Gene Information
human ... KNG1(3827) , KNG1 (includes EG:3827)
General description
HK (KNG1) gene is mapped to human chromosome 3q27.3. It is a glycoprotein.
High-molecular-weight kininogen (HK) is the substrate and cofactor of the plasma kallikrein-kinin system (KKS). It is present at a concentration of 660 nM on the plasma and binds to platelet GPI-V-IX complex.
Biochem/physiol Actions
High-molecular-weight kininogen (HK) inhibits binding of thrombin to platelets.
High molecular weight kininogen, two chain, is a participant in contact phase activation of the intrinsic blood coagulation cascade that forms a substrate on which blood factor XI is held in proximity to factor XII allowing reciprocal activation of the two factors. It is also involved in the activation of prekallikrein. High molecular weight kininogen binds to proteoglycans on the surface of platelets, endothelial cells, and other cell types. Domain 5 of high molecular weight kininogen inhibits platelet aggregation and angiogenesis.

The contact system is a potent procoagulant and proinflammatory plasma protease cascade that is initiated by binding ("contact")-induced, auto-activation of factor XII zymogen. Formed active serine protease FXIIa then cleaves plasma prekallikrein to kallikrein that in turn liberates the mediator

Cytoglobin (Cygb) is a cellular haemoprotein belonging to the globin family with ambiguous biological functions. Downregulation of Cygb in many cancers is indicative of its tumour-suppressive role. This is the first report showing the cell cycle regulation of Cygb, which
