DISCUSSION During fasting, one of the major effects of both glucagon and glucocorticoids is to stimulate hepatic glucose production.
This insulin signal transduction pathway is composed of trigger mechanisms (e. g.autophosphorylation mechanisms) that serve as signals throughout the cell. There is also a counter mechanism in the body to stop the secretion of insulin beyond a certain limit. Namely, those counterregulatory mechanisms are glucagon and epinephrine. The Glycogenolysis Signaling Cascade During the fightorflight response the body needs to get energy to the muscles in the form of sugar molecules.
One of the methods used to do that is called glycogenolysis. The signal molecules epinephrine and glucagon bind to specific 7TM receptors in the plasma membranes of muscle and liver cells, respectively. Epinephrine binds to the adrenergic receptor in muscle, whereas glucagon binds to the glucagon receptor. These binding events activate the subunit of the heteromeric G s protein.
Other signal transduction proteins interact with IRS including GRB2, an adaptor protein that contains SH3 domains, which in turn associates with the guanine nucleotide exchange factor sonof sevenless (SOS) and elicits activation of the MAPK cascade leading to mitogenic responses (Ogawa et al.1998).
