  2020-01-17

  

  Introduction Receptor tyrosine kinases (RTKs) are critically involved in the development and progression of human cancers and are therefore useful targets for anti-cancer therapies [1]. The Eph receptors represent the largest subfamily of receptor protein kinases and interact with ligands called

  Inhibiting APC/C during Interphase and prior to Anaphase Because ubiquitylation by APC/C triggers cell division, it is essential that APC/C is restrained until cells are prepared for its substrates to be degraded. In addition to regulation by phosphorylation, an additional layer of control comes

  2020-01-17

  

  The nuclear receptor related-1 protein, Nurr1 (NR4A2), is a transcription factor that regulates the SYBR Safe DNA Gel Stain of genes critical for the development, maintenance, and survival of dopaminergic neurons (Alavian et al., 2014, Decressac et al., 2013, Dong et al., 2016, Jankovic et al., 2005

  2020-01-16

  

  Ubiquitination is a covalent attachment of 76 amino Monastrol ubiquitin molecules to target proteins, either as single moieties (mono-ubiquitination) or as poly-ubiquitin chains of different structures, formed through isopeptide bonds between specific lysines of one ubiquitin residue (for example K

  2020-01-16

  

  Structure and function of EPAC isoforms EPACs are guanine nucleotide exchange factors (GEFs) for the Ras-like GTPases Rap1 and Rap2 [9]. There are two mammalian EPAC isoforms, EPAC1 and EPAC2 1, 2 (Figure 1). Whereas EPAC1 displays a wide tissue distribution, the expression of EPAC2 is more restr

  2020-01-16

  

  For most enolases, fluoride acts as an inhibitor, while Mg2+ is the most important metal activator. In yeast systems, metal cations and fluoride bind to enolase at the active center of the enzyme, forming a complex. The complex blocks the binding of substrates to the enzyme in yeast systems, thereby

  The contribution of Interference RNA and epigenetic in OA attenuation Interference RNA, a cellular mechanism for post-transcriptional gene silencing that is associated with mRNA. The potential of RNAi has successfully silenced the wide range of protein coding genes. Its high specificity sanctions

  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

  To study the role of DNA–PK in the response to replication arrest, we used the DNA replication inhibitor aphidicolin (APH). APH, a mycotoxin isolated from Cephalosporium aphidicola, inhibits DNA replication by interacting with the replicating DNA polymerase α (pol α). APH specifically inhibits the a

  Despite its significance in tumor suppression, the molecular mechanism by which DAPK is regulated and its interplay with other tumor suppressors and oncoproteins have not been completely unraveled. Although primarily regulated by CaM binding (Cohen et al., 1997), DAPK activity can also be modulated

  A surprising second functional effect was found in culture experiments. Inclusion of LTD4 reduced the frequency of Fas receptor (CD95) expression. Once again, this effect, although modest, was reversed by a cysLT1 receptor antagonist. The biologic significance of this effect or its mechanism remaine

  2020-01-16

  

  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

  EBI2 and its ligand(s) EBI2 was found in a screen of upregulated genes in human B cells upon infection with EBV [1]. EBI2 is a G-protein (Gαi type) coupled receptor [2] but as long as 18 years after its discovery the nature of its ligand remained undisclosed. With the help of transfected cell lines
