A previous study reported that it is unlikely that silkworm mounts a general type of immune response to all viruses (Liu et al., 2015). It is not clear whether there is a common pattern of host regulation for silkworm viruses. Spry is a general inhibitor of receptor tyrosine kinases (RTKs), which is

2021-08-10

cAMP-mediated signaling pathways are important for maintaining metabolic homeostasis, and the effects of the glucagon/catecholamine–cAMP–PKA axis on energy balance have been well documented [20]. For example, Berberine of the PKA 2β regulatory subunit (RIIβ) in mice leads to increased expression of

2021-08-10

The assembly and maturation of invadopodia can be initiated by chemical stimuli such as the epidermal growth factor (EGF), as well as the mechanical signals from extracellular matrix (ECM). Upon binding, EGF activates the EGF receptor (EGFR), which further activates several intracellular signaling p

Halogenases Enzymatic C–H activation leading to halogenation is another emerging area in biocatalysis [55,56]. Incorporation of halogen atoms during medicinal chemistry eff ;orts is a well-established practice, presenting an effective means to control the molecule’s bioactivity and physicochemical

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

2021-08-10

Enolase is an example of a moonlighting protein that displays multiple biological actions, including plasminogen, laminin, fibronectin, mucin and cytokeratin binding properties. It has also been described as a complement-evasion protein and as a protein capable of inducing neutrophil trap formation.

According to the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB, 1992), peptidases are divided into two classes, namely exopeptidases and endopeptidases, based on their actions on substrates and their active sites, respectively. Endopeptidases inclu

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

Several studies have demonstrated that αSyn specifically associates with lipid rafts (Cole et al., 2002), raising the possibility that the perturbation of rafts can affect the aggregation and phosphorylation of αSyn (Fortin et al., 2004). Schneider et al. (2010) described the potential involvement o

2021-08-09

Proinflammatory cytokines induce ER stress in many mammalian cell systems.32, 33, 34 Our results demonstrate that these cytokines also trigger ER stress in trophoblast JEG-3 cells. However, the severity of stress is likely low grade because only the PERK-EIF2A arm of the UPRER pathway was activated.

In mice, our EBI2EGFP reporter showed that EBI2 is expressed consistently in naive T helper cells. Already single positive CD4+ thymocytes express EBI2 (not shown). In effector and regulatory T cells in naive mice, the percentage of EBI2 expression was lower (∼40%). Like others (Liu et al., 2011), w

Taken together, these assays demonstrate that SUMOD positioning is essential for all E3 ligases but dispensable for E2 and S*E2 sumoylation reactions. Thus, we propose SUMOD positioning as a key criterion to describe the enzymatic function of SUMO E3 ligases that distinguishes them from other enhanc

External factors, such as protein partners, can also activate DUBs by either reinforcing the stimulatory effects of intramolecular factors or by other means. The intramolecular activation of the USP7 CD by its HUBL domain is allosterically potentiated by external factor GMP synthase (GMPS), which co

DNA-PK (Jackson, 1997) is activated by DNA double-stranded breaks (DSBs). It is a trimeric complex composed of the catalytic subunit, DNA-PKcs, and the Ku70/80 heterodimer. DNA-PK mediates non-homologous end joining (NHEJ), which joins programmed DSBs created during V(D)J recombination and class swi

Nowadays, colorimetric assay has been applied in detecting DNA MTase activity. Li et al. used DNA modified gold nanoparticles (AuNPs) coupled with enzyme-linkage reactions to detect the activity of methylases [20]. In a previous study, our group presented a label-free colorimetric method, using unmo
