Amino Acid Sequence

Gly-Pro-Arg-Pro-NH2

General description

Gly-Pro-Arg-Pro is a peptide that mimics the N-terminal Gly-Pro-Arg region in the a chain of fibrin protein.

Application

Gly-Pro-Arg-Pro amide has been used-
  • as a constituent of buffer during fluid-phase and bound thrombin inhibition assays, to determine the activity of thrombin
  • for blocking fibrin polymerization and preventing fibrin clot formation in presence of α-thrombin, in blood obtained from mice
  • during preparation of human soluble fibrin, to block the polymerization of soluble fibrin

Biochem/physiol Actions

Gly-Pro-Arg-Pro peptide suppresses the early steps of fibrin polymerization. The amide derivative of this peptide prevents the degradation of fibrinogen and fragment D by plasmin, even in the presence of EGTA (ethylene glycol-bis(β-aminoethyl ether)-N,N,N′,N′-tetraacetic acid).

Packaging

Although fibrin-bound thrombin is resistant to inactivation by heparin.antithrombin and heparin.heparin cofactor II complexes, indirect studies in plasma systems suggest that the dermatan sulfate.heparin cofactor II complex can inhibit fibrin-bound thrombin.

Heparin-induced thrombocytopenia (HIT) is a well-characterized, iatrogenic complication of heparin anticoagulation with significant morbidity. In contrast, vaccine-induced immune thrombotic thrombocytopenia (VITT) is a recently recognized severe prothrombotic complication of adenoviral vaccines, including the ChAdOx1 nCoV-19 (Vaxzevria, AstraZeneca) and Ad26.COV2.S (Janssen
