Urokinase plasminogen activator (uPA) is a serine protease. It converts the abundant proenzyme
plasminogen to active plasmin and plays a key role in cancer invasion and a variety of tissue
remodelling processes such as wound healing, mammary gland involution and placental development. Elevated levels of uPA are associated with poor prognosis in many types of cancer.
