Alpha-2 antiplasmin (α2AP)

Target
α2AP
Molecular classification
Serine protease inhibitors (serpins)
01

Overview

Alpha-2 antiplasmin (α2AP), also known as plasmin inhibitor, is a key serine protease inhibitor (serpin) that plays a central role in regulating fibrinolysis by inactivating plasmin, the primary enzyme responsible for breaking down blood clots. It is primarily synthesized by hepatocytes in the liver and released into circulation.

Other names
