    摘要: Chimeric G-protein linked receptors are constructed which retain ligand binding specificity yet gain the ability to elevate intracellular free calcium as a result of agonist binding. This easily assayed function is provided by the insertion of or replacement with sequences substantially homologous to the i3 loop of a second G-protein-linked receptor. Such receptors are employed, for example, in methods of screening for compounds capable of acting as agonists or antagonists of G-protein-linked receptors.
