ADAM metallopeptidase with thrombospondin type 1 motif, 13; Cleaves the vWF multimers in plasma into smaller forms
VWF [ENSP00000261405]
 
von Willebrand factor; 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
