The signal transducing system coupled to serotonin-S2 receptors

Abstract
The signal transducing system coupled to the serotonin-S2 receptor on platelets involves metabolism of inositolcontaining phospholipid, elevation of intracellular free Ca2+ and activation of protein kinase C. Evidence for coupling of the serotonin-S2 receptor to the same signal transducing system in brain and smooth muscle tissue is reviewed.
