cDNA cloning and chromosomal localization of the human beta-adrenergic receptor kinase.
The beta-adrenergic receptor kinase (beta ARK) mediates agonist-dependent phosphorylation of the beta 2-adrenergic and related G protein-coupled receptors. A cDNA encoding bovine beta ARK has recently been isolated. In this work we have isolated a cDNA encoding human beta ARK from a retinal cDNA library. The cDNA encodes a protein of 689 amino acids with an overall 98.0% amino acid and 92.5% nucleotide identity with bovine beta ARK. Chromosomal location of the human beta ARK gene was determined by correlating the presence of the beta ARK locus with retention of a specific human chromosome in a rodent-human hybrid panel. This analysis revealed that the human beta ARK locus segregated with the long arm of chromosome 11, centromeric to 11q13.
