  • Title: The role of the C-terminal domain in the inhibitory functions of tissue factor pathway inhibitor.
    Author: Ettelaie C, Adam JM, James NJ, Oke AO, Harrison JA, Bunce TD, Bruckdorfer KR.
    Journal: FEBS Lett; 1999 Dec 17; 463(3):341-4. PubMed ID: 10606750.
    Abstract:
    Tissue factor pathway inhibitor (TFPI) inhibits the activity of coagulation factors VIIa and Xa through Kunitz domains, thereby inhibiting the activity of tissue factor. However, it has been shown that the C-terminal of this inhibitor is essential for the maximal anticoagulant activity of TFPI. We have investigated the endogenous ability of the C-terminal of TFPI to influence coagulation. A synthetic peptide corresponding to residues 254-265 within the C-terminal of TFPI was prepared and shown to be capable of inhibiting tissue factor pathway by preventing the activation of factor VII. Mutational analysis of the peptide revealed the identity of the key lysine residues.
