Abstract:
Protein Z (PZ) is a vitamin K-dependent protein. As a cofactor for the protein Z-dependent protease inhibitor (ZPI), it inhibits coagulation factor X under the existence of phospholipid and calcium ion, and increases the ZPI activity by nearly 1000-fold, thus it plays a role in the process of thrombosis. ZPI inhibits coagulation factor Ⅺ a alone. ZPI activity is also consumed in the process of inhabiting factor Ⅹa and Ⅺa. This article reviews the biological characteristics of PZ and ZPI and their association with stroke.
