Abstract
Background: It is unclear how the LDL receptor family binds large protein ligands. Results: HDX and lysine scanning identified factor (F)VIII regions and specific lysine residues binding low-density lipoprotein receptor-related protein 1 (LRP1). Conclusion: FVIII-LRP1 interaction involves multiple "hot-spot" lysine residues in the A3C1 domains. Significance: Our study sheds light
