== 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> 
== Function ==
[https://www.uniprot.org/uniprot/UROK_HUMAN UROK_HUMAN] Specifically cleaves the zymogen plasminogen to form the active enzyme plasmin.

== Publication Abstract from PubMed ==
The urokinase receptor (uPAR) can recognize several ligands. The structural basis for this multiple ligand recognition by uPAR is unknown. This study reports the crystal structures of uPAR in complex with both urokinase (uPA) and vitronectin and reveal that uPA occupies the central cavity of the receptor, whereas vitronectin binds at the outer side of the receptor. These results provide a structural understanding of one receptor binding to two ligands.
