Crystal structure and cellular functions of uPAR dimer

Nature Communications, 2022
The structural basis for urokinase-type plasminogen activator receptor (uPAR) dimerization is not understood. Here, the authors solve the crystal structure of soluble uPAR dimers, identifying substantial structural changes compared to the monomer.

The Diagnostic Value of Soluble Urokinase Plasminogen Activator Receptor in Crimean-Congo Hemorrhagic Fever Disease in Emergency Department

Düzce Tıp Fakültesi Dergisi, 2021
Aim: The urokinase-type plasminogen activator (uPA) system consists of a protease, a receptor (urokinase-type plasminogen activator receptor, uPAR), and inhibitors that can be expressed on various cell types.

Elevated plasminogen activators are associated with hematoma progression in spontaneous intracerebral hemorrhage

Brain Hemorrhages, 2020
Endogenous fibrinolysis might lead to hematoma progression in spontaneous intracerebral hemorrhage (ICH). We studied plasma biomarkers of fibrinolysis and hemostasis in twenty-two patients with ICH and nine healthy controls (HC) in a single-center study.

Role of multidomain structure of urokinase in regulation of growth and remodeling of vessels [PDF]

The Ukrainian Biochemical Journal, 2013
Urokinase type plasminogen activator, or urokinase (uPA), is a multifunctional protein which plays special regulatory role in the vascular wall and can actuate the proteolytic and signal cascades.

Characterization of the murine plasminogen/urokinase‐type plasminogen‐activator system [PDF]

European Journal of Biochemistry, 1996
The murine plasminogen/urokinase‐type plasminogen‐activator (u‐PA) system was studied using purified proteins, plasma and endothelioma cells. Recombinant murine u‐PA was obtained as a single‐chain molecule of 45 kDa which was converted to two‐chain u‐PA with plasmin by cleavage of the Lys159‐Ile1 60 peptide bond.

Leukocyte- and endothelial-derived microparticles: a circulating source for fibrinolysis

Haematologica, 2012
Background We recently assigned a new fibrinolytic function to cell-derived microparticles in vitro. In this study we explored the relevance of this novel property of microparticles to the in vivo situation.Design and Methods Circulating microparticles ...

Proteolytic enzyme and adiponectin receptors as potential targets for COVID-19 therapy

Кардиоваскулярная терапия и профилактика, 2021
The coronavirus disease 2019 (COVID-19) pandemic requires not only the creation of vaccines to prevent the spread of the disease, but also the development of novel drugs aimed at reducing viral load, suppressing an excessive immune response and ...

Tyrosine phosphorylation of human urokinase‐ type plasminogen activator [PDF]

FEBS Letters, 1991
Immunoblatting analysis of purified human urokinase plasminogen activator (u‐PA), gives a positive signal when reacted with anti‐phosphotyrosine monoclonal antibodies (MoAb anti P‐Tyr); competition with α‐phospha‐DL‐tyrosine (P‐Tyr) but not α‐phosphia‐DL‐threonine or serine (P‐Treo, P‐Ser) completely suppresses this signal.

Multiparity upregulates placental plasminogen and urokinase‐type plasminogen activator

American Journal of Reproductive Immunology, 2017
ProblemMultiparity increased the number of trophoblast cells in decidua of both low and high fetal loss mouse models. However, they differ in fetal survival rate and maternal thymocyte subpopulations, suggesting that trophoblast invasiveness is not equivalent.

Proenzyme to urokinase‐type plasminogen activator in the mouse in vivo [PDF]

FEBS Letters, 1985
We have investigated whether urokinase‐type plasminogen activator (u‐PA) is present in the mouse in vivo as the proenzyme or as the active enzyme. u‐PA in extracts of various murine tissues was of a one‐polypeptide chain form with an electrophoretic mobility indistinguishable from purified proenzyme (pro‐u‐PA), as demonstrated by SDS‐polyacrylamide gel
