  2021-04-08

  

  How does APC/C recognize its substrates and catalyze their ubiquitylation? How are the outcomes and timing of these activities regulated? These questions have driven a decade of structural studies that begin to explain how APC/C interacts with coactivators, substrates, and E2s, and how these interac

  Although our knowledge of the biochemical and biological functions of E3 ubiquitin ligases has increased in B-cell malignancies, a deeper characterization of cell-context dependent substrate regulation and biological relevance is needed. The recent approval of a general proteasome inhibitor, VELCADE

  2021-04-07

  

  Interest in DGKs increased as it became clear that not only are they important for lipid homeostasis, they serve to modulate the relative levels of diacylglycerol (DAG) and phosphatidic Adenosine (PtdOH) that play critical roles in a variety of signaling pathways (Eichmann and Lass, 2015; Liu et al.

  Extracellular uridine can be transported across the cell membrane to enter the nucleotide salvage pathway. A colon cancer cell line supplemented with uridine was capable of growing normally in the presence of 1 μM brequinar (Peters et al., 1992). The supplemented uridine may be transported into the

  2021-04-07

  

  An increasing body of evidence demonstrates that MXC can cause neurobehavioral and neuropathological alterations [7]. In the brain, there are several steroidogenic enzymes, which are responsible for neurosteroid production. Neurosteroids are subsets of steroids that rapidly change neuronal excitabil

  2021-04-07

  

  Calcium dependence of CaM/target interaction was analyzed using a titration matrix in which both Ca2+ and CaM concentrations were changed. This gave us access to different parameters characterizing the interaction and namely to the number of bound Ca2+ required for the interaction to occur. Our app

  2021-04-07

  

  This review focuses on the atomic basis of CRM1-mediated nuclear export. There are now 27 crystal structures of CRM1 in the Protein Data Bank (PDB) (www.rcsb.org) [64]. Collectively, this large body of work explains various aspects of CRM1 function. Here we summarize the structure–function studies t

  Recent data obtained with etifoxine suggest that facilitation of GABAergic inhibition may be also associated with an indirect mechanism implying activation of the peripheral benzodiazepine receptor with a subsequent increase in neurosteroid production (Schlichter et al., 2000, Verleye et al., 2005).

  Heterozygous SERT knockout showed an intermediate level of FPS in Experiment 1, but normal FPS in Experiment 4, Experiment 5. Apparently, high redundancy exists in the involvement of SERT in normal fear acquisition, as availability of only 60% of normal SERT levels (Homberg et al., 2007a) is still s

  In the preclinical evaluation of CRF1 receptor antagonists, effects were mainly focused on the regulation of hyperactivated HPA axis and the modulation of anxiety or depressive-like behaviors in CRF challenge [16], [17], [18] or stress models [16], [19], [20]. However, it remains to be concluded whe

  Introduction Safety-critical systems are defined as those systems where failure could result in the loss of life or injury to people, damage to equipment or to the environment [9]. Safety standards, e.g., [41], [17], [18], [6], [38], expect appropriate safety analysis tasks to be integrated within

  Endothelins (ETs) are peptides expressed in both the peripheral and the central nervous systems, which can contribute to sensory changes seen in animal models of inflammatory, cancer and neuropathic pain [10], [11]. All three mammalian isoforms (ET-1, ET-2 and ET-3) activate specific G protein-coupl

  In the literature, we can find two different modes of action for estrogens: Firstly there is the commonly accepted genomic pathway. Estrogens pass the cell membrane due to their lipophilic character via diffusion and bind to estrogen receptors (ERs) in the cytoplasm. After binding a dimerization of

  OxLDL down-regulates eNOS and up-regulates iNOS, thereby augmenting the formation of NO and protein S-nitrosylation in human endothelial N1-Methylpseudouridine synthesis [26]. Importantly, iNOS-mediated S-nitrosylation plays an increasingly significant role in cardiovascular diseases [34]. For exam
