  2021-03-13

  

  A brief history of RBR E3s RBR E3s were originally defined based on sequence alignments that predicted a tripartite motif of three zinc (Zn)-binding domains: two RING domains (RING1 and RING2) connected via an in-between-RING (IBR) domain [28], [29]. The prediction together with initial observati

  2021-03-13

  

  The RING domain was previously considered sufficient to confer ubiquitination by RING-type E3 ligases. However, recent reports have shown that sequences closest to the RING domain are also important in E3 ligase function. Residues like Tyr193 in RNF4 [40], Phe296 and Arg294 in BIRC7 [31], and Lys65

  2021-03-13

  

  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

  2021-03-13

  

  Introduction Protein ubiquitination is a posttranslational modification that plays a major role in almost all cellular processes in eukaryotes (Hochstrasser, 2009; Komander & Rape, 2012). It involves the covalent attachment of ubiquitin (Ub) via its C-terminal glycine carboxylate to a primary amine

  2021-03-13

  

  DDR1 upregulation in patients with kidney diseases such as lupus nephritis and Goodpasture's syndrome [8] as well as in animal models of kidney injury [7], [8], [18] suggests that DDR1 plays an important role in kidney disease. Studies in various mouse models of kidney injury indicate that DDR1 dele

  Acknowledgements Introduction α-L-Rhamnosidases (EC 3.2.1.40) are glycosyl hydrolases (GHs) that cleave terminal α-l-rhamnose from a large number of natural products [1]. The action of α-L-rhamnosidases (α-RHAs) has been reported, among others, on different complex substrates such as heteropol

  Constitutive activity of Ras/Raf/MEK/ERK pathway plays a critical role on melanoma growth, thus inhibition of activity of Ras, Raf and MEK can reduce ERK activity, leading to a decrease in melanoma cell proliferation, survival and invasion (Burotto et al., 2014; Paluncic et al., 2016).

  Our results indirectly support the combination of resveratrol and hesperatin treatment for PDN, as this induces GLO1 activity in patients (Xue et al., 2016), as well as metformin, an FDA-approved anti-diabetic treatment, which acts as an MG scavenger to reduce MG levels in type 2 diabetic patients (

  The different serotypes (A-G) have unique receptors to which they bind to produce the toxic effect on the nerve cells. (Lance, 2004, Rosetto et al., 2014). Intracellularly, the endopeptidase activity of different serotypes of BoNT target selectively a unique group of proteins, the SNARE Nelfinavir M

  We can think of two ways in which collagen binding could activate DDR (Figure 8). A single collagen triple helix could interact with both DS domains in the DDR dimer (“composite binding site”) and thereby activate the receptor, similar to the situation exemplified by the growth hormone-growth hormon

  As mentioned above, EBI2 and its ligand show some similarities to the sphingosine 1-phosphate (S1P)/S1P-receptor system, which mediates T cell egress from lymph nodes. Blockade of this system yielded in the first oral drug for MS patients named fingolimod. Therefore, the hope that EBI2 deficiency wo

  In light of this, our finding that UBTD1 interacts with ubiquitin conjugating enzymes is intriguing. Using two different screening approaches, we have demonstrated that UBTD1 interacts with the ubiquitin conjugating E2D family proteins. Using purified recombinant proteins and gel filtration chromato

  E1 is encoded by the largest and most conserved open-reading frame (ORF) of the PV genome. The protein ranges in size from 600 to 650 amino acids, depending on the PV type. Overall, the protein can be divided into three functional segments: an N-terminal regulatory region that is essential for optim
