FUNCTION 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.SUBUNIT Multimeric. Interacts with F8.INTERACTION Localized to storage granules.ALTERNATIVE PRODUCTS Plasma.DOMAIN The von Willebrand antigen 2 is required for multimerization of vWF and for its targeting to storage granules.PTM All cysteine residues are involved in intrachain or interchain disulfide bonds.PTM N- and O-glycosylated.DISEASE The disease is caused by variants affecting the gene represented in this entry.DISEASE The disease is caused by variants affecting the gene represented in this entry.DISEASE The disease is caused by variants affecting the gene represented in this entry.SEQUENCE CAUTION Contaminating sequence.
