Plasminogen, tethered to the cell surface by its association with histidine-rich glycoprotein, is rapidly cleaved and activated to plasmin by the action of urokinase plasminogen activator(two-chain form) bound to uPAR, its cell-surface receptor. The association of both substrate and enzyme with the cell surface is necessary for the reaction to proceed efficiently (Ellis et al. 1989, 1991).
