Abstract Vascular endothelial growth factor‐C (VEGF‐C) binds to receptor vascular endothelial growth factor receptor‐3 (VEGFR‐3) expressed on lymphatic endothelial and melanoma cells. Binding of VEGF‐C to VEGFR‐3 enhances receptor phosphorylation that activates mitogen‐activated protein kinase (MAP‐K) and phosphatidylinositol‐3‐kinase (PI3K).

RNA mimicry by the fap7 adenylate kinase in ribosome biogenesis.
During biogenesis of the 40S and 60S ribosomal subunits, the pre-40S particles are exported to the cytoplasm prior to final cleavage of the 20S pre-rRNA to mature 18S rRNA. Amongst the factors involved in this maturation step, Fap7 is unusual, as it both

Cyclic AMP metabolism and adenylate cyclase concentration in patients with advanced hepatic cirrhosis [PDF]
Glucagon was tested for its effect on plasma adenosine 3′,5′-cyclic monophosphate (cyclic AMP), insulin, and glucose in healthy subjects and in patients with advanced cirrhosis of the liver. In the normal subjects, intravenous infusion of glucagon caused

Abstract Objectives Acute cerebral ischemia is characterized by several pathological processes evolving during time, which contribute to the final tissue damage. Secondary processes, such as prolonged inflammatory response, impaired mitochondrial function and oxidative stress, are responsible for the progression of brain injury to the peri‐infarct area,

High and stable ATP levels prevent aberrant intracellular protein aggregation in yeast
Adenosine triphosphate (ATP) at millimolar levels has recently been implicated in the solubilization of cellular proteins. However, the significance of this high ATP level under physiological conditions and the mechanisms that maintain ATP remain unclear.

A guanosine 5′-triphosphate-dependent protein kinase is localized in the outer envelope membrane of pea chloroplasts [PDF]
A guanosine 5-triphosphate (GTP)-dependent protein kinase was detected in preparations of outer chloroplast envelope membranes of pea (Pisum sativum L.) chloroplasts.

Coupled ATPase-adenylate kinase activity in ABC transporters
ATP-binding cassette (ABC) transporters hydrolyse ATP to transport molecules across the cell membrane. Here Vogelet al. show that the ABC exporter MsBA can couple ATP hydrolyse to an adenylate kinase activity that seems to be predominant at low ATP ...

Molecular and functional characterization of a Trypanosoma cruzi nuclear adenylate kinase isoform. [PDF]
Trypanosoma cruzi, the etiological agent of Chagas' disease, is an early divergent eukaryote in which control of gene expression relies mainly in post-transcriptional mechanisms.

The ever unfolding story of cAMP signaling in trypanosomatids: vive la difference! [PDF]
Kinetoplastids are unicellular, eukaryotic, flagellated protozoans containing the eponymous kinetoplast. Within this order, the family of trypanosomatids are responsible for some of the most serious human diseases, including Chagas disease (Trypanosoma ...

Subnanometre enzyme mechanics probed by single-molecule force spectroscopy
Adenylate kinase catalyses the interconversion of adenosine phosphates, and plays a crucial role in maintaining cellular energy homeostasis. Here, the authors use single molecule optical tweezers to understand how the enzyme’s conformation dynamics ...
