General Information of Binding Target of SBP (BTS) (ID: ST00577)
BTS Name
Coagulation factor XII
Synonyms
Hageman factor; HAF; EC:3.4.21.38
BTS Type
Protein
Family
peptidase S1 family
Gene Name
F12
Organism
Homo sapiens (Human)
Function
Factor XII is a serum glycoprotein that participates in the initiation of blood coagulation, fibrinolysis, and the generation of bradykinin and angiotensin. Prekallikrein is cleaved by factor XII to form kallikrein, which then cleaves factor XII first to alpha-factor XIIa and then trypsin cleaves it to beta-factor XIIa. Alpha-factor XIIa activates factor XI to factor XIa.
