+== Disease ==
+[https://www.uniprot.org/uniprot/UROK_HUMAN UROK_HUMAN] Defects in PLAU are the cause of Quebec platelet disorder (QPD) [MIM:[https://omim.org/entry/601709 601709]. QPD is an autosomal dominant bleeding disorder due to a gain-of-function defect in fibrinolysis. Although affected individuals do not exhibit systemic fibrinolysis, they show delayed onset bleeding after challenge, such as surgery. The hallmark of the disorder is markedly increased PLAU levels within platelets, which causes intraplatelet plasmin generation and secondary degradation of alpha-granule proteins.<ref>PMID:20007542</ref>

+== Publication Abstract from PubMed ==
+Two isomeric piperidine derivatives (meta and para isomers) were used as arginine mimics in the P1 position of a cyclic peptidic inhibitor (CPAYSRYLDC) of urokinase-type plasminogen activator. The two resulting cyclic peptides showed vastly different affinities ( approximately 70 fold) to the target enzyme. X-ray crystal structure analysis showed that the two P1 residues were inserted into the S1 specificity pocket in indistinguishable manners. However, the rest of the peptides bound in entirely different ways on the surface of the enzyme, and the two peptides have different conformations, despite the highly similar sequence. These results demonstrate how the subtle difference in P1 residue can dictate the exosite interactions and the potencies of peptidic inhibitors, and highlight the importance of the P1 residue for protease inhibition. This study provides important information for the development of peptidic agents for pharmacological intervention.
