Chаpter 11: Yоu’re studying cellulаr signаling thrоugh G-Prоtein Coupled Receptors (GPCRs). Specifically, you’re working on a pair of newly identified GPCRs, GPCR-A and GPCR-B. Each binds the same small ligand but activates different heterotrimeric G-proteins that act on adenylyl cyclase. A (3 points). Your grad student mentor explains that both the receptors and the Gα and Gβγ subunits of the heterotrimeric G-proteins are membrane-associated. You’re puzzled because although you find obvious transmembrane domains in the receptor, you find none in Gα or Gβγ. How are G-proteins specifically the Gα and Gβγ subunits associated with the membrane (be specific)? You find that the binding of ligand has opposite effects on adenylyl cyclase activity for each receptor. GPCR-A causes an increase in adenylyl cyclase activity, while GPCR-B causes a decrease in adenylyl cyclase activity. B (1 points). Based on the above-stated effects on adenylyl cyclase activity, what type of G-protein is activated by each receptor?
