  In contrast, crystal structures of the oxyester-linked Ubc13 and UbcH5b conjugates (Eddins et al., 2006, Sakata et al., 2010), and the NMR structure of the disulfide-linked UbcH8 conjugate (Serniwka & Shaw, 2009), revealed distinct open conformations (Fig. 10.3). In part, differences in the position

  2021-01-13

  

  To explore the mechanism behind differential activation kinetics, Marcott et al. (2018) manipulate local dopamine dynamics. They show that differences in dopamine concentrations are not responsible for different D2R activation kinetics, since D2-IPSCs reach similar amplitudes at different rates in N

• DNA bound Ku proteins recruit DNA PKcs and thereby

  2021-01-13

  

  DNA-bound Ku proteins recruit DNA-PKcs; and thereby translocate into the duplex by one helical turn, leaving DNA-PKcs near the DNA terminus to assist in tethering the broken ends together [25]. In addition to keeping the DSBs in close proximity, DNA-PKcs may prevent exonucleolytic degradation of the

  2021-01-13

  

  Sp family protein has been regarded as the housekeeping gene and is ubiquitously expressed. Although Sp family expression is regulated with some stimuli [17], [20], the total Sp family protein levels are not changed in most cases, as observed in our present study (Fig. 4). Constitutive binding of th

  2021-01-13

  

  Proteolysis by CPs is crucially important for cereal seed development and germination. However, these enzymes must be tightly controlled. Pre-harvest sprouting is a phenomenon in which the control of CPs is disrupted. This disruption manifests in the premature synthesis and activation of CPs, leadin

  2021-01-13

  

  IAA-94-sensitive Cl channels were shown to mediate cardioprotection due to IPC (Diaz et al., 1999) and cyclosporine A (Diaz et al., 2013). CLIC-like channel activity was also observed in cardiac mitoplast (Misak et al., 2013) but the molecular identity of these intracellular Cl channels and their pr

  2021-01-13

  

  Our work raises the question of how a mechanism for control of developmental potency based on TEs might have evolved. Active TEs are under acute surveillance by cellular pathways that minimize transposition, including by Kap1 (Rowe et al., 2010). In part because of this, and in part because of a los

  2021-01-13

  

  Another milestone in the field is the de novo discovery of EPAC2 and EPAC1 specific inhibitors through fluorescence-based HTS assays. Due to the excellent EPAC/PKA selectivity of Triacetyl Resveratrol , it has been widely applied as a useful chemical probe to discriminate EPAC related signaling pat

  Oxysterols as Key Players in Metabolic Syndrome? Obesity and sedentary lifestyle are on the rise and pose serious threats to people's health and wellbeing. Obesity is often associated with other pathologies and is one of the criteria included in the definition of metabolic syndrome (MetS) (see Gl

• Multi subunit RING type E ligases

  2021-01-12

  

  Multi-subunit RING-type E3 ligases are exemplified by the CULLIN-RING-ligase (CRL) and the anaphase-promoting complex/cyclosome (APC/C) [19]. CRLs constitute the biggest family of other multi-component E3 ligases. These consist of a cullin scaffold protein (CULLIN 1, 2, 3, 4A, 4B, 5, 7), a substrate

• DNA methylation is associated with transcriptional silencing

  2021-01-12

  

  DNA methylation is associated with transcriptional silencing of tumor suppressors or other genes important for normal cellular function and plays an important role in the development of cancer and other diseases (such as breast and colorectal cancers) [19]. DNA methyltransferases (MTases) are a fami

  2021-01-12

  

  Since the initial identification of DNA ligase inhibitors by a structure-based approach [[18], [26]], there have been several reports describing LigI inhibitors using computer modelling and derivatives of the original DNA ligase inhibitors [[49], [50], [51]]. While these studies have shown that the

  Preparation of the regioisomeric pyridooxazepinones 10 and 11 was accomplished utilizing the synthetic sequence depicted in Scheme 3. Amide coupling of 63 and Cdk2/Cyclin Inhibitory Peptide I chloride 64 afforded amide 65. Removal of the alcohol protecting group, followed by base catalyzed cyclizat

  Resveratrol is a phytoalexin that occurs in relatively large amounts in peanut, berries, grapes, and red wine (Soleas et al., 2001). A recent study showed that resveratrol prevents social deficit in an animal model of autism, indicating its potential for possible therapeutic use in children with aut

  2021-01-12

  

  The identification of a functional leucine-rich NES mediating 8E7 nuclear export led us to analyze the interaction between 8E7 and CRM1 nuclear export receptor. HeLa cell lysates containing EGFP-8E7, EGFP–8cE7, EGFP-16E7–NES (as a positive control), or EGFP (as a negative control) were incubated wit
