Factor Xa (FXa)

Target
FXa
Molecular classification
Serine endopeptidase, Serine protease, Enzyme
01

Overview

Factor Xa is the activated form of coagulation factor X, a serine endopeptidase that plays a central role in the blood coagulation cascade. It catalyzes the conversion of prothrombin to thrombin, a key step in clot formation. Inhibition of factor Xa is an effective strategy for anticoagulant therapy.

Other names
Activated Coagulation Factor XThrombokinase
02
