Amino Acid Sequence

Gly-Pro-Arg-Pro

General description

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

Application

Gly-Pro-Arg-Pro (GPRP) has been used for the formation of crystal composed of GPRP and the 30kDa C-terminal fragment from the γ chain of fibrinogen (rFbgγC30), cloned and expressed in Pichia pastoris.

Biochem/physiol Actions

Gly-Pro-Arg-Pro (GPRP) is capable of increasing free thrombin. Thus it can be utilized to make thrombin-degranulated platelets, which helps in studying platelet reactions.
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).
Inhibits fibrin polymerization.

The present paper shows that conformationally changed fibrinogen can expose the sites A alpha-(148-160) and gamma-(312-324) involved in stimulation of the tissue-type plasminogen activator (t-PA)-catalysed plasminogen activation. The exposure of the stimulating sites was determined by ELISA using mABs directed
