Abstract

The regulation and functional significance of the palmitoylation status of G-protein-linked receptors and G-proteins will be analysed in cell systems in which the maintained presence of an agonist results in downregulation of both the receptor and its associated G-protein. The dynamics of palmitoylation of these polypeptides, how this is controlled by receptor agonists and whether alteration in the palmitoylation status compromises the physical interactions between receptors and G-proteins will be assessed. Palmitoylation resistant mutants of both Gila and Gola will be further modified to eliminate sensitivity to pertussis toxin allowing the interactions of these G-proteins with receptors to be monitored directly even in the presence of endogenously expressed wild type pertussis toxin-sensitive G-proteins. There is considerable interest in the pharmaceutical industry in means to control the lapidation status of a variety of signal transducing polypeptides and the current studies will provide highly novel information on the significance of dynamic acylation.
