[Cdna Cloning and Sequencing of Human Urokinase Receptor].

Human urokinase receptor (uPAR), a 55 kD glycoprotein linked to the cell membrane by a glycosylphosphatidylinositol anchor, plays a central role in cell migration and tissue remodeling. The human uPAR cDNA was cloned from a highly metastatic human lung giant cell line PG by RT-PCR and then subcloned into pGEM-T vector and sequenced. The data indicate that there are three bases substitution (705, 746, 755) which subsequently leads to two amino acid mutation (249, 252) compared to that of previously reported. The cDNA sequence of uPAR was registered in GenBank with accession number AF257789.
