Hydrophobicity Of Factor Viii On Membrane Binding, Mady Jacobs
Hydrophobicity Of Factor Viii On Membrane Binding, Mady Jacobs
WWU Honors College Senior Projects
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 …

This paper presents readers with an optimized procedure for the purification, activation, and crystallization of selected blood coagulation Factor IX double mutant (FIX_2). Through the completion of this work, we aim to enhance future biochemical and structural studies by providing an easier means for the FIX_2 production, in order to increase understanding of the protein’s function within the blood coagulation cascade. The initiation of the blood coagulation cascade is brought on by activation of inactive Factor VIII (FVIII) protein though contact with tissue factor, the FVIII protein then binds to an activated platelet surface where it must wait for its …
