uPAR (human)

Overview
uPAR Acts as a receptor for urokinase plasminogen activator. Plays a role in localizing and promoting plasmin formation. Mediates the proteolysis-independent signal transduction activation effects of U-PA. It is subject to negative-feedback regulation by U-PA which cleaves it into an inactive form. Monomer (Probable). Interacts with MRC2. Interacts (via the UPAR/Ly6 domains) with SRPX2. Expressed in neurons of the rolandic area of the brain. Expressed in the brain. 3 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
