Assignment of the {beta}-arrestin 1 gene (ARRB1) to human chromosome 11q13
- Universita di Chieti (Italy); and others
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. {beta}ARK is a member of a multigene family, consisting of six known subtypes, which have also been named G-protein-coupled receptor kinases (GRK 1 to 6) due to the apparently unique functional association of such kinases with this receptor family. The gene for {beta}ARK1 has been localized to human chromosome 11q13. The four members of the arrestin/{beta}-arrestin gene family identified so far are arrestin, X-arrestin, {beta}-arrestin 1, and {beta}-arrestin 2. Here the authors report the chromosome mapping of the human gene for {beta}-arrestin 1 (ARRB1) to chromosome 11q13 by fluorescence in situ hybridization (FISH). Two-color FISH confirmed that the two genes coding for the functionally related proteins {beta}ARK1 and {beta}arrestin 1 both map to 11q13. 16 refs., 1 fig., 1 tab.
