    basic FUNCTION
  • triggering the middle phase of the intrinsic pathway of blood coagulation by activating factor IX
  • promotes hemostasis and thrombosis through enhancement of thrombin generation and may play a critical role in the formation of occlusive thrombi in arterial injury models (White-Adams 2009)
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS coagulation/hemostasis
    PATHWAY
    metabolism
    signaling
    a component
  • homodimer consisting of two identical polypeptide chains linked by disulfide bonds and during activation of the plasma factor XI, an internal peptide bond is cleaved by factor XIIa (or XII) in each of the two chains, resulting in activated factor XIa
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting with LRP8 (a platelet receptor for FXI) (White-Adams 2009)
    • cell & other
    REGULATION
    activated by FXIIa producing a serine protease composed of two heavy and two light chains
    FXIIa and thrombin (dimeric structure of FXI is essential for normal proteolytic activation of FXI by FXIIa, thrombin, or FXIa either in solution or on an anionic surface but not for FIX activation by FXIa in solution)(Wu 2008)
