Product Description |
Recombinant Human PLAU/uPA Protein (active form) is expressed from HEK293 with His tag at the C-Terminus.It contains Ser21-Leu431, which consists of two chains: Long chain A (Ser21-Phe177) and chain B (Ile179-Leu 431). The long chain A is further cleaved to yield a short chain A (Lys156-Phe 177) and N-Terminus fragment (Ser21-Lys155). |
Product Background |
Plasminogen activator, urokinase (uPA) is a secreted serine protease, cleaving the sequence Cys-Pro-Gly-Arg560-Val561-Val-Gly-Gly-Cys in plasminogen to form plasmin. Dysregulation of PLAU is often accompanied by various cancers and PLAU inhibition could suppress tumor growth. Collectively, PLAU is necessary for tumor progression and can be a diagnostic and prognostic biomarker in HNSCC. |
