  An even more striking difference is observed when comparing active site residues, which are evolutionarily very well conserved in other soluble PPases 18, 19. In 31 known PPase sequences, 13 functionally important active site residues are conserved in all sequences, but only two of them (D70 and D97

  Several main strategies for targeting E3s described in the literature include: in vitro screening using functional assays [86]; computer programs for predicting potential druggable pockets, including those at protein-protein interfaces, and subsequent docking-based in silico ligand screening [87]; f

  2019-08-06

  

  The combination of brequinar and 5-fluorouracil (5-FU) has been evaluated to assess whether brequinar-induced uridine depletion would improve 5-FU activity. In cells, 5-FU is metabolized into FdUMP and inhibits thymidylate synthetase, which catalyzes the formation of thymidine monophosphate from deo

  Anti-inflammatory effects of MTX In addition to cytotoxic and cytostatic effects, the anti-inflammatory activity of MTX was also described by several studies. Inhibition of ATIC by MTX has been found to result in the accumulation of 5-aminoimidazole-4-carboxamide-1-β-d-ribofuranosyl 5′-monophosph

  P. falciparum DHFR-TS is a particularly important enzyme, because it is from the protozoan species that is associated with most malaria infections. Since this enzyme is responsible for catalyzing sequential reactions in the thymidylate cycle, its inhibition slows malarial dTMP production and therefo

  Introduction PGE2 is a major mediator present at sites of inflammation [1]. It is well established that PGE2 contributes to the localized and systemic symptoms of inflammation. A key study by Portanova et al. [2] demonstrated that anti-PGE2 Wiskostatin were able to reverse the swelling and pain in

  2019-08-06

  

  The discoidin domain receptors, DDR1 and DDR2, are receptor tyrosine kinases (RTKs) that are stimulated by collagen in the extracellular matrix (ECM). Unlike most other RTKs, they form ligand-independent stable dimers that are non-covalently linked. This ECM activation induces receptor phosphorylati

  The in vitro enantioselective metabolism of pesticides has been investigated by employing human liver microsomes, which are a reliable resource to perform MCL enantioselective risk assessment in humans (Carrão et al., 2019; de Albuquerque et al., 2018, 2016; Yao et al., 2016).

  RING dimerization RING-type domains are found in many different structural contexts. While many exist as single-chain GANT61 (Fig. 3A), a notable feature of RING-type E3s is their tendency to form homodimers and heterodimers (Fig. 3C–F). Homodimeric RING-type E3s include cIAP, RNF4, BIRC7 (shown

  Programmed cellular death or apoptosis is a process genetically controlled that plays an important role in cellular homeostasis, being an important defense mechanism to remove cells that have been infected, damaged or mutated (Smith and Smith, 2012, Wlodkowic et al., 2011). Nevertheless, apoptosis s

  Lately, using receptor TM peptides, BiFC and PLA experiments, we have also obtained experimental evidence for the tetrameric structure of A1R–D1R, which explains the canonical interaction on Gi and Gs, respectively (Fig. 2). We have demonstrated for the first time the presence of this heterotetramer
