  2019-08-27

  

  How does an increase in E2 affinity for the RING domain favor higher activity and polyubiquitination by the E2? Binding of the RING domain to the E2 positions the donor Ub in the E2~Ub conjugate in a closed complex [16], [17], [18] that increases the reactivity of the thioester [60]. A higher affini

  2019-08-27

  

  DUBs are involved in SIS3 regulation and DNA damage pathways and since, in cancer and different stress conditions all the proteins which regulate cell cycle and DNA damage/repair are either up/down regulated (Singh et al., 2013, Singh et al., 2011, Kumar and de Massy, 2010, Gupta et al., 2010), it

  2019-08-26

  

  In addition to PGC1α, transcriptional co-repressors such as NCOR and RIP140 participate in oxidative muscle remodeling induced by exercise, whereby reductions in their expression and the resulting de-repression of downstream TFs activates oxidative gene expression (Seth et al., 2007, Yamamoto et al.

  Initial investigations in the heart uncovered Epac as a positive regulator of myocyte hypertrophy [8], [9]. Concomitantly, Epac has been shown to regulate cardiac Ca homeostasis [8], [10], [11], [12], [13]. Ca is an essential second messenger in the cardiac physiology because its rhythmic variations

• The glycolytic pathway is a catabolic route

  2019-08-26

  

  The glycolytic pathway is a catabolic route that ends with the synthesis of pyruvate (Pyr). In Arabidopsis embryos, the conversion of phosphoenolpyruvate (PEP) to Pyr, catalyzed by pyruvate kinase (PK), is mainly located in the plastids [10], [11]. The preceding reaction is catalyzed by enolase (ENO

• The EGFR belongs to the ErbB family

  2019-08-26

  

  The EGFR belongs to the ErbB family of receptor tyrosine kinases (RTKs), comprised of four members: EGFR (ErbB1, HER1), HER2 (ErbB2), HER3 (ErbB3) and HER4 (ErbB4) [24]. HER receptors are activated by a group of epidermal growth factor (EGF) ligands and undergo homo- or hetero-dimerization during th

  APC/C Uses a Dynamic Cullin–RING Mechanism to Elongate Polyubiquitin Chains Human APC/C generates Lys11-linked poly-Ub chains through an entirely different mechanism, via the distinctive E2 enzyme, UBE2S 30, 31, 32. Although APC2 and APC11 are necessary and sufficient to activate UBE2S, the mecha

  2019-08-26

  

  General mechanism of NHEJ NHEJ is an amazingly versatile pathway that can select specific enzymes which bind to, process, and finally mediate the direct re-ligation of a wide range of DSBs including those that are complex, have incompatible ends, and contain aldose reductase inhibitors damages [

  Even though Et743 modification of DNA delayed the progress of the translocating enzyme significantly, it did not trap RecBCD on DNA, nor did it alter the activity of the enzyme significantly. Under catalytic conditions, no loss of enzyme activity was observed (Table 2), nor were stable unwinding int

  One possible explanation for differences in the binding ability of monomeric versus dimeric forms of DDR2 ECD to collagen could be that the monomeric form only binds to the primary GVMGFO site, whereas dimeric (and oligomeric) DDR2 ECD binds to additional sites on the collagen triple-helical molecul

  Interferon (IFN)-γ induces formation of a heterotetrameric, IFN-gamma-activated inhibitor of translation (GAIT) complex in human monocytic Apoptozole (Mazumder et al., 2003a, Sampath et al., 2004). The complex binds a bipartite stem-loop element in the 3′UTR of vascular endothelial growth factor (V

  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

  Besides the regulation of the stress responses, CRF and the urocortins have been implicated in drug addiction (Bruijnzeel and Gold, 2005, Sarnyai et al., 2001). For instance nicotine, the addictive substance of tobacco, can activate the HPA axis, just like any other stressor may do, although its imp

  The detection of galactomannan (GM), a polysaccharide that is released during Aspergillus growth, is a useful and reliable non-invasive diagnostic test for screening and management of aspergillosis and is often more sensitive than culture (Schelenz et al., 2015, Fisher et al., 2013).
