  • Binding of [3H] Rauwolscine to membranes from cells stably expressing the ADRA2A receptor. Membranes from recombinant CHO-K1 cells expressing the ADRA2A receptor were isolated and stored frozen. Radioligand binding studies were performed by incubating membranes with the indicated concentration of [3H] Rauwolscine for 60 min at room temperature, then filtering rapidly over GF/C filters which were then counted in an LSC. Data represent averages of duplicate determinations. Norepinephrine (100 µM) was used to define non-specific binding (black triangles).
  • ADRA2A-mediated inhibition of intracellular cAMP accumulation. Cells stably expressing the ADRA2A receptor (red) or untransfected CHO-K1 cells (black) were exposed to the indicated concentrations of UK14304 for 30 min at 37oC with 10 µM forskolin and 1 mM IBMX. Intracellular cAMP was assayed using the HitHunter kit (DiscoveRx).

Quick Overview

Human Alpha2a Adrenergic Receptor-expressing GPCR (G protein-coupled receptor) stable, replicating cell line.

Background

Three alpha2-adrenoceptors have been cloned, and are designated alpha2a, alpha2b and alpha2c. All three receptors are activated by norepinephrine and all three are coupled via Gi to adenylate cyclase. The alpha2a adrenergic receptor is widely distributed in the CNS, lung, blood vessels and skeletal muscle and mediates vasoconstriction and inhibition of neurotransmission.
