靶标

  • 功能Important in the maintenance of hemostasis, it promotes adhesion of platelets to the sites of vascular injury by forming a molecular bridge between sub-endothelial collagen matrix and platelet-surface receptor complex GPIb-IX-V. Also acts as a chaperone for coagulation factor VIII, delivering it to the site of injury, stabilizing its heterodimeric structure and protecting it from premature clearance from plasma.
  • 组织特异性Plasma.
  • 疾病相关Defects in VWF are the cause of von Willebrand disease (VWD) [MIM:277480]. VWD defines a group of hemorrhagic disorders in which the von Willebrand factor is either quantitatively or qualitatively abnormal resulting in altered platelet function. Symptoms vary depending on severity and disease type but may include prolonged bleeding time, deficiency of factor VIII and impaired platelet adhesion. Type I von Willebrand disease is the most common form and is characterized by partial quantitative plasmatic deficiency of an otherwise structurally and functionally normal Willebrand factor; type II is associated with a qualitative deficiency and functional anomalies of the Willebrand factor; type III is the most severe form and is characterized by total or near-total absence of Willebrand factor in the plasma and cellular compartments, also leading to a profound deficiency of plasmatic factor VIII.
  • 序列相似性Contains 1 CTCK (C-terminal cystine knot-like) domain.
    Contains 4 TIL (trypsin inhibitory-like) domains.
    Contains 3 VWFA domains.
    Contains 3 VWFC domains.
    Contains 4 VWFD domains.
  • 结构域The von Willebrand antigen 2 is required for multimerization of vWF and for its targeting to storage granules.
  • 翻译后修饰All cysteine residues are involved in intrachain or interchain disulfide bonds.
    N- and O-glycosylated.
  • 细胞定位Secreted. Secreted > extracellular space > extracellular matrix. Localized to storage granules.
