Association with the D'D3 domain of von Willebrand factor (VWF) stabilizes factor
VIII (FVIII) in the circulation and maintains it at a level sufficient to prevent
spontaneous bleeding. We used negative-stain electron microscopy (EM) to
visualize complexes of FVIII with dimeric and monomeric forms of the D'D3 domain.
The EM averages show that FVIII interacts with the D'D3 domain primarily through
its C1 domain, with the C2 domain providing a secondary attachment site.
Hydrogen-deuterium exchange mass spectrometry corroborated the importance of the
C1 domain in D'D3 binding and implicates additional surface regions on FVIII in
the interaction. Together, our results establish that the C1 domain is the major
binding site on FVIII for VWF, reiterate the importance of the a3 acidic peptide
in VWF binding, and suggest that the A3 and C2 domains play ancillary roles in
this interaction.
