  In addition to cleaving ubiquitins off modified proteins, DUBs can also cleave between ubiquitin moieties within a polyubiquitin chain to edit the ubiquitin signal. DUBs employ different strategies to recognize polyubiquitin (Figure 1). DUBs that rely only on interactions on the S1 site tend to be c

  Other factors regulating DNA-PKcs Recent work in the field has also focused on factors that regulate NHEJ and NHEJ factors, in particular proteins that modulate DNA-PKcs. In this section we will highlight a number of factors which have been found to regulate DNA-PKcs. DNA-PKcs phosphorylation at

  2019-07-15

  

  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

• One step in pyrimidine biosynthesis

  2019-07-15

  

  One step in pyrimidine biosynthesis is conversion of l-dihydroorotate (DHO) to orotate (ORO), under action of the enzyme dihydroorotate dehydrogenase (DHODH, EC 1.3.99.11), which contains a flavine (FMN) as redox cofactor [1]. In this transformation, electrons resulting from DHO oxidation are transf

  2019-07-15

  

  One possible explanation for differences in the binding ability of monomeric versus dimeric forms of DDR2 ECD to collagen could be that the monomeric form only binds to the primary GVMGFO site, whereas dimeric (and oligomeric) DDR2 ECD binds to additional sites on the collagen triple-helical molecul

  2019-07-15

  

  In Hevea brasiliensis, both the soluble PPase and the membrane-bound V-PPase are present in the latex; the soluble PPase is in the C-serum (cytosol) of the latex [6] and the V-PPase is on the tonoplast of the lutoid, a special vacuole in the laticifers of rubber trees [7]. The V-PPase on the lutoid

  2019-07-15

  

  The crystal structure of the B. subtilis Maf (BSU28050) was published in 2000, and, to date, it represents the only experimental work with a purified Maf protein (Minasov et al., 2000). The structure revealed a structural fold similar to that found in ITPases and YjjX proteins, which are nucleotide

  2019-07-15

  

  Natural and synthetic glucocorticoids perform their biological action in the organism through receptor-dependent mechanisms (e.g., by binding to the glucocorticoid receptors). It has been determined that glucocorticoid receptors cross-talk with other nuclear receptors, including AhR (Celander et al.

  The physiological role of the UCNs in the regulation of the HPA axis is still under debate (Fekete and Zorrilla, 2007, Suda et al., 2004). UCN 1 was proved to increase the plasma ACTH and corticosterone levels in rats (Bagosi et al., 2014, Vaughan et al., 1995), whereas UCN 2 and UCN 3 were shown to

  2019-07-15

  

  Other mutations in the SYNE1 3′ region (exons 81–85) have been implicated in an upper motor neuron disease, ARCA1 (Gros-Louis et al., 2007). The disease is characterized by progressive movement, coordination, and balance problems caused by disrupted Purkinje cell function and their impaired signalin

  Therapeutic options targeting intrahepatic resistance are very limited. Theoretically, the NO-cGMP pathway may be influenced at several sites. Yet, most strategies did not reach clinical practice or yielded disappointing results, such as activators of soluble guanylate cyclase [14], NO releasing der

  It is known that cigarette smoke increases the oxidative burden in the lungs of mice with emphysema, which leads to oxidative stress [[34], [35], [36]]. However, in addition to cigarette smoke, studies have shown that endogenous oxidative stress is associated with proteolytic Saikosaponin A chemical

  Recent studies support the concept that dietary metabolites, such as retinoids and AHR ligands, regulate ILC3 function. These metabolites act through intracellular nuclear receptors that function as transcription factors, thereby controlling ILC activity through the stimulation of specific transcrip
