uPAR Protein, Human (Biotinylated, HEK293, His-Avi)
Based on 1 Customer Validation
The uPAR protein is a receptor for urokinase plasminogen activator and actively localizes and promotes plasmin formation. It mediates proteolysis-independent signaling activated by U-PA and undergoes negative feedback regulation. uPAR Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived uPAR protein, expressed by HEK293 , with C-Avi, C-His labeled tag.
- Species: Human
- Source: HEK293

Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Biological Activity
Description
The uPAR protein is a receptor for urokinase plasminogen activator and actively localizes and promotes plasmin formation. It mediates proteolysis-independent signaling activated by U-PA and undergoes negative feedback regulation. uPAR Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived uPAR protein, expressed by HEK293 , with C-Avi, C-His labeled tag.
Background
uPAR Protein functions as a receptor for urokinase plasminogen activator, actively participating in the localization and facilitation of plasmin formation. Additionally, it serves as a mediator of the proteolysis-independent signal transduction activation effects induced by U-PA. Subject to negative-feedback regulation by U-PA, uPAR Protein undergoes cleavage into an inactive form. Typically existing as a monomer, it interacts with various proteins, including MRC2, SRPX2 (via the UPAR/Ly6 domains), and FAP (seprase), with the latter interaction occurring at the cell surface of invadopodia membrane. Moreover, uPAR Protein engages in an interaction with SORL1, specifically through the N-terminal ectodomain, and this interaction has been associated with a decrease in PLAUR internalization. Notably, the formation of a ternary complex composed of PLAUR, PLAU (urokinase-type plasminogen activator), and SERPINE1 also involves an interaction with SORL1.

Product Properties
Lyophilized powder.
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Normally 8% trehalose is added as protectant before lyophilization.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O.
