Cloning and expression of the mouse homolog of the human alpha 2-C2 adrenergic receptor.
Three subtypes of alpha 2 adrenergic receptors have been identified in the human and rat. The subtype located on human chromosome 2 (alpha 2-C2) is unique in that it is expressed mainly in the peripheral tissues and lacks sites for N-linked glycosylation. We isolated the gene encoding the mouse homolog of the human alpha 2-C2 adrenergic receptor (M alpha 2-2H). The deduced amino acid sequence of the M alpha 2-2H shows 82% and 96% identity to the human alpha 2-C2 and the rat RNG alpha 2 adrenergic receptors, respectively. Southern blot analysis demonstrated that the M alpha 2-2H was encoded by a single copy gene and was distinct from the mouse homologs of the alpha 2-C4 and alpha 2-C10 adrenergic receptors. When expressed in COS-7 cells, the M alpha 2-2H exhibited a pharmacological profile similar to the human alpha 2-C2 and rat RNG alpha 2 receptors.
