Abstract

Factor VIII (FVIII) plays a crucial role in our body’s ability to prevent blood loss. This function comes from its ability to bind membranes and enhance catalytic function of other proteins. Membrane binding of FVIII relies on hydrophobic residues located at the lower C2 domain in a region named the PS head group. This study looks at how the enhancement of the hydrophobicity of this site can impact the protein binding ability to membranes. Specifically mutating the residues leucine at residue 2251 in the PS head group to phenylalanine, the study uses BLI instrumentation to determine whether this mutation can induce increased activity of FVIII. Results obtained find that this mutation reduces membrane binding capabilities despite its increase in hydrophobicity. These results are believed to be related to structural changes that may have occurred specifically to the PS binding region of the C2 domain.
