Functional and Molecular Characterization of C91S Mutation in the Second Epidermal Growth Factor-like Domain of Factor VII
Background: Coagulation Factor VII is a vitamin K-dependent serine protease which has a pivotal role in the initiation of the coagulation cascade. The congenital Factor VII deficiency is a recessive hemorrhagic disorder that occurs due to mutations of F7 gene. In the present study C91S (p.C91S) substitution was detected in a patient with FVII deficiency. This mutation has not b...
متن کاملSecretion of an epidermal growth factor-like growth factor by epidermal growth factor-independent rat mammary carcinoma cells.
Rat mammary carcinoma (RMC) cells derived from serially transplantable mammary tumors are independent of epidermal growth factor (EGF) for long-term growth in serum-free medium. This phenotype is in contrast to that of normal mammary epithelial cells or cells derived from nontransplantable tumors that express an absolute requirement for EGF for growth in culture. The results of the experiments ...
متن کاملSequences required for thrombomodulin cofactor activity within the fourth epidermal growth factor-like domain of human thrombomodulin.
Activation of protein C by thrombin is stimulated by the endothelial cell cofactor thrombomodulin. The structural regions of thrombomodulin necessary for cofactor activity have been localized to the fourth through sixth epidermal growth factor (EGF)-like domains. The fourth EGF-like domain is unnecessary for high affinity thrombin binding, but is required for cofactor activity. To identify esse...
متن کاملTenascin cytotactin epidermal growth factor-like repeat binds epidermal growth factor receptor with low affinity.
Select epidermal growth factor (EGF)-like (EGFL) repeats of human tenascin cytotactin (tenascin C) can stimulate EGF receptor (EGFR) signaling, but activation requires micromolar concentrations of soluble EGFL repeats in contrast to subnanomolar concentrations of classical growth factors such as EGF. Using in silico homology modeling techniques, we generated a structure for one such repeat, the...
متن کاملDynamics of the fragment of thrombomodulin containing the fourth and fifth epidermal growth factor-like domains correlate with function.
Thrombomodulin (TM) forms a 1:1 complex with thrombin. Whereas thrombin alone cleaves fibrinogen to make the fibrin clot, the thrombin-TM complex cleaves protein C to initiate the anticoagulant pathway. The fourth and fifth EGF-like domains of TM together form the minimal fragment with anticoagulant cofactor activity. A short linker connects the fourth and fifth EGF-like domains of TM, and Met ...
