Factor XII (Hageman factor) is a single chain glycoprotein (MW 80,000).
It is a serine protease zymogen.
FXII is converted to an active enzyme by damage to vascular endothelium.
In vitro activation is caused by glass or kaolin.
Surface binding promotes activation by kallikrein.
FXIIa activates prekallikrein and FXI.
Kallikrein activates more FXII.
Fragments of FXIIa activate FVII to FVIIa, and plasminogen to plasmin.
The complement system is also activated by FXIIa.
A link between fibrin clot and the subendothelium is formed by FXIIa crosslinking with fibrin, alpha-2 plasmin inhibitor, fibronectin and Van Willebrand factor.
