Anti-Factor VII

0.5mg/ml if reconstituted with 0.2ml sterile DI water. Coagulation Factor VII, also known as proconvertin, is one of the proteins that causes blood to clot in the coagulation cascade. It is an enzyme of the serine protease class. The F7 gene maps to chromosome 13q34(Millar et al., 2000). Synthesis of factors VII and X, as well as factors II and IX, takes place in the liver and requires vitamin K. Structural homologies of these factors, which are precursors of serine proteases, have been shown(Zur and Nemerson, 1981). Di Bitondo et al.(2002) used reporter gene analysis to show that inclusion of promoter regions of F7 reduced transcription activity in the presence of estrogenic factors. The effect was independent of promoter polymorphic haplotype. Protein function: Initiates the extrinsic pathway of blood coagulation. Serine protease that circulates in the blood in a zymogen form. Factor VII is converted to factor VIIa by factor Xa, factor XIIa, factor IXa, or thrombin by minor proteolysis. In the presence of tissue factor and calcium ions, factor VIIa then converts factor X to factor Xa by limited proteolysis. Factor VIIa will also convert factor IX to factor IXa in the presence of tissue factor and calcium. [The UniProt Consortium]
