Human urokinase-type plasminogen activator (uPA) is poorly secreted by yeast cells. Here, we have selected Hansenula polymorpha mutants with increased productivity of active extracellular uPA. Several of the obtained mutants also demonstrated a defect of sorting of carboxypeptidase Y to the vacuole and the mutant loci have been identified in six of them. All these mutations damaged genes involved in protein traffic between the Golgi apparatus and the vacuole, namely PEP3, VPS8, VPS10, VPS17, and VPS35. We have shown that inactivation of the VPS10 gene encoding the vacuolar protein sorting receptor does not increase uPA secretion but stimulates its proteolytic processing.
