• The best characterized APC C substrates

  2021-07-30

  

  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

  2021-07-30

  

  Introduction Protein ubiquitination is a posttranslational modification that plays a major role in almost all cellular processes in eukaryotes (Hochstrasser, 2009; Komander & Rape, 2012). It involves the covalent attachment of ubiquitin (Ub) via its C-terminal glycine carboxylate to a primary amine

  Mammalian DGKs: current knowledge Despite our understanding of prokaryotic DGKs, our limited understanding of the structure of mammalian DGKs is a major gap in our knowledge. Importantly, major differences exist between prokaryotic and mammalian enzymes often revealing the fact that structural fe

  2021-07-30

  

  Introduction Formate dehydrogenase enzymes (FDHs) are a group of heterogeneous proteins that catalyse the reversible formate () oxidation to carbon dioxide () (Eq. (1)). These enzymes are classified in two families, one gathering the enzymes that hold no redox-active centres and another that includ

  2021-07-30

  

  N-methyl-d-aspartate (NMDA) receptor antagonists, such as MK-801 and phencyclidine, induce cognitive dysfunction in both mice and humans [18]. In addition, antipsychotic drugs ameliorate MK-801-induced cognitive dysfunction; therefore, the acute application of MK-801 can be used as an animal model o

  2021-07-30

  

  Nucleophosmin (NPM1), which also plays a role on the nuclear export of ribosomal proteins and subunits (Maggi et al., 2008), is also a relevant MYC target, presumably through an interaction with CRM1. Conversely, it has been recently reported that specific SINE compounds reduce the levels of MYC in

  We note that there are slight qualitative differences among the similar time-optimal protocols. We attribute this to the challenging nature of our PDE and ODE state constrained optimization problem. While our optimization algorithm was able to converge to local optima in each case, it is likely that

  During the first year of life, there was no interaction between cholesterol precursors and cholestanol, suggesting that cholesterol homeostasis was not yet developed. From the age of 1 year, cholesterol homeostasis could be considered intact. According to Fig. 1, cholesterol Zerumbone prevailed cho

  2021-07-29

  

  Oxidative stress is associated with elevated levels of intracellular reactive oxygen species (ROS) generation which then causes DNA damage and the death of cells (Miyata et al., 2017). Generation of ROS affects main signaling pathways in cells associated with tumorigenesis: mitogen activated protein

  Our finding that VEGF-A induced downregulation of EphB4 is VEGFR2 dependent (Fig. 4A) is not surprising because VEGFR2 is the primary signaling receptor of VEGF-A in EC [34]. However, our finding that VEGF-A induced upregulation of dll4 GSK2269557 is not inhibited by VEGFR2 inhibition suggests that

  Within the X1CX3PX5RX7 motif of several prokaryotic FGE substrates, the residues of X3, X5, and X7 are variably found as mixtures of alanine, glycine, threonine, or serine residues [26], [27]. The docked model of our identified HCTPRRP motif revealed that position X1 (H1) and position X7 (P7) were n

  While SCF E3 ligase activity was reconstituted with recombinant proteins two decades ago, the ability to probe APC/C was limited until recently because of its behemoth size. Human APC/C is a 1.2-MDa assembly comprised of 19 core subunits (one each of nine different APC subunits, and two each of five
