PLAU (plasminogen activator, urokinase) is a plasminogen activator, which is produced by renal and other cells. It is a serine protease, and acts as a ligand for UPAR (urokinase-type plasminogen receptor). This protein has a wide range of tissue expression.
Urokinase-type plasminogen activator precursor recombinant protein epitope signature tag (PrEST)
PLAU (plasminogen activator, urokinase), post-activation, cleaves plasminogen to produce plasmin, which then degrades multiple constituents of the ECM (extracellular matrix). Along with UPAR and protease inhibitor PAI, it makes the UPA system, which is essential for controlled focal proteolysis and cell migration and adhesion. Therefore, it is also implicated in tumorigenesis, and is linked to gastric cancer (GC). The expression level of this system is also linked to the peritoneal metastasis of GC. In idiopathic membranous nephropathy, variants of this gene are linked with mortality and ESRD (end stage renal disease). Over-expression of this gene is linked to poor prognosis of pancreatic ductal adenocarcinoma (PDAC). It facilitates the stemness of cancer cells by interacting with LIM homeobox-2 (Lhx2), homeobox transcription factor A5 (HOXA5) and Hey proteins. Studies in Northern Chinese Han population suggest SNPs (single nucleotide polymorphisms) in this gene are linked with the occurrence of oral tongue squamous cell carcinoma (OSCC).
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.
Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
