Urokinase-type Plasminogen Activator (uPA) is a serine protease. The primary physiological substrate is plasminogen , which is an inactive form (zymogen) of the serine protease plasmin. Activation of plasmin triggers a proteolysis cascade that, depending on the physiological environment, participates in thrombolysis or extracellular matrix degradation. Restoration of cerebral blood flow by recombinant plasminogen activator (rtPA) with or without mechanical thrombectomy is considered the most effective therapy for rescuing brain tissue from ischaemic damage, but this requires advanced facilities and highly skilled professionals, entailing high costs, thus in resource-limited contexts urokinase plasminogen activator (uPA) is commonly used as … implicate the urokinase plasminogen activator (uPA)/uPA receptor (uPAR)/plasminogen system in the development of atherosclerosis and aneurysms.

Urokinase plasminogen activator upa

uPA is a serine protease with an extremely limited substrate specificity, cleaving the sequence Cys-Pro-Gly-Arg560-Val561-Val-Gly-Gly-Cys in plasminogen to form plasmin (1). uPA is a potent marker of invasion and metastasis in a variety of human cancers associated with breast, stomach, colon, bladder, ovary, brain, and endometrium (2). Urokinase-type plasminogen activator (EC: 3.4.21.73) Short name: U-plasminogen activator. Short name: uPA. Cleaved into the following 3 chains: Produced as an inactive single-chain protein (pro-uPA or sc-uPA), is processed into the active disulfide-linked two-chain form of PLAU/uPA by a proteolytic event mediated, at least, by TMPRSS4.

Urokinase Plasminogen Activator/Plasminogen Activator Inhibitor-1 Assay. Urokinase plasminogen activator (uPA) is a serine protease that specifically cleaves the proenzyme/zymogen plasminogen to form the active enzyme plasmin. The activation of plasmin triggers extracellular matrix degradation and modulates cellular adhesion, proliferation, and Matrigel penetration was drastically impaired by treatment of both cell lines with anti-urokinase plasminogen activator (uPa) antibodies blocking uPa-uPa receptor interaction; although to a lesser extent, tissue inhibitor of metalloprotease (TIMP)-1 was also active in reducing the invasive motility of only 8701-BC cells. Urokinase. Urokinase (also known as urokinase-type plasminogen activator, uPA) is a serine protease that catalyzes the conversion of plasminogen to plasmin. uPA interacts with a cell surface receptor known as the urokinase receptor (uPAR) to restrict plasminogen activation. Urokinase, also known as urokinase-type plasminogen activator (uPA), is a serine protease present in humans and other animals.

Urokinase plasminogen activator receptor (uPAR) is a glycosylphosphatidylinositol-anchored glycoprotein and cell surface receptor specific to the urokinase plasminogen activator (uPA) and is a promoter of plasmin activation. uPAR consists of three homologous domains, denoted by I, II, and III [147]. 2014-04-10 · Abcam’s Urokinase type Plasminogen Activator Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Urokinase type Plasminogen Activator (uPA) in plasma, serum, urine, milk, cell culture supernatants and tissue extracts.
