Fibrinopeptide A binds Gly-Pro-Arg-Pro.
The tetrapeptide Gly-Pro-Arg-Pro inhibits fibrinogen aggregation, probably by binding to the same sites used during initiation of fibrin formation. The Gly-Pro-Arg-Pro binding sites have not yet been identified. However, their possible sequence and locations have been predicted on the basis of the amino acid pairing hypothesis. One of these predicted sites is on fibrinopeptide A. We report here...
متن کاملMechanisms of Arg-Pro-Pro-Gly-Phe inhibition of thrombin.
Investigations determined the mechanism(s) by which Arg-Pro-Pro-Gly-Phe (RPPGF) inhibits thrombin-induced platelet activation. High concentrations of RPPGF inhibit thrombin-induced coagulant activity. RPPGF binds to the active site of thrombin by forming a parallel beta-strand with Ser214-Gly216 and interacts with His57, Asp189, and Ser195 of the catalytic triad. RPPGF competitively inhibits al...

Human endogenous retroviruses (HERVs) are a family of viruses within our genome with similarities to present day exogenous retroviruses. HERVs have been inherited by successive generations and it is possible that some have conferred biological benefits. However, several HERVs have been implicated in certain cancers and autoimmune diseases. This article demystifies these retroviruses by providin...

متن کاملThe use of the synthetic peptide, Gly-Pro-Arg-Pro, in the preparation of thrombin-degranulated rabbit platelets.
The method for preparing thrombin-degranulated platelets has been modified to avoid the use of plasmin or successive treatments with small amounts of thrombin, while still achieving more than 90% release of platelet amine storage granule contents. It was necessary to prevent the fibrinogen released from the platelets during thrombin treatment from forming an insoluble fibrin mesh that could tra...
