    Two types of proteins play a major role in determining homologous desensitization of G-coupled receptors: beta-adrenergic receptor kinase (beta ARK), which phosphorylates the agonist-occupied receptor and its functional cofactor, beta-arrestin. Both beta ARK and beta-arrestin are members of multigene families. The family of G-protein-coupled receptor kinases includes rhodopsin kinase, beta ARK1, beta ARK2, IT11-A (GRK4), GRK5, and GRK6. The arrestin/beta-arrestin gene family includes arrestin (also known as S-antigen), beta-arrestin 1, and beta-arrestin 2. Here we report the chromosome mapping of the human genes for arrestin (SAG), beta-arrestin 2 (ARRB2), and beta ARK2 (ADRBK2) by fluorescence in situ hybridization (FISH). FISH results confirmed the assignment of the gene coding for arrestin (SAG) to chromosome 2 and allowed us to refine its localization to band q37. The gene coding for beta-arrestin 2 (ARRB2) was mapped to chromosome 17p13 and that coding for beta ARK2 (ADRBK2) to chromosome 22q11.
