for this receptor is on human chromosome 4, whereas the gene for the human platelet alpha 2-adrenergic receptor (alpha 2A) lies on chromosome 10. This ability to express the receptor in mammalian cells, free of other adrenergic receptor subtypes, should help in developing more selective alpha-adrenergic ligands.

Studies of the mechanisms of action and regulation of hormones and neurotransmitters at the cellular and molecular levels constitute the main goals our of research activities. G protein-coupled receptors (GPCR) mediate the actions of signaling molecules from unicellular organisms to man. We have used adrenergic and dopamine receptors to characterize the structure/function and regulation mechanisms of these prototypes of G protein-coupled receptors. Another approach has been to characterize
