  2021-04-12

  

  Protein deubiquitination is becoming increasingly instrumental in understanding the complexities of the Ub system. Adding to this complexity is the discovery of bacterial effectors with DUB activity that have structurally adapted themselves to interfere with the eukaryotic Ub system (Pruneda et al.,

  2021-04-12

  

  Because stimulation and blockade of dopamine D2 receptor all cause a similar disruption of maternal behavior, one critical question is whether they do so through the same or different behavioral mechanisms. One idea is that stimulation or blockade of D2 receptors similarly suppresses maternal motiva

  Db model cells showed various aberrant phenotypes that seemed to reflect the pathological abnormalities found under diabetic conditions. First, in Db model cells after insulin stimulation, we found the inhibition of the transcriptional repression of the gluconeogenic genes, PCK1 and G6PC, and aberra

  Extracellular uridine can be transported across the cell membrane to enter the nucleotide salvage pathway. A colon cancer cell line supplemented with uridine was capable of growing normally in the presence of 1 μM brequinar (Peters et al., 1992). The supplemented uridine may be transported into the

  2021-04-12

  

  Previous studies showed that many steroidogenic enzymes act when the enzyme binds to the cofactor first [30]. In the present study, we showed that HPTE inhibited both AKR1C14 and RDH2 in a mixed mode when cofactor was used. This indicates that HPTE interferes with cofactor-binding residues although

  We had earlier reported that collagen fibers with intact native banded structure were occasionally observed in the kinase-deficient, membrane-anchored DDR2 ECD (DDR2/-KD) samples; however, in our DDR1/ECD and DDR2/ECD samples, observation of native banded structure of collagen was far more infrequen

  2021-04-12

  

  For a physiologically relevant interaction, ligand and receptor have to be expressed in the same place. Collagen II is found primarily in cartilage. DDR2 is expressed in proliferating chondrocytes in vivo, and its staining pattern in tibial growth plates is similar to that of collagen II. In additio

  2021-04-12

  

  Through the process of alternative splicing, the IKZF1 gene is capable of encoding a large number of Ikaros isoforms (Molnar et al., 1996). Some of these isoforms were shown to have distinct functions (Li et al., 2011, Ronni et al., 2007). Ikaros protein contains four zinc fingers at the N-terminus

  The instructive precedent for galectin phosphorylation is human galectin-3 (hGal-3). Its serine modification by protein kinase CK1 in the N-terminal tail is relevant for nuclear export during the course of apoptosis regulation and contact formation with the neural cell adhesion molecule L1 , , , .

  A possible explanation for these observations has been provided by a recent study showing that EWS-FLI-1 increases the Skp2-mediated 26S proteasome degradation, decreasing p27 protein stability and preventing cell senescence [42]. Mechanism of action of EWS-FLI-1 Molecular analysis has revealed

  Here, we report for the first time that EphB4 contains two NLS sequences and localises to the nucleus. This is mediated via an importin-α pathway and we show that EphB4 could potentially have a direct role in gene regulation. These data provide new insight into Eph receptor localisation and action a

  Considering these reports, and with the aim of further investigating the mechanism by which the cAMP-Epac/PKA pathway activates eNOS, we have performed imaging experiments evaluating the effect of drugs that increase cAMP or modify its signalling pathways (PKA or Epac activators and inhibitors) on

  Early developments Historically, the advent of SMEPT can be traced to the 1980′s, where the first example of localized prodrug conversion was achieved using a judiciously placed enzyme – in order to achieve a localized feed of 5-fluorouracil (5-FU). Immobilization of E. coli-derived cytosine deam

  O-GlcNAc transferase OGT belongs to the metal-independent GT-B superfamily of glycosyltransferases, which has been well-reviewed previously [14,15]. OGT is an essential gene encoded on the X-chromosome, and it has two main regions: a long N-terminal tetratricopeptide repeat (TPR) region and a C-t
