• E ubiquitin ligases are key players

  2021-05-07

  

  E3 ubiquitin ligases are key players in the ubiquitin-proteasome pathway because they catalyse ubiquitination of substrate proteins.39, 40, 41 As important regulators of cellular ubiquitination, E3 ligases are emerging as attractive drug targets, particularly in cancer.42, 43, 44 However, E3 ligases

  2021-05-07

  

  Despite the weak and transient nature of E2–E3 interactions, this binding is required for the transfer of ubiquitin to the substrate. The low affinity characteristics of this interaction may be due to the fact that E2s use the same surface to interact with E1s and E3s, and hence while binding to an

  2021-05-07

  

  Together, the protein engineering approaches employed by Teyra et al., (2019) demonstrate the effectiveness of affinity maturation for improving the affinity of UbVs, but this comes at a cost in terms of specificity. Indeed, the most effective UbV was the dimeric construct generated from UbVs isolat

  2021-05-07

  

  To determine whether the same concentration of humic GNE-7915 receptor causes changes in PCR efficiency, we performed another experiment in which the humic acid was added to the PCR mix after bisulfite conversion. All samples that were amplified in the presence of humic acid (thick lines) show a dec

  2021-05-06

  

  Despite many studies having demonstrated the importance of connexin43 (Cx43), the most abundant connexin in bone cells, for bone development and turnover during the last decade [27], little is currently known about GJIC and Cx43 in primary bone tumors. In this report, we analyzed the specific role o

  Introduction Prostaglandin E2 (PGE2) signals through 4 separate G-protein coupled receptor sub-types (EP1, EP2, EP3 and EP4) to elicit a variety of physiological and pathophysiologic effects. EP2 and EP4 increase cAMP levels in the cell via adenylate cyclase activation, whereas EP3 inhibits cAMP

  In contrast, a single instillation of BLM results in a progression of inflammatory events that culminates in marked remodeling of the lung interstitium. This process takes 2–3 weeks, with the fibrotic lesions becoming most pronounced within the first month [9]. Consequently, the BLM model offers the

  2021-05-06

  

  Mulan is one of three E3 ubiquitin ligases that are present in the mitochondria along with MARCH5/MITOL (membrane associated RING-CH5) and RNF185 [14], [15], [16], [17]. Mulan is a 352-residue polypeptide that crosses the mitochondrial outer membrane (OMM) twice, its amino-terminus, which includes t

  These studies suggested that PV/PVH might promote bone formation activities and/or inhibit bone resorption activities probably due to its anti-inflammation activity; however, the underlying mechanism remained unknown. Furthermore, it is unclear if PVH shows better activity than that of PV; this is i

  2021-05-06

  

  Mono- and bi-ubiquitination of two lysines, namely K70 and K76, in a small fraction of p33 replication co-factor has been demonstrated in yeast (Barajas and Nagy, 2010, Li et al., 2008). Because mutations of these lysines reduced TBSV repRNA replication in yeast and affected the ability of p33 to in

  The first ones class A receptors found as heterodimers were reported by Gomes et al. (2000), who identified a heteromer constituted by two subtypes of opioid receptors (μ and δ) in heterologous cells. The same year, Ginés et al. (2000) showed the first heteromer composed of two different receptors,

  2021-05-06

  

  Primases are classified into two major groups: first, the DnaG primases, found in bacteria and bacteriophages, and second, the archaeoeukaryotic primases. Remarkably, bacterial and archaeoeukaryotic primases have no structural similarity and, presumably, evolved independently (Leipe et al., 1999). T
