  2021-02-10

  

  Ubiquitin-activating enzyme activates ubiquitin by a three-step process with ATP as a cofactor (Chen et al., 2011, Haas and Rose, 1982, Haas et al., 1982). We demonstrated that ATP is required for mRFP-Ub–E1 formation under non-reducing conditions (Fig. 2A). A time course of radioactive ATP producti

  Common features of TdT, pol μ and pol λ TdT, pol μ and pol λ remain in a closed conformation throughout their catalytic cycle, contrary to pol β [24•, 53, 54•]. One possible explanation for this observation is that they have traded fidelity (which requires open-to-closed transition) for a very ti

  The photocleaving properties of 1 were studied by performing ΦX174 photocleavage assays. Light irradiation of the mixtures of increasing amounts of 1 with supercoiled DNA caused>90% supercoiled form relaxation and approximately 5% of linearization for the higher concentrations of 1 (1:10bp and 1:2bp

  2021-02-10

  

  Classical DHFR inhibitors such as methotrexate (MTX) bind tightly to the enzyme and possess adequate clinical pharmacokinetics. MTX bind to the DHFR binding site through the formation of hydrogen bonds with Asn64, Lys68, Arg28, Arg70, Val115 and Ile7 amino Etoposide residues as well as hydrophobic

  2021-02-10

  

  Our data indicate that the ability of these promiscuous kinases to bind chemically diverse inhibitors is defined by the hydrophobic pocket formed by the activation loop, which is only accessible in the DFG-Asp-out conformation. Inhibitors do not artificially induce the DFG-Asp-out conformation as wa

  2021-02-10

  

  Introduction Tumor necrosis factor (TNF) is a pro-inflammatory mediator with the capacity to induce apoptosis (Benderska et al., 2012). Recent reports have shown that TNF might trigger cell death, at least in part, by directly affecting the reorganization of the β(1,3)-d-glucan synthase cytoskeleto

  In the course of our program, which was aimed at developing CRTH2 antagonists for the treatment of allergic diseases, we have been pursuing a new class of potent and selective CRTH2 antagonist lead based on the structures of CRTH2 antagonists known to date (, , ). Using a fused 6–6-membered ring sys

  The acetylcholinesterasic activity of exposed animals, after treatment with diverse concentrations of uranium and following distinct recovery periods, remained unaltered for all species. This finding suggests that uranium, in spite of being a water-soluble metal, does not exert any effect on the sel

  2021-02-09

  

  Astrocytes play a key role in the brain, as these cells are involved in fluid, ion, pH, and neurotransmitter homeostasis, synapse function, energy and metabolism and blood-brain barrier (BBB) maintenance (Sofroniew and Vinters, 2010). PA is able to activate different damaging responses in astrocytes

  The reduction of the calcium response to AVP could be also due to a PKA-mediated effect of desensitization of IP3R, as described in rat megakaryocytes [41]. Furthermore, PKA activation inhibits intracellular Ca release in mouse pancreatic acinar cells [42] or in rat cerebellum [43]. The phosphorylat

  Further modifications on the 8-position of compound led to compound 4 (8-pCPT-2′--Me-cAMP, a.k.a. 007, ), which is a potent (half-maximal activation of EPAC1 at 2.2µM) and selective (about 100-fold EPAC/PKA selectivity) EPAC agonist. Since the discovery of compound , it has been widely used as a po
