产品介绍 :   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.

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.

Subunit:
Heterodimer of a light chain and a heavy chain linked by a disulfide bond.

Subcellular Location:
Secreted.

Tissue Specificity:
Plasma.

Post-translational modifications:
The vitamin K-dependent, enzymatic carboxylation of some glutamate residues allows the modified protein to bind calcium.
The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains.

DISEASE:
Defects in F7 are the cause of factor VII deficiency (FA7D) [MIM:227500]. A hemorrhagic disease with variable presentation. The clinical picture can be very severe, with the early occurrence of intracerebral hemorrhages or repeated hemarthroses, or, in contrast, moderate with cutaneous-mucosal hemorrhages (epistaxis, menorrhagia) or hemorrhages provoked by a surgical intervention. Finally, numerous subjects are completely asymptomatic despite very low factor VII levels.

Similarity:
Belongs to the peptidase S1 family.
Contains 2 EGF-like domains.
Contains 1 Gla (gamma-carboxy-glutamate) domain.
Contains 1 peptidase S1 domain.

SWISS:
P08709

Gene ID:
2155

凝血因子7是肝脏合成的一种维生素K依赖性的单链糖蛋白,由4 0 6个氨基酸残基组成,分子量约45kD。 凝血因子Ⅶ的半衰期短（4～6h），血浆含量较低（0.5～2mg/L），故可作为肝病患者蛋白质合成功能减退的早期诊断指标。在慢性肝病患者通过肝活检组织原位杂交的方法检测到凝血因子Ⅶ的表达与肝纤维化的分级呈负相关，可作为预测纤维化程度的指标。凝血因子Ⅶ活性还与预后有着密切的联系，经研究认为：凝血因子Ⅶ活性<34%的肝硬化患者93%在随访10月内死亡，故认为它是肝硬化患者预后坏的早期预测指标，可更识别肝移植候选人。肝硬化患者凝血因子Ⅶ活性可明显下降，凝血因子Ⅶ缺乏可导致血小板活性的改变，结合血小板计数减少使出血时间延长，因此对有创诊断与治疗的肝硬化患者，还应该用凝血因子Ⅶ活性进行出血危险度的评估，而不能仅看血小板计数。除诊断之外，重组凝血因子Ⅶ可以有效地纠正肝病患者凝血异常，有利于有创性检查的进行。
