Abstract:
Protein phosphatase (PP) activities have long been known in platelets, but their physiological roles in platelet reactions are not well understood. Since the discovery of the okadaic acid (OA) class of compounds, potent and cell-permeable PP 1/2A inhibitors, evidence for the active involvement of PP1/2A in platelet reactions has rapidly accumulated. This article reviews the possible involvement of PP1/2A in platelet function by focusing on the effects of OA class compounds on agonist-induced platelet reactions.

Protein kinases
Many proteins in the cell are regulated by phosphorylation, the addition of a phosphate group. A family of enzymes called kinases...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
