  2020-04-20

  

  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

  Substituents at the C11 position — An oxygen-containing substituent at the C11 position also affects the catalytic activity of Δ1-KSTDs. The Δ1-KSTDs from the Gram-positive bacteria R. equi [29], N. simplex ATCC 6946 and IFO 12069 [48,49,52], and R. rhodochrous IFO 3338 [27] were able to 1(2)-dehydr

  Unlike CRM1, exportins Cse1 and Xpot lack a C-extension and instead rely primarily on changes in HEAT-repeat conformation and direct Ran-cargo contacts to ensure low cargo-binding affinity in the cytosol and cooperative assembly of the exportin/Ran/cargo complex in the nucleus (Cook et al., 2005, Co

  Third trimester – crossing the threshold to immunocompetence Summary Regrettably, studies on the fetal immune system have yet to yield practical results. While it is becoming apparent that the fetal immune response plays a role in determining the outcome of congenital CMV infection, we still l

  2020-04-17

  

  Mammalian TTNPB have two distinct DNA repair pathways for DSBs, NHEJ and HR. Our data are consistent with the suggestion that the DNA–PK-mediated NHEJ pathway recognizes DSBs faster than the HR pathway and acts before the activation of the DNA damage S-phase checkpoint. The activation of NHEJ by DN

  Contributors Acknowledgements Introduction Pemphigus disorders are characterized by autoantibodies binding to desmosomes between epidermal cells, resulting in the loss of cell to cell adhesion and blister formation. In pemphigus foliaceus, autoantibodies predominantly bind to desmoglein 1,

  Water solubility experimental data of 24 water + hydrocarbon mixtures are used to find a general correlation for CPA model parameters. Finally, the model is benchmarked against three complex water solubility data set (Athabasca bitumen + water mixtures) from the literature [25], [26]. The model reli

  Chk 1 and Chk 2 mediated signaling act as a barrier to tumorigenesis It was hypothesized recently that early events during tumorigenesis, such as the overexpression of oncogenes, lead to a DNA-damage response which, in turn halts tumor progression [44], [45], [46]. The DNA-damage response is prop

  In addition to the classic nuclear genomic action, estrogens have been found to induce rapid effects occurring within minutes following administration. These effects are mediated through a subpopulation of estrogen receptors associated with the plasma membrane, a process usually termed “membrane-i

  Together, the data suggests that more work needs to be done to establish the role of PARP inhibitors in Ewing sarcoma. As a single agent, there is some activity in Ewing sarcoma cell lines and a highly statistically significant relationship between olaparib sensitivity and EWS–FLI1 expression. Howev

  Methods Results First, we compared Aβ plaque number, Aβ concentration, and neurobehavior functions between naive APP/PS1 and APP/PS1xEP1−/− mice. Significantly lower Aβ burden in APP/PS1xEP1−/− mice was evidenced by fewer plaques in the hippocampal area and a lower concentration of soluble Aβ42

  Conclusions We can conclude that Arg293 is important but not indispensable for MeGlcA recognition by EcXyn30A since the R293A variant still retains activity and preference for MeGlcA-substituted substrates. The substrate specificity of GH30_8 glucuronoxylanases is most probably determined by an o

  Results Discussion The ubiquitin system has in recent years become an exciting area for drug discovery (Cohen and Tcherpakov, 2010), as multiple enzymatic steps within the ubiquitylation process are druggable. The potential of targeting the ubiquitin-proteasome pathway was first demonstrated i

  Transcription can also be impaired by lesions in the template DNA strand, which may lead to stalling of RNA polymerase (RNAP) or to transcriptional mutagenesis, thus producing mutant RNAs and proteins [[3], [4], [5], [6], [7]]. At the same time, RNAP can act as a sensor for DNA lesions, by attractin

  In most cases, patients will not present immediately after SM exposure because SM-induced clinical symptoms typically occur after a latency period of several hours [8], [9], [10]. When they do present, the detection of free, unbound alkylating agent is highly unlikely. For this reason, available rap
