Extraction-separation of Eu(III) and Th(IV) ions from nitrate media into the ionic liquid 1-hexyl-3-methylimidazolium hexafluorophosphate by a phosphorylated salen extractant, bis(chlorophosphoryle)decahydro-2,4-di(2-hydroxyphenyl)benzo[d][1,3,6]oxadiazepine (DPO), is investigated. It is found that Eu(III) ions are extracted via a solvation mechanism, and the extraction of Th(IV) i...

This article discloses a study on chiral bis-phosphorylated-helical ligand in the palladium-catalyzed Tsuji-Trost allylation. The use of 2,15-bisphosphinite-[6]-helicenes revealed remarkable effect, which (R) and (S) isomeric products can be selectively formed as direct function amount introduced. Investigation organometallic species involved through 31P NMR spectroscopic analysis model complex...

Following ligand stimulation, several Toll-like receptors (TLRs) are phosphorylated at tyrosine residues in their intracellular domains. However, the precise chain of events leading to tyrosine-phosphorylation-dependent TLR-mediated cytokine secretion has not been defined. We focused on elaborating the signaling pathway of tyrosine-phosphorylated TLR2. We demonstrated that two tyrosine residues...

Plant lipid transfer proteins are a large family that can be found in all land plants. They have hydrophobic cavity allows them to harbor lipids and facilitates their traffic between membranes. However, humans, this plant protein is responsible for the main food allergies Mediterranean area. Nevertheless, not only itself but also its ligand relevant allergic sensitization. The aim of present wo...

Diterpene glucoside fusicoccin A (FC-A) is a phytotoxic fungal metabolite that stabilizes the interactions between 14-3-3 protein and phosphorylated ligand protein. 14-3-3-mediated binding central to regulation of serine/threonine kinase signaling pathway in all eukaryotic cells essential for controlling numerous biological processes. Thus, fusicoccins could serve as robust platform developing ...

The activity of calmodulin (CaM) is modulated not only by oscillations in the cytosolic concentration of free Ca(2+), but also by its phosphorylation status. In the present study, the role of tyrosine-phosphorylated CaM [P-(Tyr)-CaM] on the regulation of the epidermal growth factor receptor (EGFR) has been examined using in vitro assay systems. We show that phosphorylation of CaM by rat liver s...

PURPOSE The purpose of this research was to determine whether estrogen receptor alpha specifically phosphorylated at Ser(118) is associated with clinical outcome in primary breast tumors from estrogen receptor-positive and node-negative breast cancer patients. EXPERIMENTAL DESIGN Estrogen receptor alpha specifically phosphorylated at Ser(118) was determined by immunohistochemistry in 117 prim...

In this tutorial, we exemplify automated modeling for a small example system. Assume a receptor R that can bind the ligand L. We consider one additional binding site which undergoes autophosphorylation and is influenced by the state of the ligand binding site. Therefore, a graded interaction [1] is present between the processes of ligand binding and autophosphorylation. An effector E can bind t...
