**Background of PLAU Recombinant Protein**
The plasminogen activator, urokinase (PLAU), also known as urokinase-type plasminogen activator (uPA), is a serine protease encoded by the *PLAU* gene. It plays a critical role in extracellular matrix (ECM) degradation by converting plasminogen into plasmin, a broad-spectrum protease involved in fibrinolysis, tissue remodeling, and cell migration. Structurally, PLAU consists of an N-terminal growth factor-like domain, a kringle domain, and a catalytic serine protease domain. Its activity is tightly regulated by interactions with its receptor (uPAR) and inhibitors like PAI-1.
Recombinant PLAU protein is engineered using biotechnological platforms, such as mammalian or bacterial expression systems, to produce functional uPA for research and therapeutic applications. It is typically generated by cloning the *PLAU* gene into expression vectors, followed by purification via affinity chromatography. Recombinant PLAU retains enzymatic activity and is utilized to study cancer metastasis, wound healing, and inflammatory diseases, where ECM remodeling and cell invasion are pivotal.
Clinically, recombinant PLAU has been explored for thrombolytic therapy to dissolve blood clots, though its systemic use is limited due to bleeding risks. Recent advances focus on engineering PLAU variants with improved specificity or reduced side effects. Additionally, PLAU's role in tumor progression has made it a target for anticancer therapies, with inhibitors and antibody-based strategies under investigation. Overall, recombinant PLAU serves as a vital tool for understanding proteolytic cascades and developing interventions for fibrosis, thrombosis, and metastatic diseases.
