  Most reported binding data are obtained by performing heterologous competition binding experiments and expressing the results as relative binding affinity (RBA). The constructed binding curves should theoretically be sigmoidal in shape with a Hill slope value of one, for a single ligand binding to

  Materials and methods Results Discussion It has been demonstrated that up-regulation of EPHB4 impaired trophoblast migration and invasion during placentation, which may contribute to the pathogenesis of preeclampsia [11], [24]. However, the upstream regulating mechanism of EPHB4 expression

  A set of small molecule LigI inhibitors were identified through an in silico structure-based screen, using the atomic resolution structure of LigI complexed with nicked DNA [[18], [26]]. This screen yielded inhibitors that were selective for LigI (L82), inhibited both LigI and LigIII (L67) and inhib

  VHb expression in recombinant E. coli expressing P4H improved Hyp production, presumably by enhancing oxygen transfer. VHb expression contributed to improving growth and extending the period of exponential growth in both shaker flask culture and bioreactor fermentation. A similar phenomenon was also

  Diverse functions of ERK pathway Same as the other MAPK cascades, the ERK pathway is activated by several extracellular stimuli and different internal routes. ERK vitally tunes the function of various substrates in all cellular components; the nucleus, cytoplasm, membranes and the cytoskeleton. E

  Our study provides proof of principle for dimerizing two different E3 ligases as a novel approach to inducing one ligase to degrade the other one. The outcome of ‘ligase versus ligase’ PROTAC-mediated activity might be unpredictable a priori, but could reveal a new mechanism for proximity-mediated h

  Introduction Structure of the Ku heterodimer associated to DNA The atomic structure of the Ku heterodimer, alone and bound to a small DNA fragment, was recently determined (Walker et al., 2001) and has significantly improved our understanding of DNA recognition by DNA-PK holoenzyme (Fig. 3). B

  In the gel shown in Figure 8, at early time-points, 14% of the input dsDNA is converted to these intermediate species. These persist in the gel to later times, with approximately 50% of these being unwound. This unwinding occurs at a considerably slower rate and is due to that fraction of the popula

  An increasing body of evidence demonstrates that MXC can cause neurobehavioral and neuropathological alterations [7]. In the brain, there are several steroidogenic enzymes, which are responsible for neurosteroid production. Neurosteroids are subsets of steroids that rapidly change neuronal excitabil

  In this report we describe studies of the effects of peroxisome proliferator-activated receptor γ (PPARγ) and acyl-CoA synthetase (ACSL1) on palmitate-induced ER stress in the human cardiomyocyte-like cell line AC16 [22], which was derived from adult ventricular heart tissue. PPARγ is a nuclear rece

  Introduction O6-Methylguanine-DNA methyltransferase (MGMT) is a DNA-repair enzyme that specifically transfers alkyl adducts from the O6 position of guanine to the cysteine residue (Cys145) in its active site. In cancer cells, this ability of MGMT disrupts the cytotoxic actions of alkylating antic

  Instead of receptor interaction or GT activity, we focused on the CPD and autoprocessing. The CPDs from the 2 toxins are highly homologous: each cysteine protease targets an intramolecular substrate and mediates InsP6-induced autoprocessing to release the GTD into host cytosol.40, 41 However, TcdB i

  2019-10-02

  

  CDK6 lacks DNA-binding domains and nuclear localization sequences, and therefore will probably be transported to the nucleus by a ‘piggy-back’ mechanism and needs to contact its specific sites indirectly through DNA-binding proteins. Besides NF-κB p65, a further candidate transcription factor is PAX

  Under optimized assay conditions, very low concentrations (20pM) of [125I]YP20 bound to hCRF1-CHO PSI-6206 and membranes with high specificity (>95% inhibited by 1μM astressin) and in a membrane protein-dependent manner.
