Plasminogen activator urokinase (uPA)

Target
uPA
Molecular classification
Serine protease, Enzyme
01

Overview

Plasminogen activator urokinase (uPA) is a serine protease enzyme that converts inactive plasminogen into active plasmin, crucial for fibrinolysis, tissue remodeling, and pathological processes like cancer invasion and metastasis. It interacts with its receptor, uPAR, to localize proteolytic activity and initiate intracellular signaling.

02

Mechanism of action

Catalyzes the conversion of plasminogen to plasmin, leading to fibrin degradation and ECM remodeling. Binding to uPAR initiates intracellular signaling pathways.
