  2021-03-08

  

  The Ewing sarcoma breakpoint region 1 gene (EWSR1) is a partner in a large, diverse range of mesenchymal (and some nonmesenchymal) tumors (Tables 1 and 2). As the 5′ partner, EWSR1 is able to fuse with an array of genes. These fusions can generate genetically different but phenotypically identical n

  The requirement for two distinct signalling pathways for cAMP-induced growth arrest likely represents an important mechanism allowing VSMC to finely modulate their cellular responses to cAMP-elevating stimuli. Our data demonstrates for the first time that activation of both pathways in VSMC results

  In SLO-permeabilized human sperm, the AR elicited by calcium, persistently active Arf6 [41] and Rab3A, 8-pCPT-2′-O-Me-cAMP [8], diacylglycerol and a non-hydrolyzable analog [35], is sensitive to the PLC blocker U73122. Furthermore, 8-pCPT-2′-O-Me-cAMP elicits a calcium signal in non-permeabilized sp

  2021-03-08

  

  In addition to providing substantial insight into substrate recognition, structural studies have revealed important details about mechanisms of glycosylation and HCF-1 cleavage [28,30,33]. Activation of the nucleotide-sugar is accomplished through interactions of the β-phosphate with the N-terminus

  LVDP values of ~80% at the end of reperfusion. L-NAME treatment did not modify the contractility detected in ischemic control hearts but annulled the actions of BZ acquiring LVDP values up to 40% (Fig. 4 A). A similar pattern was observed when +dP/dtmax was analysed (Fig. 4 B). LVEDP, as an index o

  2021-03-08

  

  TraM is one of two transfer proteins from pIP501 T4SS that have structural similarity to the A. tumefaciens VirB8 protein (Fercher et al., 2016, Goessweiner-Mohr et al., 2013), a central member of the inner membrane complex (Bailey et al., 2006, Guglielmini et al., 2014, Trokter et al., 2014). VirB8

  According to the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB, 1992), peptidases are divided into two classes, namely exopeptidases and endopeptidases, based on their actions on substrates and their active sites, respectively. Endopeptidases inclu

  The best-characterized APC/C substrates are recruited via various linear motifs (e.g., D boxes, KEN boxes, and ABBA motifs) that serve as degrons, binding to distinct regions of the β-propeller domain of a coactivator (Figure 1, Figure 3B) (reviewed in [44]). In addition, D boxes also simultaneously

  Introduction Cholesterol plays a pivotal role as a constituent of biological membranes and as a precursor for vitamins, hormones and bile acids. Accordingly, its production, distribution, and elimination must be tightly regulated at the cellular and organismal level. Accordingly, dysregulated chole

  Introduction The ubiquitination status of a target protein is achieved via a delicate balance between two opposing forces: ubiquitin E3 ligases and DUBs. It has been postulated that the majority of proteins in a cell are regulated and modified by ubiquitin at some point (Hershko and Ciechanover,

  2021-03-05

  

  Primases are classified into two major groups: first, the DnaG primases, found in bacteria and bacteriophages, and second, the archaeoeukaryotic primases. Remarkably, bacterial and archaeoeukaryotic primases have no structural similarity and, presumably, evolved independently (Leipe et al., 1999).

  Introduction DNA-dependent protein kinase (DNA-PK) is a multicomponent serine/threonine protein kinase and considered a member of the phosphatidylinositol (PI) 3-kinase related kinase (PIKK family). This enzyme plays a critical role in the repair of mammalian DNA double strand breaks (DSBs) throu

  Autophagy alterations are frequently reported as one of the pathological mechanisms contributing to neurodegenerative diseases, due to incomplete removal of protein what is c2 in the brain [30,41].

  In summary, our data show a novel mechanism: CPD-mediated autoprocessing of C difficile toxins regulates their proinflammatory activities. Thus, our study provides a new understanding of the molecular mechanisms of the pathogenesis of C difficile toxins and insights into designing new therapeutics a
