Amino Acid Sequence

Ala-Tyr-Pro-Gly-Lys-Phe-NH2

Description générale

Ala-Tyr-Pro-Gly-Lys-Phe-NH2 (AYPGKF- NH2) is a selective, specific proteinase-activated receptor 4 (PAR4) agonist peptide. PAR4 is a G-protein-coupled receptor that is expressed on the surface of human platelets and is involved in the thrombin signaling pathway. Cleavage of PAR4 by the protease thrombin stimulates the receptor and results in signaling of platelet aggregation.

Application

4-Androsten-11β-ol-3,17-dione has been used in platelet aggregation.
AYPGKF- NH2 may be used for probing PAR4 signaling in culture systems and in platelets.

Actions biochimiques/physiologiques

AYPGK is a ligand for the PAR4 receptor; binding results in activation of PAR4. AYPGK stimulates platelet aggregation in vitro (EC50 =15 μM) via PAR4. In human platelets treated with the PAR4 agonist, AYPGKF stimulates the production of thromboxane, a potent agent for platelet-aggregation. Additionally, AYPGKF mediates the thrombin-induced release of endostatin from rat platelets.

Previous reports have indicated that thrombin-induced thromboxane production by human platelets occurs through two types of interaction between thrombin and the platelet surface. One of these interactions is with protease activated receptor(PAR)-1, the first identified thrombin receptor. These studies were

Human platelets display a unique dual receptor system for responding to its primary endogenous activator, α-thrombin. Because of the lack of efficacious antagonists, the field has relied on synthetic peptides and pepducins to describe protease-activated receptor PAR1 and PAR4 signaling.
