Target
Function
Coagulation factor XII, also known as Hageman factor, is a plasma protein involved in coagulation. It is the zymogen form of factor XIIa (EC 3.4.21.38), an enzyme of the serine protease (or serine endopeptidase) class. In humans, factor XII is encoded by F12 gene. Factor XII (FXII, Hageman factor) is a plasma glycoprotein of approximately 90 kDa and is part of the coagulation cascade. It activates factor XI and prekallikrein in vitro. FXII is activated to FXIIa by negatively charged surfaces such as glass, initiating the intrinsic pathway. FXII also plays a role in diagnostic coagulation assays called activated partial thromboplastin times (aPTT). In vivo, FXII is activated by binding to polyanions in a process termed contact activation. Various polymers, such as kaolin and glass, act as non-physiological activators of FXII. Activated platelets release inorganic polyphosphates, which activate FXII, initiating the intrinsic pathway and contributing to fibrin formation and thrombus development. Polyphosphates also accelerate thrombin-induced activation of factor XI. Polyphosphate forms calcium-rich nanoparticles in vivo, which accumulate on platelets and activate FXII. The regulation of platelet polyphosphates is still not fully understood, but the phosphate-exporter XPR1 has been identified as a key regulator. Targeting XPR1 increases polyphosphate levels, accelerating thrombosis in mouse models. Given FXII’s role in thrombosis while sparing hemostasis, it has become a target for anticoagulant drug development. Inhibitors targeting FXII are in clinical trials.
