Thrombin-activatable fibrinolysis inhibitor

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Thrombin-activatable fibrinolysis inhibitor (TAFI), also known as plasma carboxypeptidase B2 is a recently described plasma zymogen that, when exposed to the thrombin–thrombomodulin complex, is converted by proteolysis at Arg92 to a basic carboxypeptidase (TAFIa or activated TAFI) that inhibits fibrinolysis.

TAFI is produced by the liver.
